HBVVL
HEPATITIS B VIRUS (HBV) DETECTION AND QUANTIFICATION BY PCR, SERUM

Test Code HBVVL 
Test HEPATITIS B VIRUS (HBV) DETECTION AND QUANTIFICATION BY PCR, SERUM 
Methodology COBAS® AmpliPrep/COBAS® TaqMan® HBV test, v2.0 
Description This test is useful for quantitation of HBV DNA in the serum of patients with chronic HBV infection, and for monitoring progression of chronic HBV infection and/or response to anti-HBV therapy.

NOTE: This assay should not be used for initial evaluation of patients with HBV infection. Laboratory evaluation of HBV status should begin with HBV serological marker tests. 

Specimen Draw blood in a lavender-top (EDTA) tube, plain red-top, or serum gel tube (SST). Spin down, remove plasma or serum from cells within 24 hours, and send 2.0 mL of serum or EDTA plasma FROZEN in a screw-capped plastic vial. 
Reference Values Undetected
The quantification range of this test is 20 to 170,000,000 IU/mL

Positive results with the comment, “HBV DNA detected, but less than 20 IU/mL", indicate that HBV DNA is present but at a level below the quantifiable range of this assay. When clinically indicated, follow-up testing by this assay is recommended in 1 to 3 months.

Positive results with the comment, “HBV DNA detected, but greater than 170,000,000 IU/mL", indicates that the level of HBV DNA present is above the quantifiable upper limit of this assay. 

Analytic Time 1 Day; Maximum Laboratory Time - 8 Days 
Day(s) Test Set Up Monday 
CPT Code(s) 87517  Hepatitis B Virus, Quant
