Anti-Streptolysin O (ASO)

The ASO (WHO) assay is intended for the quantitative determination of antibody to streptolysin O by immunoturbidimetric assay. The streptolysin O antigen used in this kit is purified from streptococci culture. The anti-streptolysin O in the serum sample interacts with the streptolysin O antigen forming immune complexes. The immune complexes cause an increase in light scattering that correlates with the concentration of serum anti-streptolysin O.
