HBsAb

Hepatitis A virus is one of the most common causes of liver inflammation. Your immune system makes antibodies when you are first infected with HAV. IgM Antibodies often begin to appear in the blood 5 to 10 days before symptoms appear. They can stay in your blood for about six months after the infection. Some antibodies called IgG can last in your blood for life.

The quantitative test of hepatitis B core antibody level distinguishes cases of hepatitis antibodies from vaccination with those with a history of cured acute hepatitis B. This test can also be used with other hepatitis immunological indicators to evaluate treatment effectiveness in hepatitis B patients.

The hepatitis B virus (HBV) is one of the major causes of liver inflammation. The hepatitis B e antigen (HBeAg) appears after an HBV infection. Usually, HBeAg indicates much higher rates of viral replication and enhanced infectivity. However, variants of the hepatitis B virus do not produce the ‘e’ antigen, so this rule does not always hold. The HBeAg may be cleared, and antibodies to the ‘e’ antigen (anti-HBe) will arise immediately afterward, suggesting a dramatic decline in viral replication.
