HBcAb

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.

HBsAb test, also known as the Hepatitis B surface antibody test, looks for antibodies against the Hepatitis B virus in the blood. This test helps figure out if there’s immunity to Hepatitis B, either from getting vaccinated or from a past infection. When the body makes antibodies, it means it’s responded to the virus in some way, giving protection against future infections. This test is especially useful for telling if the Hepatitis B vaccine worked or if there was an infection and developed immunity. Getting this test done is simple – it just needs a small blood sample. Knowing the status of Hepatitis B antibodies can be really important in staying on top of health and stopping the spread of this virus that affects the liver.

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.
