ANTI-STREPTOLYSIN O ANTIBODY (ASO)

The Anti-Streptolysin O (ASO) antibody test helps detect a recent infection with Group A Streptococcus, the bacteria responsible for illnesses like Strep throat and Scarlet fever. Elevated ASO levels may indicate the body’s immune response to a recent strep infection and can help evaluate potential complications such as Rheumatic fever or Post‑streptococcal glomerulonephritis. This simple blood test provides valuable insight for patients experiencing symptoms like joint pain, fever, rash, or inflammation following a suspected strep infection. Early detection helps guide appropriate follow-up care and treatment.
