Specimen Collection Manual and Test Catalog

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.

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. Test is not available for add-on

Refrigerated (2-8°C).

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.

Specimens stored or transported at incorrect temperature, stability limits exceeded, improper collection tube used, insufficient volume, improperly labeled/identified specimens.

HBV DNA not detected.

Quantitation of hepatitis B viral DNA by PCR.

Hepatitis B Viral Load, HBVL, Viral Load, Hepatitis B, Hep B, Hep B Viral Load, Quant Viral Load

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. This is a quantitative molecular assay with a linear range of 10 IU/mL (1.0 Log IU/mL) to 1,000,000,000 IU/mL (9.0 Log IU/mL).
