Sample Required:

The normal range for ASO levels can vary depending on the specific laboratory and testing methods used. It’s important to consult with your healthcare provider for the interpretation of your specific test results.
What is the test?
The Anti-Streptolysin O (ASO) test is a blood test that measures the levels of antibodies called anti-streptolysin O in the bloodstream. These antibodies are produced by the immune system in response to a previous infection by the bacterium Streptococcus pyogenes, which can cause conditions such as strep throat and certain post-infectious complications.
Test Procedure:
During the ASO test, a healthcare professional will collect a blood sample from your arm using a needle. The blood sample is then sent to a laboratory for analysis. In the laboratory, the sample is tested for the presence and level of anti-streptolysin O antibodies.
When to take the test:
The ASO test is typically performed when a healthcare provider suspects a recent or past Streptococcus pyogenes infection. It may be ordered to confirm a diagnosis of certain streptococcal infections or to monitor the response to treatment. The test is usually performed several weeks after the initial infection, as it takes time for the antibody levels to rise.
Who should take this test:
The ASO test is commonly ordered for individuals who have had symptoms of a Streptococcus pyogenes infection, such as sore throat, fever, or skin infections. It may also be performed if there are concerns about post-infectious complications, such as rheumatic fever or glomerulonephritis. Your healthcare provider will determine if this test is appropriate based on your specific symptoms and medical history.
Precautions for exceptional cases (pregnancy, etc.):
For pregnant women or individuals with specific medical conditions, additional considerations and specific blood tests may be recommended. It is important to inform your healthcare provider about any specific medical conditions, medications, or pregnancy before undergoing the ASO test.
