Human Leukocyte Antigen (HLA) B27 (subtypes B*2701-2759) is a class I surface antigen encoded by the B locus in the major histocompatibility complex (MHC) on chromosome 6 and presents antigenic peptides (derived from self and non-self antigens) to T cells.or example, while 90% of people with ankylosing spondylitis (AS) are HLA-B27 positive, only a fraction of people with HLA-B27 ever develop AS. Individuals who are HLA-B27 positive are more likely to experience early onset AS than HLA-B27 negative individuals.
1 Hepatitis B e-antigen (HBeAg) is an HBV protein that is only present during an active HBV infection. 2  This test determines how contagious you are. 3  Testing for this antigen can also be used to monitor the effectiveness of treatment for HBV. 4  HBV DNA testing checks for genetic material (DNA) from the hepatitis B virus. The presence of HBV antibodies means that you have been exposed to the hepatitis B virus at some time. 2  But you could have been infected long ago and gotten better, or you may have a current infection. 3  Genetic material (DNA) of the hepatitis B virus shows that the virus is in the body.
