Hepatitis B Virus (HBV) Quantitative Real-time PCR

Test Code: 1100

Cpt Code:

87517 (x1)

Clinical Utility

Hepatitis B quantitative DNA PCR can be used in conjunction with clinical presentation and other laboratory markers of disease status as an aid in managing individuals infected with HBV. Results from the assay can potentially be used to assess disease progression and to monitor the efficacy of antiviral therapy by measuring changes in HBV DNA levels during the course of therapy. Viral load tests should not be used to diagnose HBV infection.

Procedure

Extraction of DNA from specimen; amplification and detection of hepatitis B genotypes A through H using real-time, quantitative PCR. An internal control is added to ensure the extraction was performed correctly and the PCR reaction was not inhibited. RealTime HBV is a product of Abbott Laboratories. It is FDA approved for in vitro diagnostic use.

Specificity

Detects all 8 HBV genotypes. The primers and probes used in this assay are specific for HBV.

Causes For Rejection

Specimens beyond their acceptable length of time from collection as listed in the specimen handling or specimen types other than those listed.

Turnaround Time

Same day (within 8 to 12 hours of receiving specimen), Monday through Saturday

Shipping

Ship Monday through Friday. Friday shipments must be labeled for Saturday delivery. All specimens must be labeled with patient's name and collection date. A Viracor-IBT test requisition form must accompany each specimen. Multiple tests can be run on one specimen. Ship specimens FedEx Priority Overnight® to: Viracor-IBT Laboratories, 1001 NW Technology Dr, Lee's Summit, MO 64086

Specimen Information

1101 plasma

NY approved. Assay Range: 10 IU/mL to 1.0 x 109 IU/mL, HBV DNA detected below 10 IU/mL will be reported as "<10 IU/mL". Reported in 2 formats: IU/mL and Log10 IU/mL. Collect 4-5 mL whole blood in EDTA, ACD or PPT, centrifuge within 6 hours of draw and transfer 2 mL plasma to a sterile, screw top tube (minimum volume 0.7 mL). If the specimen was collected in PPT, the entire tube can be shipped frozen following centrifugation. If shipped ambient, separated plasma fraction must arrive within 24 hours of draw.

1110 serum

NY approved. Assay Range: 10 IU/mL to 1.0 x 109 IU/mL, HBV DNA detected below 10 IU/mL will be reported as "<10 IU/mL". Reported in 2 formats: IU/mL and Log10 IU/mL. Collect 4-5 mL whole blood in red-top or SST, centrifuge within 6 hours of draw and transfer 2 mL serum to a sterile, screw top tube (minimum volume 0.7 mL). If the specimen was collected in SST, the entire tube can be shipped frozen following centrifugation. If shipped ambient, separated serum fraction must arrive within 24 hours of draw.
