Current scientific evidence indicates that their fears are misplaced. male muscle pictures Effect of anabolic steroids. Urine contains thousands of bacteria from many different species. This is even more the case for a sexually active female. Urine collected from a female athlete will contain skin cells and microorganisms from the intestine flushed to the vaginal area by sweat. male muscle pictures Description of anabolic steroids. Many bacteria are ubiquitous and survive even in tap-water plumbing; if the water were used to wash any of the sample containers, other microorganisms could be added to the sample. Bacteria, in a container to which urine is added, will flourish in such a medium that is infinitely richer in nutrients than the water in which they have survived. Many constituents of urine support the growth of such bacteria, and metabolism presents a serious problem in drug testing because of the risk of falsifying doping test results. male muscle pictures Description of anabolic steroids. In this regard, urine contains several steroids that are utilized by bacterial enzymes that can interconvert endogenous steroids to the extent of producing testosterone in the urine. Because of the steroid concentrations in the urine, even a low conversion rate of steroids to T will produce a level of T sufficient to distort the test result. So athletes should be more concerned if officials don't add something to the urine sample and not the other way around. Laboratory ProtocolsLaboratories need to maintain high standards of practice in order to retain the respect of the sports community. In the event of an appeal for a positive test result, the data and procedures may have to withstand scientific and legal scrutiny. This makes accurate and complete presentation of the results essential. Accredited laboratories involved in drug testing may also exchange samples in a quality control program to confirm that they agree on the findings. If a lab comes up with results that are not consistent with other labs, they fail the quality control tests and accreditation can be withdrawn. While these quality control tests are not usually made public, some experts feel that they should be made available to all parties, especially in the case of legal disputes.
