What is a normal UPCR?

Normal UPCR is 0.3 g/g (equivalent to 300 mg/day protein) indicate significant proteinuria requiring evaluation.

How does UPCR compare to 24-hour urine protein?

UPCR correlates well with 24-hour urine protein in stable patients (UPCR g/g is approximately equal to 24-hour protein in g/day). It is preferred for convenience and accuracy.

What proteinuria level suggests nephrotic syndrome?

UPCR > 3.5 g/g (3,500 mg/g) indicates nephrotic-range proteinuria, associated with nephrotic syndrome (oedema, hypoalbuminaemia, hyperlipidaemia).
