what blood test for lyme disease
CDC currently recommends a two-step process when testing blood for evidence of antibodies against the Lyme disease bacteria. Both steps can be done using the same blood sample. The first step uses a testing procedure called âEIAâ (enzyme immunoassay) or rarely, an âIFAâ (indirect immunofluorescence assay).DC currently recommends a two-step process when testing blood for evidence of antibodies against the Lyme disease bacteria.
