Additional Information
For BJH Laboratory Use Only
Alternate Tube types are acceptable for Hepatitis serology testing only. Alternate tube types will not Reflex to Hep C RNA:
Note: Performance has not been established with cord blood, neonatal specimen, cadaver specimen, heat-inactivated specimen, or body fluid other than serum or plasma such as saliva, urine, amniotic fluid, or pleural fluid.
Analyte Stability:
Ambient temperature stability: Test immediately or refrigerate
Separated from cells refrigerated stability at 2° C to 8° C: 7 days
Frozen at </= -20° C stability: 980 days. Avoid more than 5 freeze/thaw cycles. Repeated freeze/thaw cycles can cause analyte deterioration.
Laboratory Processing Instructions:
Test performed in BJH Core lab. Processed by Cobas 8100 automated line for delivery to the Roche Cobas e801. Completed specimens are stored refrigerated for 5 days.
Upon confirmation, all positive HCV and HBsAg results must be reported to the state within 3 days.
