The symptoms described by the patient may make the specialist suspect a possible diagnosis of hepatitis B. However, confirmation is carried out by analyzing certain serological markers.
To do this, a blood test will be requested from the patient where the following markers will be measured:
- HBs Ag
- appears in the patient's plasma after 6-8 weeks from infection with the virus.
- HBe Ag
- appears just after HBs Ag and reports the infectivity index. This marker is present in both chronic and acute infections.
- refers to antibodies that fight against viral infection and persist over time if they are IgG-type antibodies. Instead, IgM antibodies disappear over time.
When the specialist is clear about the diagnosis of hepatitis B, he will proceed to indicate the best therapeutic option.
