Be very careful here.
Get a test, fine. The results go on your medical records.
If the results are very very strange, they must be explained.
Very high or very low Testosterone is not normal, so there are of course questions asked as to "why".
The results of the test, and your discussions with the doc, typically get placed into your medical record. Even if you assume its "confidential" which it is, the test results are still placed in your medical record.
That medical record is reviewed by an future insurer. So, if sometime down the road, you go to get insurance, that new carrier will request access to your records, and if/when they review them, they may see mention of these results, and will ask why they were very high or low.
This is not a problem if you are an "employee" and a part of a group insurance plan. However if you are self-employed, or an independent consultant of some type ..... then the insurance companies will probably use strange test results as a reason to either not cover you, or charge you an astronomical rate.
If you live in Canada, this is probably not an issue.
However, in the US, this is a huge problem.
Even IF the Doc agrees to not make any records of the conversation you have with him, and not place your discussion into your record, the test results WILL go into the record. And most Docs do not have the means to get any type of “confidential” Testosterone test done (where they do not associate your name with the actual test results).
