Key facts

Hantavirus IgM Ab [Presence] in Serum or Plasma by Immunofluorescence

Hantavirus Ab.IgM

Detection of IgM antibodies against Hantavirus serotypes in serum or plasma based on immunofluorescent patterns to assist in the diagnosis of hantavirus infections. The term was created for, but not limited in use to, the submitter's test kit, EUROIMMUN indirect immunofluorescence test for Hantavirus, which detects but does not differentiate between IgM antibodies against the following Hantavirus serotypesHantaan (HTNV), Sin Nombre (SNV), Puumala (PUUV), Dobrava (DOBV), Seoul (SEOV), and Saaremaa (SAAV).
