What is the test?
This test measures the level of antibodies against streptolysin O, a toxin produced by streptococcal bacteria. Elevated levels suggest recent streptococcal infection.
Test Procedure:
A blood sample is drawn from a vein, and the level of ASO antibodies is measured in the laboratory.
When to take the test:
When a healthcare provider suspects recent streptococcal infection, especially in cases of symptoms like sore throat, fever, or joint pain.

Pregnant individuals should inform their healthcare provider about their pregnancy status, as it may affect the interpretation of test results.
Frequently Asked Questions (FAQs) for ASO (Antistreptolysin O) Titre Test:
Q1: How long does it take for ASO levels to rise after a streptococcal infection?
A: ASO levels typically rise about one to three weeks after a streptococcal infection.
Q2: Can ASO levels remain elevated after the infection has cleared?
A: Yes, ASO levels can stay elevated for a few months even after the infection has resolved.
Q3: Is a high ASO level indicative of a current streptococcal infection?
A: Not necessarily. Elevated levels indicate past exposure or recent infection but may not signify a current infection.
Q4: Can antibiotics affect ASO test results?
A: Yes, antibiotics taken before the test may lower ASO levels, potentially affecting the accuracy of results.
Q5: Can lifestyle changes impact ASO levels?
A: Lifestyle changes may not directly affect ASO levels, but maintaining overall health can support the body’s immune system.
