A member asked:

Can urine that say out too long before being tested show a false positive result of nitrites?

A doctor has provided 1 answer

It is possible: A false-positive nitrite test result may occur when a urine specimen has remained at room temperature for an extended period of time and bacterial contaminants are allowed to multiply and produce measurable levels of nitrites.
