Product details.
Intended use: ASO Turbilatex is a quantitative latex turbidimetric test for anti-streptolysin O (ASO) in human serum or plasma. Latex particles coated with streptolysin O agglutinate with the ASO in the sample, and the change in absorbance is compared with a calibrator of known ASO concentration. Manufactured at Reckon’s Vadodara facility under ISO 13485:2016 quality management, and released against reference standards before dispatch.

Procedure at a glance4 steps
- Mix 0.9 ml of diluent (R1) with 0.1 ml of latex (R2) as the working reagent; the calibrator is ready to use.
- Add 10 µl of calibrator or sample to 1.0 ml of working reagent and mix.
- Read the absorbance at 540 nm immediately (A1) and again after 2 minutes (A2).
- ASO (IU/ml) = (A2 − A1) of sample ÷ (A2 − A1) of calibrator × calibrator concentration.
