About test
What does Anti Streptolysin O Titres ASO-Titers measure?
The ASO titre test measures antibodies against streptolysin O, a toxin produced by group A Streptococcus bacteria. It may help indicate a recent streptococcal infection, particularly when evaluating possible complications such as rheumatic fever or certain kidney inflammation conditions. ASO levels are interpreted along with symptoms, medical history, examination findings, and other laboratory tests, as they may remain elevated after an infection has resolved.
