AKR | Albumin per day | PKR | Proteinuria per day | |
Normal | 0-3 | 0-30 mg / day | <200 mg / day | |
Microalbuminuria | 3-30 | 30-300 mg / day | ||
Proteinuria | 30-300 | 300-3000 mg / day | 50-300 | 500 mg-3 g / day |
Nephrotic proteinuria | > 300 | > 3 g / day | > 300 | > 3 g / day |
All kidney diseases may present with degrees of proteinuria. If proteinuria in nephrotic range (> 3 g / day) one can say with certainty that filtrasjonsbarrieren damaged and that there is a glomerular disease. If nephrotic proteinuria occurs with low see albumin (<30 g / l) and edema We denote the condition nephrotic syndrome which is a clear indication of renal biopsy.
If the patient presents with a kidney disease in which large proteinuria dominate the clinical picture, we say often that kidney disease presents itself nephrotic even if the patient does not fulfill all the criteria for nephrotic syndrome. The various glomerulonephritis tends clinically presenting itself either nephrotic or nephritic, which helps to substantiate the diagnosis before biopsy answer finally exists.
Proteinuria is an important diagnostic tool for finding patients with kidney disease. In addition, the degree of proteinuria an important prognostic marker for the progression of kidney disease. Regular monitoring of proteinuria is therefore essential when recruiting medical issues.
