Hepatitis A Serology
April 24th, 2019
Overview
Most hepatitis A assays measure both IgM and IgG levels.
Hepatitis A IgM is detectable at the time of symptom onset, after an incubation period of 14-28 days.
Hepatitis A IgG develops later and persists for a long period of time, and its presence is indicative of vaccination or past infection.
