Specific Proteins - Anti-Streptolysin O (ASO)

The Anti-Streptolysin (ASO) test is used to determine recent streptococcal infection and post streptococcal complications which includes rheumatic fever and glomerulonephritis. The presence and level of ASO antibodies in human serum directly reflects the extent and degree of infection. Elevated levels of ASO may also be present in other conditions including scarlet fever, acute rheumatoid arthritis, tonsillitis and various other streptococcal infections as well as in health carriers.

The Randox Anti-Streptolysin (ASO) assay is used to measure the presence of anti-streptolysin antibodies in the blood to determine if a strep infection is present.
