In brief: Urine results

These results could be all false positive, but he needs to be evaluated further by repeat ua and culture.
Nitrites can be positive from air exposure, contamination or phenazopyridine. Protein can be present transiently from benign causes such as standing for a long time. Bilirubin and uribilinigen can be due to liver/biliary problems. Rbcs can be due to infection, stones, tumors or kidney disease.

This is good advice. Repeat the test on a clean specimen, preferably a second voided specimen in the early morning.
