Antistreptolysin O (ASO) Test

The ASO latex reagent test kit is used to determine the content of Anti-Streptolysin"O" (ASO) in human blood, and a specific reagent for the specific protein analyzer applies only to the clinical in vitro assisted diagnosis. Streptolysin "O" is one of the metabolites of group A hemolytic streptococcus, a hemolytic activity of the protein, highly immunogenic. Hemolytic streptococcus group A in the human body exists as normal flora. The ASO has certain basic values in the normal human body. ASO increased after Hemolytic streptococcus infected. Therefore, ASO has become an important indicator to determine the streptococcal infection. Patients with Hypercholesterolemia or macroglobulinemia may also appear to have the ASO elevated.

Testing Principle of Antistreptolysin O (ASO) Test

  • The ASO units conjugated Anti-Streptolysin"O" (ASO) in the latex surface.

  • ASO in the sample and the antibody become immune complexes by Latex condensation reaction.

  • The immune complexes will produce the phenomenon of light scattering, which is proportional to the intensity of scattered light and samples of ASO levels.

  • Using a specific protein analyzer to measure the intensity of scattered light, the concentration of ASO is determined by comparing the turbidity of samples to the standard concentration.
