Test Result: A test sample is considered to contain ASO antibodies in excess of 200 IU/ml when agglutination (clumping) is observed when compared to the result of the negative control. The test principle, procedure and interpretation presented here are based on Latex Anti-Streptolysin O (ASO) test. The presence of Anti streptolysin O antibodies in serum can be indicated by seeing the ability of serum to neutralize the hemolytic activity of streptolysin O reagent (antigen).
Rapid Urease Test: Also known as the CLO test (Campylobacter-like organism test), is a rapid test for diagnosis of Helicobacter pylori. The basis of the test is the ability of H. pylori to secrete the urease enzyme, which catalyzes the conversion of urea to ammonia and bicarbonate. Urea is waste product excreted in urine by animals.
