Best method of estimation of amount of proteinuria in a 2 year child with nephrotic syndrome is: (A) Dipstick testing, (B) 24 hr urine protein, (C) Spot urine sample for protein/creatinine ratio, (D) Microalbuminuria
Answer is C. c. Spot urine sample for protein/creatinine ratio(Ref: Nelson 20/e 2518)Though 24 hr urine for protein and creatinine, is more accurate, but due to difficulty in collecting 24 hour urinary sample in children, Spot urine sample for protein/creatinine ratio is preferred.
