High virus titer
Viral load, also known as viral burden, is a numerical expression of the quantity of virus in a given volume of fluid, including biological and environmental specimens. It is not to be confused with viral titre or viral titer, which depends on the assay. When an assay for measuring the infective virus particle is done (Plaque assay, Focus assay), viral titre often refers to the concentration of infectious viral particles, which is different from the total viral particles. Viral load is measured u… WebFeb 7, 2024 · The titer will also likely look at IgM anti-HBc, which is a subclass of anti-HBc. Positive results for IgM anti-HBc indicate an active infection within the past 6 months. …
