What most of them cause is diuresis (increased excretion of urine), which means the athlete is providing diluted urine sample, almost water. In NCAA drug testing, the athlete is required to provide a concentrated specimen that passes a specific gravity cutoff. If the specimen is too diluted, he has to provide another sample.
Urine drug testing is one of the most common testing methods used. The enzyme-multiplied immune test is the most frequently used urinalysis. Complaints have been made about the relatively high rates of false positives using this test. [18] Urine drug tests screen the urine for the presence of a parent drug or its metabolites.
Enzyme multiplied immunoassay technique (EMIT) is a common method for qualitative and quantitative determination of therapeutic and recreational drugs and certain proteins in serum and urine. [1] It is an immunoassay in which a drug or metabolite in the sample competes with a drug/metabolite labelled with an enzyme, to bind to an antibody. The ...

The drug test ranges from testing player-enhancement drugs to marijuana. A student failing a drug test loses one year of eligibility and is not allowed to compete in events for the first offense. [2] However, not all students are tested because they are selected at random, but students are subject to be tested at any point in the year after the ...
A drug, if present in the urine specimen below its cut-off concentration, will not saturate the binding sites of its specific antibody. The antibody will then react with the drug-protein conjugate and a visible colored line will show up in the test line region of the specific drug strip. [citation needed]
USADA collects both blood and urine samples during in-competition and out-of-competition tests, which can occur at any time, at any location, and without advance notice. Comprehensive, no-notice testing programs like USADA's that are consistent with the WADA Code have often been referred to as Olympic style drug testing.
A urine test is any medical test performed on a urine specimen. The analysis of urine is a valuable diagnostic tool because its composition reflects the functioning of many body systems, particularly the kidneys and urinary system , and specimens are easy to obtain. [ 1 ]
