The Antistreptolysin O (ASO) blood test is used to measure the level of antibodies called antistreptolysin O in the blood. These antibodies are produced in response to a Streptococcus infection, specifically caused by Group A Streptococcus bacteria.
Sample Type: The test requires a small blood sample, typically obtained by drawing blood from a vein in your arm using a needle.
Normal Range: The normal range for ASO levels can vary depending on the specific laboratory and the reference values they use. Generally, the normal range is less than 200 international units per milliliter (IU/mL).
The ASO blood test is primarily used to help diagnose a recent or past Streptococcus infection, such as strep throat or certain complications caused by Group A Streptococcus bacteria, including rheumatic fever and glomerulonephritis.
When a person is infected with Group A Streptococcus, their immune system produces antibodies, including antistreptolysin O, to fight the infection. The ASO test measures the level of these antibodies in the blood. Elevated levels of ASO can indicate recent or ongoing infection.
It’s important to note that the ASO test is not used to diagnose an active infection, as the levels of ASO antibodies may take several weeks to rise after an infection and can remain elevated for an extended period even after the infection has resolved.
The interpretation of ASO test results should be done in conjunction with other clinical findings, such as symptoms and physical examination. If you have concerns about a possible Streptococcus infection or related complications, it’s recommended to consult with a healthcare professional for proper interpretation of your ASO test results and to discuss any necessary steps or treatments based on the findings.
