HEPATITIS B VIRUS DNA, QUANTITATIVE PCR |
||
ORDERING INFORMATION: |
Geisinger Epic Procedure Code: LAB2426 Geisinger Epic ID: 17684 | |
SPECIMEN COLLECTION |
||
Specimen type: |
Plasma | |
Preferred collection container: |
||
Specimen required: |
Must collect one 6 mL pink top EDTA tube or three 3 mL lavender top EDTA tubes. Minimum of 1.5 mL of plasma required for testing. | |
| SPECIMEN PROCESSING |
||
Specimen processing instructions: |
Send unspun collection tube to testing lab. Plasma will be separated at testing lab. Separate plasma within one day of collection and transfer plasma to a screw-capped, plastic aliquot tube. Freeze immediately at -20°C. | |
Transport temperature: |
Refrigerated (2-8°C). | |
Specimen stability: |
Whole Blood: Refrigerated (2-8°C) up to 72 hours. Room temperature (15-30°C) up to 24 hours. Plasma: Refrigerated (2-8°C) up to 72 hours. Room temperature (15-30°C) up to 20 hours. Frozen (-20°C) up to 60 days. Can be subjected to at most 3 freeze thaw cycles. Thawed samples may be stored at 2-8°C for up to 6 hours prior to testing. Frozen (-70°C) Long term. Can be subjected to at most 3 freeze thaw cycles. Thawed samples may be stored at 2-8°C for up to 6 hours prior to testing. |
|
Rejection criteria: |
Specimens stored or transported at incorrect temperature, stability limits exceeded, improper collection tube used, insufficient volume, improperly labeled/identified specimens. | |

Test includes: |
Quantitation of hepatitis B viral DNA by PCR. | |
Methodology: |
Real-time Polymerase Chain Reaction (PCR) |
|
Synonyms: |
Hepatitis B Viral Load, HBVL, Viral Load, Hepatitis B, Hep B, Hep B Viral Load, Quant Viral Load
|
|
Clinical significance: |
This test is utilized for the detection and quantitation of hepatitis B virus (HBV) DNA in the plasma of patients with HBV infection (i.e. hepatitis B surface antigen positive), monitoring disease progression in chronic HBV infection, and monitoring response to anti-HBV therapy. | |
