What is this test?
The Coxsackievirus B5 antibody test is a blood test that detects whether your body has produced antibodies against Coxsackievirus B5. This virus is part of a group of viruses that can cause infections ranging from mild cold-like symptoms to more serious conditions affecting the heart muscle.
Why is it ordered?
This test is often ordered when you have symptoms of a heart infection (like myocarditis or pericarditis), such as chest pain, shortness of breath, fatigue, or irregular heartbeat, especially after a recent viral illness. It helps doctors determine if a viral infection may be causing your heart symptoms.
How is the test done?
A healthcare professional will draw a small blood sample from a vein in your arm. The sample is sent to a laboratory where it is tested for the presence and level of antibodies (IgM and IgG) against Coxsackievirus B5.
What do the results mean?
A positive result means your body has produced antibodies against Coxsackievirus B5, indicating a recent or past infection. A four-fold increase in antibody levels between two samples taken 2-4 weeks apart is typically considered evidence of a recent infection. Your doctor will interpret these results along with your symptoms and other test findings.
Reference range
Negative: <1:8 titer; Equivocal: 1:8-1:16 titer; Positive: >1:16 titer. Titers ≥1:32 indicate recent or past infection. Clinical correlation recommended.N/A
No special preparation required. This is the first specimen in a series for seroconversion diagnosis. A convalescent specimen collected 2-4 weeks later is typically recommended for comparison.
