Intended Use:

ASO Turbilatex Test for estimation of antibodies against Streptolysin ‘’O ‘’ by using Latex turbidmertric method.


Streptolysin “O” is a toxic immunogenic exoenzyme produced by haemolytic Streptococci of groups A, C and G. Measuring the ASO antibodies are useful for the diagnostic of rheumatoid fever, acute glomerulonephritis and streptococcal infection. Rheumatic fever is an inflammatory disease affecting connective tissue from several parts of human body as skin, heart, joints etc. and acute glomerulonephritis is a renal infection that affects mainly to renal glomerulus.

ASO Turbilatex Test Kit


The ASO-Turbilatex is a quantitative turbidimetric test for the detection of anti-steptolysin “O” (ASO) antibodies in human serum/plasma. Latex particles coated with steptolysin “O” are agglutinated when mixed with samples containing ASO. The agglutination causes an absorbance change, dependent upon the ASO contents of the patient sample that can be quantified by comparison from a calibrator of known ASO concentration.
