West Nile Virus (horse) – Antibodies (IgG and IgM)

serum 1 ml

ELISA (Flaviviruses IgG und West Nile Virus IgM)

2 - 3 days

The flavivirus IgG ELISA detects a broad spectrum of flaviviruses such as West Nile virus, Usutu virus, TBE virus etc. due to the high cross reactivity within the flavivirus antibodies. Positive IgG antibodies thus indicate flavivirus-specific antibodies. Further differentiation into antibodies specific for West Nile virus is not possible with the ELISA method. For positive IgM results, further differentiation using virus neutralisation tests (VNT) is therefore advisable. The detection of IgM antibodies is notifiable in many countries and indicates a recent infection.
