Coxsackievirus A9 Antibodies details
What Coxsackievirus A9 Antibodies shows
Coxsackievirus A9 is one of the coxsackie A enteroviruses, a group spread by contact with saliva, respiratory droplets or stool. It can cause fever, rashes, respiratory illness and, less often, viral meningitis. This test measures antibodies to the virus in your blood. A positive result shows that your immune system has met the virus at some point, but antibodies can persist long after infection and different enteroviruses cross-react. A rising level between two samples taken a few weeks apart is more informative than a single result. Results are interpreted alongside your symptoms and, often, direct virus testing.
Tests that include Coxsackievirus A9 Antibodies
Panel currently includes testing against A-2, 4, 7, 9, 10, and 16 antigens. Although there is cross-reactivity among the enteroviruses by CF, most healthy people do not have titers >1:8. Therefore, detectable titers, especially those >1:32, should be considered diagnostic. Confirmed serodiagnosis is made by demonstration of a four-fold change in titers between acute and convalescent sera.
