Shop - Anti Streptolysin (ASO) – Quantitative

The Anti-Streptolysin O (ASO) quantitative test measures the level of antibodies against streptolysin O, a toxin produced by the streptococcus bacteria. This test is primarily used to assess recent streptococcal infections, such as strep throat or rheumatic fever. Elevated ASO levels may indicate a previous infection, typically occurring 1-3 weeks after the onset of symptoms. The quantitative nature of the test helps evaluate the severity of the immune response and can assist in monitoring the course of the infection. A blood sample is required for this test, and results are interpreted alongside clinical findings and other diagnostic tests to guide treatment decisions.
