Citrulline is a non-standard amino acid, as it is not incorporated into proteins synthesis. Cyclic citrullinated peptide were equally specific for RA, but with a higher sensitivity with linear pept...

Anti-double stranded DNA antibody (anti-dsDNA) is one of a group of autoantibodies called antinuclear antibodies (ANA). Normally, antibodies protect against infection, but autoantibodies are produc...

Anti-HAV IgG implies past infection with hepatitis A virus (HAV) or vaccination against HAV.

Hepatitis A is a self-limiting disease and is often a subclinical disorder. During the acute phase of HAV infection, IgM anti-HAV appears in the pateint's serum and is nearly always detectable at t...

Viral specific IgM antibody has been detected in most acute viral infections and is a reliable marker of acute disease. The concentrations of anti-HBc IgM rise rapidly in patients with acute infect...

Anti-HBe is found in association with hepatitis B viral infection. Seroconversion from HBeAg to anti-HBe during acute hepatitis B infection is usually indicative of resolution of infection and a re...

Anti-HBs are often used to monitor the success of Hepatitis B vaccination. The presence of anti-HBs has been shown to be important in protection against Hepatitis B virus (HBV) infection. Anti-HBs ...
