Test Result: A test sample is considered to contain ASO antibodies in excess of 200 IU/ml when agglutination (clumping) is observed when compared to the result of the negative control. The test principle, procedure and interpretation presented here are based on Latex Anti-Streptolysin O (ASO) test. The presence of Anti streptolysin O antibodies in serum can be indicated by seeing the ability of serum to neutralize the hemolytic activity of streptolysin O reagent (antigen).
Antistreptolysin O (ASO) is an antibody targeted against streptolysin O, a toxic enzyme produced by group A Streptococcus bacteria. ASO and anti-DNase B are the most common of several antibodies that are produced by the body's immune system in response to a strep infection with group A Streptococcus. This test measures the amount of ASO in the blood. Group A Streptococcus (Streptococcus pyogenes) is the bacterium responsible for causing strep throat and a variety of other infections, including skin infections (pyoderma, impetigo, cellulitis).
