Drug analysis a multistep process - CNN.com
In standard screening, blood samples are drawn from various areas of the body, including the leg and heart, because drugs and poisons can circulate, toxicologists say. The initial screening test using blood and urine samples indicates what type of drugs -- for example opiates, cocaine or amphetamines -- might be present.
"It points you in the right direction," Anderson said. But the results are not conclusive.
In order to confirm that a person had a specific type of drug in his or her system, the drug must be extracted from the specimen. More complicated cases could require samples of the liquid in the eye, bile, or tissue from the liver, kidney, stomach or lungs.
"The drugs must be physically separated from the biological matrix," Caplan said. "If it's liver or blood, you have to do preparations for the extraction procedure, which is often multistep." This can also take several days, he added.
The specimen is mixed with an oil solvent, which attracts the drugs away from blood or tissue sample. Then the solvent is evaporated, leaving the various chemicals.
"You have to purify the drugs out of this mix of things, which has lots of other chemicals in it that may interfere," Anderson said. This preparation has to be done for every specimen undergoing analysis.
An instrument called a gas chromatograph-mass spectrometer separates the compounds and provides information to enable toxicologists to identify them as specific types of drugs. One positive finding can lead to more tests of different samples, triggering a sequence.
"You have to make a series of tests," Anderson said. It "can take a long time to complete the whole battery of tests. If you find something, you go back and quantify it. And you do have a lot of other investigations you're going through at the same time."
