Test Name

Test ID: FHBG    
Hepatitis B Virus Genotyping

Specimen Type Describes the specimen type needed for testing

Plasma EDTA

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Draw blood in lavender (EDTA) tube(s). Spin down and send 2 mL plasma frozen in a plastic vial.


Required: 1. Viral Load

               2. Viral Load Date


Note: Red-top serum and serum gel tube(s) are acceptable.


Note: This test may be unsuccessful if the HBV Viral load is less than log 3.0 or 1,000 IU/mL of plasma.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

0.5 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
