Confirmatory Test for HBsAg

Indications

Specimen Required

​3 mL plain blood for single marker. 6 – 8 mL plain blood for panel of markers.

(a) To diagnose acute hepatitis B infection or the carrier state, send blood for HBsAg QuaLitative and anti-HBc IgM.

(b) To determine immune status following past infection or vaccination, send blood for anti-HBs.

(c) In the case of a carrier, send blood for HBeAg and anti-HBe.

(d) To monitor response to HBV therapy, send blood for HBsAg QuaNtitative.

Storage and Transport

​Refrigerate samples if delay in transporting to laboratory is anticipated. Do not freeze.

Method

​Chemiluminescent Microparticle Immunoassay (for all above)
