The diagnosis of nephrotic syndrome, which generally has 4 clinical diagnoses, does not often say what is not included and what indicators are commonly included. The diagnosis of nephrotic syndrome includes hypoalbuminemia, profuse proteinuria, hyperlipidemia and edema. Hypoalbuminemia is mainly albumin in the blood below 30 g/L. Massive proteinuria is increased foam in the urine, with more than 3.5 g of urine protein in 24 h. Edema is mainly seen in the eyelids and bilateral lower extremities edema. Hyperlipidemia refers to significantly higher than normal triglycerides and cholesterol in blood biochemistry. If the patient presents with generalized non-depressed edema, it suggests cardiac insufficiency. If the patient presents with hematuria and red urine, it suggests nephritis rather than nephrotic syndrome.
