ARCHITECT HAVAB-M Reagent
A chemiluminescent microparticle immunoassay (CMIA) for the qualitative detection of IgM antibody to hepatitis A virus (IgM anti-HAV) in human adult and pediatric serum and plasma (dipotassium EDTA, lithium heparin, and sodium heparin) and neonatal serum.
There is a potential to generate a false grayzone or reactive HAVAB-M result when the ARCHITECT AUSAB assay precedes the ARCHITECT HAVAB-M assay.
