Introduction
A positive result for items 1 and 5 in the hepatitis B panel means that both the hepatitis B surface antigen (HBsAg) and the hepatitis B core antibody (anti-HBc) are positive. This pattern—positive for the first item (HBsAg) and the fifth item (anti-HBc)—indicates that the individual has been infected with the hepatitis B virus, consistent with a diagnosis of "minor two-positive" hepatitis B.
HBsAg and anti-HBc positive (referred to as "1.5 positive") in the five-item hepatitis B panel means that hepatitis B surface antigen and hepatitis B core antibody test positive during testing.
The five-item hepatitis B panel includes: hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), hepatitis B e antigen (HBeAg), hepatitis B e antibody (anti-HBe), and hepatitis B core antibody (anti-HBc). A "1.5 positive" result indicates that both the first item (HBsAg) and the fifth item (anti-HBc) are positive, suggesting that the body has been infected with the hepatitis B virus. This usually indicates a past or existing hepatitis B infection, commonly known as "minor two positive" (a milder form of chronic hepatitis B).
If abnormalities are found in the five-item hepatitis B test, further examinations such as liver function tests and color ultrasound are recommended to assess the severity of the condition and guide targeted treatment. In daily life, preventive measures should be taken to avoid transmitting the virus to others.
