While there was a significant decrease in HBsAb concentration with increasing age (P < 0.
There have however been reports of clinically significant HBV infection in previously immunised dialysis patients in whom production of HBsAb was no longer measurable [1].

Immunization with HBsAg free archaeosomes did not elicit significant HBsAb in comparison to the negative control group.
HBsAb, HBsAg, HBeAg were run before running each batch of samples.
Only the extremely rare combination of HBsAg and HBsAb together, without HBcAb, which occurred in 12 of the 39 774 specimens (a frequency of 0.
Acutely infected patients who do not develop chronic hepatitis B will become hepatitis B surface antigen (HBsAg)-negative, hepatitis B core antibody (HBcAb)-positive, and HBsAb (anti-HBs)-positive.
All internationally adopted children should be screened for hepatitis B serologic testing, including hepatitis B surface antigen (HBSAg), core antibody (HBcoreAb), and surface antibody (HBSAb), at the time of arrival and 6 months later, which can help to distinguish between infection (presence of HBSAg) and immunity to hepatitis B (presence of HBSAb alone) (Barnett, 2005; Staat & Klepser, 2006).
Both serum HBsAg and HBsAb should be measured in elderly patients as there is increasing evidence that patients with HBcAb alone have chronic Hepatitis B infection as indicated by detectable HBV DNA in the liver [16].
The HBV markers (HBsAg, HBsAb, HBeAg, HBeAb, HBcAb, and anti-HBc Ab IgM) were measured using the enzyme-linked immunosorbent assay (ELISA) kits (Roche Laboratories, Branchburg, NJ, USA).
