ASO and anti-DNase B are the most common of several antibodies that are produced by the bodys immune system in response to a strep infection with group A Streptococcus.

Serum anti-streptolysin O ASO titres and anti-streptococcal DNAase antibody estimations can indicate a recent streptococcal infection in patients with a suspect reactive arthritis. A rise in ASO begins about one week after infection and peaks two to four weeks later. ASO levels do not rise with cutaneous infections.

Levels peak 3 to 6 weeks after infection. Its not used to diagnose a current strep infection. The antibodies work against a substance made by the bacteria called streptolysin O.

Antistreptolysin O ASO is an antibody. The most commonly employed test measures antibodies to antistreptolysin O. ASO is one of several types of antibodies produced by the immune system in response to infection with A Streptococcus Bacteria.

Whenever there is any strep infection antibodies are produced in the blood testing which can give a clear idea about the infection. Principle of the Test. ASO and anti-DNase B are the most common of several antibodies that are produced by the bodys immune system in response to a strep infection with group A.

In the absence of complications or reinfection the ASO titer will usually fall to preinfection levels.

In an infected individual streptolysin O acts as a protein antigen and the patient mounts an antibody response. Confirm a prior infection with group A Streptococcus in patients suspected of having a nonsuppurative complication such as acute glomerulonephritis AGN or acute rheumatic fever ARF.
