Hepatitis B surface antigen with an upward arrow indicates that Hepatitis B surface antigen exceeds the normal value and is Hepatitis B positive. Hepatitis B surface antigen, Hepatitis B e antigen, and Hepatitis B core antibody data are also needed to determine whether it is Hepatitis B major or Hepatitis B minor. HBV-DNA, liver function, blood test and other tests can also be improved to determine the hepatitis B virus infection. Hepatitis B surface antigen with an arrow pointing upwards means that the normal value of Hepatitis B surface antigen is greater than 0.18ng/ml. It means that the Hepatitis B surface antigen is positive, and a positive Hepatitis B surface antigen means that a person is a carrier of Hepatitis B virus. Hepatitis B e antigen and Hepatitis B core antibody will also be tested at the same time, and the patient can be judged as Hepatitis B major triple positive or Hepatitis B minor triple positive according to these three data. The difference between Minor Triple Positive and Major Triple Positive is that Major Triple Positive is e antigen positive and e antibody negative, while Minor Triple Positive is e antigen negative and e antibody positive. HBV-DNA can also be perfected to quantify the amount of hepatitis B virus. Or liver function and blood tests may be performed to detect the severity of the patient’s condition.
