Causes of falsely positive tests
Often these tests are falsely positive, meaning that the test will show the presence of anabolic steroids but the individuals has not taken anything illegal. Some of the reasons for this include:
Taking oral contraceptives which contain norethisterone. Thus, all women must tell the sporting agencies what type of oral contraceptive they are taking
If someone is pregnant
Someone who has ingested animal products which have been injected with steroids
Some medical disorders where there is an overproduction of testosterone- usually cancers
Consumption of certain plants (yams) can induce a positive test
Cost
Testing for anabolic steroids using GCMS is relatively expensive. A single test costs anywhere from $150- $250 depending on who does it. Because testing can get to be expensive when done on hundreds of athletes, only random testing is performed. Often the tests have to be repeated to ensure that one has a true reading. Cost is a limiting factor and is the reason why these tests are not routinely done.
Final Word
Despite all the buzz about steroid testing, chances are likely that one will never get tested. In any case, the testing is getting sophisticated and can detect very low levels of anabolic steroids in the urine. The best way to not get caught is simply not use steroids.
