This study tested a new blood test (mu-antibody-capture ELISA) to detect recent Coxsackie B virus infections by looking for IgM antibodies, which indicate fresh infection. Researchers tested 760 patients with various conditions including chest pain, heart inflammation, and myalgic encephalomyelitis (ME), plus 304 healthy controls, and found that this IgM test could reliably identify recent Coxsackie B infections without the confusion caused by old antibodies from past infections.
