Small e-antigen negative

Small e-antigen negative

"Small three positives," or hepatitis B "small three positives," refers to a state where serological tests for hepatitis B virus "two pairs and a half" show positive results for hepatitis B surface antigen (HBsAg), hepatitis B e-antibody (anti-HBe), and hepatitis B core antibody (anti-HBc). Clinically, "small three positives" generally indicate two possibilities: one suggests that hepatitis B virus replication is suppressed, which is a sign of good prognosis; the other possibility is that the hepatitis B virus has mutated, remaining infectious and potentially causing liver function damage.

Acquired Immunodeficiency Syndrome (AIDS) is a systemic disease caused by infection with the Human Immunodeficiency Virus (HIV). HIV attacks the human immune system, and infected individuals gradually lose their ability to fight off diseases, eventually dying from severe infections and malignant tumors in the late stages.
