Urine analysis vitamin c positive is how to return a responsibility

If vitamin C (+) is present in urinalysis, it is not clinically significant and is often a reference to test results. Vitamin C (+) can cause many false negatives, such as pyuria, proteinuria, hematuria, and nitrite. For example, when urinary tract infection occurs, the increase of nitrite in urine indicates that there are bacterial infections such as Escherichia coli, Proteus, Klebsiella, etc. in urine. When high concentrations of vitamin C are present in urine, the expression of nitrite can be caused to be (-. Therefore,(+) of vitamin C in urine is mainly used for auxiliary analysis of some results.
