Test Frequency and Turnaround Time (TAT)
Hepatitis D serology testing is a referred out test and is performed at the National Microbiology Laboratory (NML) in Winnipeg for HBsAg positive specimens.
Turnaround time is up to 14 days from receipt by PHO laboratory.
This test is performed on HBsAg positive samples. If HBsAg status is not indicated on the requisition, HBsAg will be tested at PHOL using a chemiluminescent microparticle immunoassay (CMIA).
Hepatitis D antibody is detected using an Enzyme Immunoassay (EIA) at NML.
