4752 Nitrites in urine

Code and name of test:

4752 Nitrites in urine

The test is based on the bacterial conversion of nitrate to nitrite (and the appearance of pink on the related area on the strip) and is specific for the presence of bacteriuria. The presence of white blood cells in a large amount and of nitrites in urine signals a urinary infection caused by bacteria.


A single negative result does not rule out urinary infection because the number of bacteria and the nitrate content in urine can vary greatly. On the other hand, repeatedly negative results can occur in the presence of a pathogen which does not form nitrites.
