Radiographic media and some antibiotics, especially penicillin, ampicillin, and cephalosporins, may interfere. Wait 48 hours before collecting the spot urine. Grossly icteric samples give false-positive results and are not satisfactory.
Additional Information
Recent evidence indicates that protein/creatinine ratio is closely correlated with excretion of protein on 24 hour urine.
