Antistreptolysin O (ASO)

ASO-LTFor In Vitro Diagnostic Use

Intended Use

ASO-LT is an in vitro assay for the quantitative determination of antistreptolysin O (ASO) titer in serum.


Latex immunoassay

Special Characteristics

ASO-LT based on Latex immunoassay method is not interfered significantly by other serum components. The measurable range without dilution of samples is 2.1-1000 IU/mL.

Principle of the Method

When a sample is mixed with Buffer and Latex Reagent, ASO in the sample combines specifically with the latex sensitized with streptolysin O in the Latex Reagent to yield an insoluble aggregate which causes increased turbidity in the solution. The degree of turbidity of solution can be measured optically and is proportional to the concentration of ASO in the patient's sample.
