Urine tests are typically performed in a private setting to ensure confidentiality. The individual may be asked to wash their hands before providing a urine sample. The sample is then analyzed for various substances including drugs, proteins, or sugars.
Mixing water with urine will dilute the urine sample, potentially affecting the accuracy of the urine test results. The concentration of substances in the urine, such as drugs or metabolites, may be lower than expected, leading to false-negative results. Dilution of the urine sample is generally considered an attempt to cheat or manipulate the test.
Athletic Drug TestingThe most common method of testing is chemical analysis using a urine sample. An athlete at the Olympics is required to give two urine samples (commonly refered to in the media as the A and B samples - which are kept in separate places). The A sample is tested chemically for substances on the banned substance list. If a substance is detected in the A sample the B sample is then tested. If both samples are positive for a banned substance then the athlete is asked to explain the findings at a hearing.
It makes no difference - if you are using drugs illegally, you should not become a nurse.
