Coxsackie A Antibodies (Serotypes 2, 4, 7, 9, 10 and 16), Serum
Also known as: COX A AB
Use
This test is used to detect the presence of antibodies against Coxsackie A virus serotypes 2, 4, 7, 9, 10, and 16 in the serum. These serotypes are commonly associated with hand, foot, and mouth disease and other enterovirus-related illnesses. The presence of antibodies can indicate a past or recent infection, with higher antibody titers suggesting recent infection.
Special Instructions
Not provided.
Limitations
Cross-reactivity can occur among enteroviruses, which means antibodies to non-target serotypes may be detected. Antibody levels may persist for only a few months, limiting the test's ability to detect past infections. Titers of 1:8 or 1:16 are not definitive for recent infection but suggest a possible past infection. A four-fold increase in titer between acute and convalescent samples confirms diagnosis.
