differance between HAV antibodies and HAV IgM
Jan 13, 2013

Can u explain tha differance between HAV antibodies and HAV IgM and also expalin if HAV antiboy is positive and HAV IgM is negative How?

Response from Dr. Taylor

The total antibody tells us if a person has been exposed to hepatitis A and if a person has had hepatitis A but does not tell us when this infection existed. The IgM tells us if the infection is current/recent.

The HAV antibody is positive and HAV IgM negative when the hepatitis A infection is not a current or recent infection but was present in the past.

Hepatitis A goes away on its own after the acute/active illness, and does not remain as an ongoing, chronic infection. No medications to treat the virus specifically are needed. Typically there is no long-term damage to the liver.
