Why does a different steroid test have to be developed for each anabolic steroids?

Anabolic steroids work in the body because they bind to the cellular receptors for testosterone and stimulate the testosterone response in the body. However, drug tests are more selective than these receptors, and so a different drug test has to be developed for each anabolic steroid. Why is this?

1. because each one has a slightly different metabolite... most steroids are slight variations of testosterone and when your body metabolises them, each one creates a slightly diff metabolite.. if you are taking testosterone though, then a blood test must be used.. your body alread has testosterone in it so the precense of testosterone metabolites does not necessarily mean a postitive for steroid use,, test is normally tested for using some type of medically accepted scale that creates limits for the normal amount of test that would be in a normal person of a certain age etc... if you have more test floating around in you then you are suspected of adding into your system
