Anyone good at looking at lab results?

Your lab values are classic for a 250 lb. hard training athlete. Your creatinine value is no exception to this, in fact, if norms were established for this demographic 1.9 would be well within normal limits. If concern is to be established for your health given the information you supplied, I would be more inclined to consider the implication of your mild thrombocytopenia with platelets of 138K. This is the only deviation from what is classically considered to be normal that is not explained by your size and proclivity for pursuing resistance training. Your test levels are most consistent with either chronic (but not current) androgen use, recently discontinued short term androgen use, or endogenous mild hypogonadism. The biggest threat to your health in reality is none of this stuff, but rather the fact that at age 35 you insist on acting like an asshole and end up in fights where you go through plateglass windows. This is not only childish and embarassing, but it is unnescessary, and now you are having surgery as a result of it. Do yourself a favor--grow up and quit acting like such a jagoff.

The more I research this the more it looks like I am correct that the high creatine levels are a result of having more muscle than the average person.
Still, tomorrow I get to pee in a jar all day. I guess its better safe than sorry.
I don't like knowing more than my Dr. Thats not a good sign.
BTW. Even though I have not been working out due to injury I am probably (at worst) 20% body fat. That puts me at over 200lbs of LBM. That would give me high creatine levels and also a low eGFR reading.


LOLOLOLOLOLOL,

Consider the 24 hour collection your bad karma for being such a plonker with the plate glass window.

I do know what you mean about the lab stuff. I had my lab and consultant to converse with, it is difficult for GPs to keep up with ALL of the new and relevant testing and clinical information, so I would give him a break.

Did you mention the differences in muscle mass and using cockcroft-gault formula to him?

Also, with regards to more testing, some of the things he is asking for are a bit odd.

ESR - completely useless test unless you have rhematoid arthritis or myeloma, seriously it is over 100 years old and basically measures how quickly RBC settle in serum which is why is called a erythrocyte (RBC) sedimentation rate. Any doctor that still uses this test is YEARS behind in diagnostics.

ANA - anti-nuclear antibodies? Why is he testing you for autoimmune disease, and autoimmune of the liver?

Hep screen- again, this would related to elevated liver enzymes, not anything renal.

UA?????- why is he doing uric acid? This is related to people having connective tissue disorder, in particular gout.


Your labs are behind in the US, the more I see, the more I am convinced of it.

You are not getting rid of old and outdated tests or keeping up with current clinical chem knowledge.

The eGFR was introduced as it was just effective if not MORE effective in detecting early renal disease than the 24 h urine collection.

I do think that a lot of the testing done is related to making more money.

Ask your doctor if he had connections with the lab.
 
Show this to your doctor

Paul D Giles and David A Fitzmaurice argue that the introduction of estimated glomerular filtration rate to screen for chronic kidney disease in primary care will lead to pressure on specialist services and create patient anxiety without clear proof of benefit


Chronic kidney disease is a public health problem worldwide.1 The estimated prevalence of established renal failure is around 1400 per million in the United States and more than 600 per million in the United Kingdom. Patients with chronic kidney disease have increased risk of cardiovascular disease. A test that reliably detects early kidney disease could help minimise cardiovascular disease and renal failure.


Estimating glomerular filtration rate
The best known function of the kidneys is plasma filtration—measured by the glomerular filtration rate (GFR). Many of the kidney's functions are related to GFR (box 1). Inulin clearance and modern isotopic methods are not practical for measuring GFR in routine practice. Creatinine based tests are used instead but have several disadvantages. Creatinine clearance involves timed urine collection and is prone to error. Measuring serum creatinine is easier but this test cannot detect early kidney disease.2 Routine reporting of estimated GFR using formulas based on serum creatinine concentration plus age, sex, and racial group was first advocated in the US and has now been recommended in many other countries.




Box 1 Functions of the kidneys related to glomerular filtration rate3

Excretion of nitrogenous waste, sodium, free water, potassium, phosphate, and water soluble medicines (such as digoxin and gentamicin)

Control of blood pressure

Acid-base balance

Secretion of erythropoietin

Hydroxylation of vitamin D1 (activation)

Gluconeogenesis in the fasting state

Catabolism of peptide hormones (including insulin)


In the UK the second part of the national service framework for renal services,4 published in 2005, required clinical biochemistry laboratories to develop automatic reporting of formula based GFR estimates. In 2006 the quality and outcomes framework5 asked primary care to establish registers of patients with estimated GFR worse than 60 ml/min/1.73 m2 (chronic kidney disease stages 3-5 in the international classification; table).6 7 Many registers have been populated using computer programs that find serum creatinine results in general practitioners' information systems and then calculate estimated GFR using the "four variable version of the modification of diet in renal disease" (MDRD) formula (box 2).8




Box 2 Estimating glomerular filtration rate (GFR) using the four variable version of the modification of diet in renal disease equation

GFR (ml/min/1.73 m2)=186x{[Scr/88.4]–1.154}

xage in years–0.203

x0.742 if female

x1.21 if African American

Where Scr is serum creatinine in µmol/l


Labelling patients as having chronic kidney disease in this way has caused controversy.2 We challenge some of the applications of GFR estimated from this formula.

Clinical indications for assessing glomerular function
Glomerular function is assessed for three different reasons, which have an important bearing on the qualities required of the test.

Detecting changes in renal function over time
A test to monitor change in renal function over time in individual patients will need to be reproducible. Serial serum creatinine measurements are useful in this context because they are analytically precise and vary little over time in patients with stable disease, although meat rich meals and other non-renal factors can interfere.9 Because formula estimated GFR is a mathematical transformation of serum creatinine that takes into account three factors that have no measurement error and that do not change (sex and ethnic group) or change slowly (age), it is just as sensitive as serum creatinine at detecting change over time. It does not, however, provide a more reliable measure, except in the longer term, as changes in estimated GFR mirror changes in creatinine, and errors in measuring creatinine or interference in serum creatinine by non-renal factors translate into errors in estimated GFR.

Disease staging in patients with chronic kidney disease
The classification of chronic kidney disease is based on GFR,6 so a reproducible and accurate method is needed for the correct staging of patients with this disease. Formula estimates of GFR must agree closely with reference method determinations, not just on average across a tested population but for each individual being tested. In stages 3-5 of disease estimated GFR has no bias against isotopic reference methods, and in plots of the two methods the scatter between individuals decreases as GFR decreases. Estimated GFR is arguably accurate enough to stage patients with known chronic kidney disease with a GFR less than 60 ml/min/1.73 m2 (fig 1).10 Different patients with the same serum concentration of creatinine can have widely divergent degrees of renal impairment, so the formula can clarify loss of function in a way that is not directly apparent from the creatinine concentration itself. As estimated GFR improves, however, the scatter of estimated GFR plotted against reference GFR becomes progressively wider, and some biochemistry departments do not specify actual values for estimated GFRs higher than 60 ml/min/1.73 m2.9 It should be noted that the average serum creatinine concentration in the original MDRD data was around 200 µmol/l, the average GFR was about 40 ml/min/1.73 m2 (disease stage 3), and few patients had serum creatinine within the reference range (124 µmol/l).






Fig 1 Association of estimated glomerular filtration rate (GFR) with GFR measured by an isotopic reference method. Below 60 ml/min/1.73 m2 the two methods are tightly associated, with limited scatter of the points. At higher filtration rates scatter becomes progressively worse, and in kidney donors estimated GFR underestimates renal function compared with reference measurements. Adapted from Poggio et al10




Detecting chronic kidney disease in mixed populations
This is what primary care has been asked to do by creating disease registers on the basis of estimated GFR less than 60 ml/min/1.73 m2 and what a laboratory does if it reports estimated GFR with all adult creatinine results, regardless of the serum creatinine value or the patient's circumstances. Effectively, a screening test has been introduced without reference to the criteria for appraisal of proposed screening programmes endorsed by the National Screening Committee in 2003.11 GFR estimates based on the MDRD formula have been implemented in a setting far outside the original evidence base, with no proof of reliability in the new context, and without evaluating the balance of benefit to harm for tested individuals or the use of healthcare resources. This is in stark contrast to the methodical way in which the National Screening Committee assessed and rejected the evidence for urine testing to screen for bladder cancer and glomerulonephritis in 2002 (reconfirmed in 2006).12
In such a screening situation we need to know the sensitivity and specificity of the test and hence the predictive values of positive and negative tests in the tested population (using the prevalence of the disease in the population where the test is being applied). Here, the value of formula estimated GFR is unclear.

Although estimated GFR reflects the true filtration rate in patients with chronic kidney disease, several studies have shown that formula estimated GFR underestimates renal function in people without known kidney disease. This problem is compounded by enormous variation between individuals, and this unpredictable scatter gets worse as GFR increases (fig 1).10 13 14 15 These effects increase the overlap in estimated GFR values when testing patients with and without chronic kidney disease and significantly compromise the ability of estimated GFR to separate these two patient groups.

The risk of many false positives occurring is high. False positives are acceptable in screening tests if simple confirmatory tests can distinguish between true and false positives, and if patients are unharmed while the uncertainty is resolved. The problem here is that the follow-up "test" may be referral to a renal clinic (a precious resource in limited supply); also, patients may be entered on a kidney disease register, which may result in their having difficulty getting life insurance and being prescribed drugs (including angiotensin converting enzyme inhibitors5) on the basis of an inadequate test. Primary care clinicians realise this and may not label people as having chronic kidney disease even when estimated GFR values are below 60 ml/min/1.73 m2.


Analytical considerations
Numerous versions of the traditional method of determining creatinine concentrations (Jaffe chemistry) exist as well as more specific enzymatic methods. There are analytical differences between these techniques and a lack of standardisation.9 Figure 214 shows a scatter plot of estimated GFR against GFR measured by an isotopic reference method in people with normal serum concentrations of creatinine. Two estimated GFR values were calculated for each patient—one using the results of a creatinine assay based on Jaffe chemistry and one using results of an enzymatic method. Compared with the reference GFR method, the MDRD formula underestimated GFR for both creatinine assays, but more so for the Jaffe related results (about –27%) than those based on the enzymatic assay (about –10%).

Laboratories should obviously try to minimise variations between creatinine methods,9 but even if all analytical problems were resolved concerns remain about using estimated GFR in patients with lower serum creatinine concentrations. Even within one enzymatic method, one study showed a significant overall negative bias and substantial interindividual scatter of results—an estimated GFR at the threshold value of 60 ml/min/1.73 m2 could correspond to a reference method GFR between about 40 ml/min/1.73 m2 and more than 100 ml/min/1.73 m2.14







Fig 2 Scatter plot of estimated glomerular filtration rate (GFR) against isotopic reference GFR in subjects with normal serum creatinine using two different creatinine assays (enzymatic and Jaffe methods). Formula calculations underestimate GFR for both assays. The negative bias is less with the enzymatic assay, but the scatter of results is wide with both methods. Adapted from Verhave et al14





Conclusion
In some patients, the glomerular filtration rate may be half that seen in healthy people before serum creatinine rises above the population reference interval.16 Because serum creatinine is so insensitive for detecting early loss of renal function, it is tempting to suppose that estimated GFR is a better measurement. In reality, however, this is not true as the reliability of tests depends crucially on the population to which they are applied and on errors that come into play in different circumstances.

Our view is that estimated GFR is useful for staging disease in patients with stage 3-5 chronic kidney disease, and many nephrologists use estimated GFR and serum creatinine to monitor progress in such patients. To make estimated GFR more reliable laboratories should work towards greater uniformity in the assay of serum creatinine,9 and sample collection should be standardised to minimise the impact of non-renal factors (such as meat intake) on serum creatinine results.17 Serial measurements of serum creatinine and estimated GFR in individual patients may help clinicians detect changes in renal function even when serum creatinine remains in the population reference interval.

However, none of these initiatives will overcome the underlying weak association between estimated GFR and GFR measured by reference methods in people with normal or near normal renal function. Creatinine is a fundamentally flawed filtration marker, as too many non-renal factors affect its concentration in serum; we need a more reliable indicator of early loss of GFR.2 In the meantime, the uncritical introduction of estimated GFR in biochemistry laboratories and in primary care in adults with normal serum creatinine and no other indication of renal disease lacks a good scientific basis; it will lead to pressure on specialist services and create patient anxiety without clear proof of benefit.




Summary points

Estimated glomerular filtration rate (GFR) has come into widespread use as a result of the recent UK recommendations

Estimated GFR is useful for staging progress in patients with established kidney disease but collection of blood samples and creatinine assays should be standardised

The use of estimated GFR to screen for chronic kidney disease in primary care needs careful evaluation

Editorials

Glomerular filtration rate
Screening cannot be recommended on the basis of current knowledge


Low glomerular filtration rate predicts cardiovascular disease, end stage renal disease (a requirement for dialysis or transplantation), and death.1 In a population based study reported in this week's issue, Hallan and colleagues describe the yield of different screening strategies aimed at identifying people with low glomerular filtration rates.1 The guidelines of the United States kidney disease outcomes quality initiative define chronic kidney disease as glomerular filtration rate persistently lower than 60 ml/min/1.73m2, persistent urine abnormalities, or clinically relevant anatomical abnormalities, and they recommend measuring serum creatinine to determine estimated glomerular filtration rate in high risk groups.2 The Kidney Disease Improving Global Outcomes Group (an international organisation that seeks to improve care and outcomes for people with kidney disease) and draft UK guidelines endorse the classification but do not, at present, look at screening.3 4

All screening programmes cause physical, psychological, and social harm through the screening test itself, and through the investigation and treatment of abnormal results. No trials to show whether the benefits of screening for low glomerular filtration rate outweigh the harms have been conducted. So how should we proceed in the absence of such a trial?

The figure shows some areas in which the information needed to define a screening strategy is missing. Because low glomerular filtration rate is associated with cardiovascular disease, screening patients with established cardiovascular disease or risks for disease rather than unselected populations will lead to lower numbers needed to screen to identify one person.1 However, many people identified this way will have indications for interventions that randomised controlled trials have shown to prevent cardiovascular disease, end stage renal disease, or death, which limits the potential for differential intervention (application of treatments that would not have been used otherwise). Lower numbers needed to screen can also be achieved by screening older people,1 but the same consideration applies.


The screening test and "screen positive" threshold also need to be defined. Many authorities recommend using the estimated glomerular filtration rate.2 3 4 In the study by Hallan and colleagues, 20% of people with estimated glomerular filtration rates lower than 30 ml/min/1.73m2, but only 1-2% of those with values of 30-60 ml/min/1.73m2, progressed to end stage renal disease over eight years. Many people in the community (especially elderly people) with low glomerular filtration rate have disease that does not progress, which further limits the potential benefit of screening.1 5
Identifying people with a low glomerular filtration rate may lead to harm from labelling. For example, in people screened for hypertension at work, positive results can result in absenteeism and reduced income.6

Little research has been conducted into which tests should be done to diagnose possible underlying kidney diseases in people with low glomerular filtration rate.

Because estimated glomerular filtration rate and serum creatinine are continuous variables, and because of uncertainty about normal values and how they change with age, many people with results just above the screening threshold cannot be told that they have normal values. These people cannot be fully reassured, but do not benefit from additional treatment, and they will only be harmed by screening.

The purpose of screening is to identify people who should be treated differently. Angiotensin converting enzyme inhibitors,7 angiotensin II receptor blockers (in people with diabetes8), and low protein diets9 help prevent end stage renal disease in people with low glomerular filtration rate. Evidence of the benefit from angiotensin converting enzyme inhibitors and low protein diets comes largely from studies of people referred to nephrologists and may not generalise to people at lower risk.10 Two further issues exist—additional benefits from angiotensin converting enzyme inhibitors and angiotensin II receptor blockers will be limited to people not already taking them for other indications; and the intensive dietary education to prevent malnutrition that has been used in studies on low protein diets is not practical for large numbers.

Given the obstacles to the design of a screening strategy, what are the research priorities? More information is needed on how age, proteinuria, kidney function, diabetes, and blood pressure combine to predict progression to end stage renal disease, cardiovascular disease, and death in the general population. The proportion of people in candidate risk groups in whom treatment would be modified on the basis of data on kidney function must be defined. Modelling studies would identify whether potentially cost effective screening strategies exist; if so, these should be tested in randomised clinical trials.

In the meantime what should clinicians do? The study by Hallan and colleagues found that screening people with hypertension, diabetes, or age over 55 was the most effective strategy—93.2% (95% confidence interval 92.4% to 94.0%) of all cases of chronic kidney disease were detected, and the number needed to screen to find one case was 8.7 (8.5 to 9.0). Rather than screening, case finding should therefore continue in patients who have risks for or evidence of kidney disease, who are taking drugs that affect kidney function, or whose comorbidities make knowledge of kidney function important. Wide use of angiotensin converting enzyme inhibitors in people who have cardiovascular disease or diabetes and another cardiovascular disease risk factor will automatically treat many people with low glomerular filtration rate and will prevent cardiovascular disease and death.11 Maximising the proportion of hypertensive people who attain conventional blood pressure targets will prevent cardiovascular disease and death and is also likely to prevent end stage renal disease.

That was awesome. I am doing my best.
 
Okay, I am going to have the other tests done today!
Guess I will be peeing in a jar for the next 24 hours...
 
I had 5 viles of blood taken yesterday. Not fun.
I have to hold off on the jar-o-pee until next week. I guess it has to be from 8am to 8am... and kept in the refridgerator!
 
Okay, I pee'd in a jar for 24 hours. Dropped it off today. I should have some answers pretty soon.
I left a message at the Dr's office today just in case the blood work was in. I would like to get a look at my lab's before I see my Dr again.
I should have the results for the labs and the urine sample by the end of the week at the latest.
Should be interesting!
 
So my Dr is supposed to be calling me today with the results.
In the mean time my coworker sisters is a kidney specialist. He sent my original results to her. She looked at them and said "tell your friend not to use anabolics anymore"
I never mentioned anything about it. Its been a year or so since I touched anything and it was always a small amount.
So now he is laughing because she said if my new tests come back indicating some issues they will have to get a bone marrow sample. Can't say I am too excited about that.
