Batched; 3 days per week


Report Available
Results available 2-7 days after receipt


Reference Range
Not Detected

A qualitative interpretation of either DETECTED or NOT DETECTED is provided.  When HBV is detected, a quantitative result of IU/mL and log(IU/mL) is also provided.  The limit of quantitation for this assay is 10-1,000,000,000 IU/mL or 1.00-9.00 log(IU/mL).

Positive results are reported to the Illinois Board of Health. 


Clinical Significance
Intended for use as an aid in the management of patients with chronic HBV infection undergoing anti-viral therapy. The assay can be used to measure HBV DNA levels at baseline and during treatment to aid in assessing response to treatment.

This assay is not intended to be used in screening blood, blood products, or cell, tissue, and cellular and tissue-based products (HCT/Ps), or as a diagnostic test to confirm the presence of HBV infection.


Performing Laboratory
Alverno Central Lab
