What serologic tests should be done to diagnose SAAG?
There are no tests similar to the streptozyme analysis for the diagnosis of staphylococcal infections.
The key to diagnosis is to document by blood, urine, sputum, or aspiration sample a positive culture for staphylococcal infection in the setting of acute glomerulonephritis.
The activation of the complement pathway is present in 82% of cases, with the alternate pathway (low C3) being the most common, but activation of the classic pathway (low C3 and C4) can also be found.
