What is the principle of Antistreptolysin O?

Principle. The detection of anti-streptolysin O antibodies is based upon the neutralization of the streptolysin O hemolytic activity by antibodies present in the test serum. The antigen-antibody immunological complexes that are formed are revealed by the addition of a suspension of sheep erythrocytes.

What Antistreptolysin means?

The antistreptolysin O (ASO) titer test is a blood test that checks for a strep infection. When you come into contact with harmful bacteria, your body produces antibodies to defend itself against these bacteria. Your body produces antibodies specific to the bacteria they fight.

What is an Antistreptolysin O test used to detect?

The ASO test is primarily used to help determine whether a recent strep infection with group A Streptococcus: Is the cause of a person’s or glomerulonephritis, a form of kidney disease. Caused rheumatic fever in a person with signs and symptoms.

What is the significance of the Antistreptolysin O antibody finding?

An antistreptolysin O titer (ASO) is a blood test used to determine if you’ve had a recent infection caused by group A streptococcus bacteria. It’s not used to diagnose a current strep infection, such as strep throat.

What is ASO slide test?

The ASI ASO Slide Test is a latex slide agglutination assay for the qualitative and the semiquantitative detection of Antistreptolysin-O (ASO) antibodies in human serum. No initial dilution of patient samples is required for this test.

What is the full form of Aso?

Assistant Section Officer (ASO) is an assistant to a Section Officer (SO), an officer in charge of a section in the Department.

What is ASO test for?

Antistreptolysin O (ASO) titer is a blood test to measure antibodies against streptolysin O, a substance produced by group A streptococcus bacteria. Antibodies are proteins our bodies produce when they detect harmful substances, such as bacteria.

How do you treat ASO?

Increased levels of ASO titre in the blood could cause damage to the heart and joints. In most cases, penicillin is used to treat patients with increased levels of ASO titre.

Why is it called Streptolysin O?

The “O” in the name stands for oxygen-labile; the other related toxin being oxygen-stable streptolysin-S. The main function of streptolysin O is to cause hemolysis (the breaking open of red blood cells)—in particular, beta-hemolysis.
