PLASMA, HEPATITIS B VIRUS DNA, QUANTITATIVE RT PCR

Ambulatory Transport Temperature to Inova Central Lab: Refrigerated Specimen Stability: 24 hours

LAB17456 HBVQT

HBVQT

Testing is performed with the Roche cobas HBV assay on plasma. These results should not be compared to results generated from other test systems or other specimen types. If Quest testing is necessary in order to track viral loads from previously positive patients please request testing with the EPIC Miscellaneous order. This test is intended for use as an aid in the management of patients with chronic HBV infection undergoing anti-viral therapy. The test can be used to measure HBV DNA levels at baseline and during treatment to aid in assessing response to treatment. The cobas HBV test is not intended for use as a diagnostic test to confirm the presence of HBV infection.

Processing Instructions: Specimen must be centrifuged within 24 hours and plasma aliquoted to a secondary container immediately after centrifugation. Collecting sites should centrifuge and aliquot immediately if specimen cannot be delivered to the lab within 24 hours Preferred Testing Volume: 1.5 mL plasmaMinimum Testing Volume: 1.5 mL plasma Transport Temperature: Refrigerated Stability: UnspunAmbient: 24 hoursRefrigerated : 24 hoursFrozen: NASeparated PlasmaAmbient: NARefrigerated : 6 daysFrozen: 12 weeks Causes for Rejection: Unlabeled, mislabeled, wrong tube type, exceeds specimen stability, QNS or presence of clot in separated plasma
