ANS:

Ans. The key is C. Urine porphobilinogen. This is wrong key. Correct key for this question is B. None. [This is a case of purple urinary bag syndrome for which we do urine RME that shows no nitrates and blood cells positive. pH is alkaline (>7). Sometimes culture is done but sensitivity is not needed as no antimicrobial treatment is recommended].
