n.
A molecule that is capable of binding to an antibody or to an antigen receptor on a T cell, especially one that induces an immune response. An antigen is usually a foreign substance, such as a toxin or a component of a virus, bacterium, or parasite.

HBsAg, anti-HBs, anti-HCV, anti-HIV levels were determined using the chemiluminescence enzyme immunoassay method (Architect, Abbott Laboratories, USA).
The hepatitis B surface antigen (HBsAg) in serum is the first sero-marker to indicate active HBV infection, either acute or chronic.
Hepatitis B surface antigen (HBsAg) can be detected in 25-61% of patients with DLBCL and 20-40% of those with FL.[4] Rituximab plus chemotherapy (R-chemo) is the standard first-line treatment for patients with DLBCL or FL, with several randomized clinical trials (RCTs) having demonstrated its benefits.[5],[6],[7],[8],[9],[10] Reactivation of HBV is a well-established complication of R-chemo and can result in hepatic mortality and interruptions in chemotherapy.[11],[12]
Programs performed HBV screening by testing for HBsAg; persons whose test results were positive received a second HBsAg test 6 months later to confirm chronic HBV infection.
The test results were given to the clinicians who are working on ANC clinic of the hospital and all women who tested positive for HBsAg were counseled on their status, the route of disease transmission, the need for immunization to their neonate at birth, and close-contact screening against hepatitis.
Serum HBsAg levels were measured using Roche Elecsys HBsAg II quant assay (range 0.05-52000 IU/mL, Roche Diagnostics, Mannheim, Germany).
While there is no clinical cure for chronic HBV infection, a functional cure can be achieved, and this is defined as the suppression or elimination of HBV DNA with HBsAg loss and appearance of antibodies to HBsAg.
* Infants weighing at least 2,000 g and born to mothers who are HBsAg negative: Administer the hepatitis B vaccine within 24 hours of birth.
