The five hepatitis B tests are commonly used to check hepatitis B. The difference between positive items 2, 4 and 5 of the five hepatitis B tests, and positive items 2 and 5, lies mainly in item 4, hepatitis B e antibody. Whether this item is positive or not is generally of no separate distinguishing significance for this condition, as items 2 and 5 are already able to determine the patient’s status. A positive hepatitis B core antibody in item 5 indicates that the body has indeed been exposed to the hepatitis B virus, that is, has been infected by the hepatitis B virus, and therefore will produce antibodies. Item 2 hepatitis B surface antibody is a protective antibody, and obtaining this surface antibody indicates that one has immunity and is generally not a hepatitis B patient. Therefore, the difference between 2, 4 and 5 positive and 2 and 5 positive is actually not much. This condition may also be occult hepatitis B. If the DNA quantification of the hepatitis B virus is checked, using a particularly sensitive method, it is possible for a certain percentage of people to be detected.
