Coxsackie B (also written coxsackievirus B) is a type of enterovirus. There are several different serotypes of Coxsackie B known to infect humans.

In the United States, ARUP Laboratories offers a serum microneutralization assay that is designed to measure the concentration of serum antibodies to six serotypes of the virus; B1 through B6. This specific assay has been shown to be sensitive for detection of chronic infections in ME patients. A persistent fourfold or greater rise in antibody titer is often found in these patients, which is not often found in healthy controls.

A complement fixation assay for Coxsackie B serotypes is available in the United States from LabCorp and Quest Diagnostics, however this specific type of assay has not been found to be sensitive for the chronic infections found in ME patients due to the lack of virus present in the blood, resulting in a false negative.

Research has shown that many patients with ME have persistently elevated levels of Coxsackie B IgM or IgG antibodies as well as circulating immune complexes containing viral antigen, indicating the possible presence of a chronic infection. Elevated Coxsackie B antibodies have been found in patients in at least one ME outbreak.[1]
