|Description :||Streptolysin is a hemolysin produced by group A streptococci. In an infected individual streptolysin O acts as a protein antigen, and the patient mounts an antibody response. A rise in anti-streptolysin O level begins about 1 week after infection and peaks 2-3 weeks later. In the absence of complications or reinfection, the anti-streptolysin O ASO titer will usually fall to preinfection levels within 6-12 months. Both clinical and laboratory findings should be correlated in reaching a diagnosis.|
