Completely misunderstood the information you may have received. A urine test for infection does not "age". The freshly collected urine is incubated in appropriate media such as agar, and it takes from twelve to 48 hours for the growth of bacterial colonies to be detected, isolated, identified, and determination of sensitivities of that organism to common antibiotics determined. In no way is the urine aging. Much like planting seeds and having to wait for them to germinate. And a test for drugs is done on fresh urine, or urine properly preserved or frozen if there is going to be any delay.
