If you mix water with urine what will be the results of a urine test?
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.

Why does urine have to be diluted so heavily for a Jaffe's reaction test?
Diluting urine for a Jaffe's reaction test helps to minimize interference from other substances in urine that may give false-positive or false-negative results. The dilution helps to ensure that the color change observed in the reaction is due specifically to the creatinine concentration in the sample.
