What is this test?
The Coxsackievirus A10 antibody test is a blood test that detects whether your immune system has produced antibodies against Coxsackievirus A10, a type of enterovirus. This virus can infect the heart muscle and surrounding tissues, leading to conditions such as myocarditis (inflammation of the heart muscle) or pericarditis (inflammation of the heart's outer lining).
Why is this test performed?
This test is primarily used to help diagnose heart infections caused by Coxsackievirus A10. If you have symptoms such as chest pain, shortness of breath, fatigue, or irregular heartbeat, your doctor may order this test to determine if a viral infection is the cause. It can also be used to monitor the progression of infection or the effectiveness of treatment.
What do the results mean?
The test measures antibody levels (titers) in your blood. A positive result indicates that you have been infected with Coxsackievirus A10 at some point. The antibody titer level can help your doctor determine whether the infection is recent (high titers often indicate recent infection) or past. Your doctor will interpret these results in combination with your symptoms and other test findings.
How is the test done?
A healthcare professional will draw a small blood sample from a vein in your arm. The sample is then sent to a laboratory for analysis. You may experience slight discomfort or bruising at the puncture site, but serious complications are rare.
Reference range
Negative: <1:40; Equivocal: 1:40-1:80; Positive: ≥1:160 (significant for recent or past infection)N/A
No special preparation required. Standard serum collection. Patient may eat and drink normally before specimen collection.
