Interpretive Data
The quantitative range of this test is 1.00-9.00 log IU/mL (10-1,000,000,000 IU/mL).
An interpretation of "Not Detected" does not rule out the presence of inhibitors in the patient specimen or HBV DNA concentration below the level of detection of the test. Care should be taken when interpreting any single viral load determination.
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. Results must be interpreted within the context of all relevant clinical and laboratory findings.
This assay should not be used for blood donor screening, associated reentry protocols, or for screening human cell, tissues and cellular tissue-based products (HCT/P).
FDA
Note
The limit of quantification for this DNA assay is 1.00 log IU/mL (10 IU/mL). If the assay DETECTED the presence of the virus but was not able to accurately quantify the viral load, the test result will be reported as "Not Quantified, Detected".
