Laboratory Findings
Initial Evaluation
- Assess all patients with biopsy-proven IgA nephropathy for secondary causes to rule out common causes of secondary IgA nephropathy
- Viral serologies: HIV, HBV, HCV
- Liver function tests
- Electrophoresis of serum immunoglobulins
- Assess the risk of progression and prognosis by the following parameters at diagnosis and at follow-up:
- Blood pressure measurement
- Serum creatinine to estimate glomerular filtration rate (GFR)
- Proteinuria
- Pathological features
A kidney biopsy is to be considered only if signs of AKI and macroscopic hematuria persist for at least 5 days since onset of kidney injury.
