Hepatitis B, Surface Antigen. Screening

Clinical information

Diagnostic Utility:

This is the qualitative detection of the Hepatitis B surface antigen (HBsAg) and its determination is useful in:

• Identification of chronic carriers of the Hepatitis B virus.
• Blood component transfusion.
• Transplantation of progenitor cells, solid organs, and tissues.
• Screening for infectious diseases in egg and semen donors.

Method:

Chemiluminescent immunoassay (ChLIA).

Reference Values

Possible results are: Reactive and Non-Reactive.

Diagnostic Algorithm:

In case of a reactive HBsAg result, the confirmatory test for surface antigen by neutralization can be requested.

(*) Only carried out upon request.

Turnaround Time:

Maximum 2 working days
