Answer

Assess renal function in patients with proteinuria or hematuria by a 24-hour creatinine clearance test. Alternatively, the glomerular filtration rate (GFR) can be estimated using the Modification of Diet in Renal Disease (MDRD) formula or CKD-EPI

Although the serum IgA level is elevated in up to half of patients, this finding is insensitive, nonspecific, and of no clinical utility

Diagnosis of IgA nephropathy should be confirmed by renal biopsy.
