Clinical definition of adult nephrotic syndrome

1. Proteinuria: ≥3.5 g/day and continuous (comparable to ≥3.5 g/gCr at spot urine)

2. Hypoalbuminemia: Serum albumin ≤ 3.0 g/dL

Serum total protein ≤ 6.0 g/dL is helpful

3. Edema

4. Dyslipidemia (Hyper LDL cholesterolemia)

The above urine protein and hypoalbuminemia are indispensable prerequisites for the clinical diagnosis of nephrotic syndrome

Edema is not an indispensable prerequisite but an important finding for nephrotic syndrome

Dyslipidemia is not an indispensable prerequisite for nephrotic syndrome

Oval fat body is helpful for diagnosis of nephrotic syndrome
