Diese Seite informiert über die Bestimmung des Genotyps des Hepatitis-B-Virus (Serum/Plasma) für Patientinnen und Patienten.

Warum dieser Test für Sie von

Hepatitis B virus (HBV) exists in several genetic forms, or genotypes. Knowing your genotype helps doctors choose the most effective treatment and manage your health more precisely. Different genotypes may respond differently to antiviral medications and may affect how quickly the virus progresses.

How the Test Works

This test uses a blood sample (either serum or plasma) to detect the specific genetic sequence of the HBV. Advanced laboratory techniques, such as **immunoassay** or **nucleic acid testing**, analyze the viral DNA to determine which genotype you have. Results are typically reported as a genotype number (e.g., 1, 2, 3, etc.).

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The blood is processed to separate the serum or plasma for testing. This test does not require fasting or special preparation beyond standard blood draw procedures.

What to Expect After Testing

After your blood sample is collected, it is sent to a laboratory for analysis. Results are usually available within 1–2 weeks, depending on the lab’s processing time. Your healthcare provider will discuss the results with you and explain any next steps, such as treatment options or follow-up care.
