The SPP is useful in diagnosing dysgammaglobulinemias, iron deficiency, idiopathic nephrotic syndrome of childhood, active systemic lupus erythematosus and hypocomplementemic glomerulonephritides. The profile also aids in the assessment of the status of the immune system in patients receiving chemotherapy and may be abnormal in the presence of viral infections, the IgA nephropathies and acute and chronic inflammation. A nephrologist interprets all SPPs.
Specimen requirements 1 mL Serum, frozen; MAB-Urine requires 1 mL urine.
