What does quantitative HBsAg mean?
The HBsAg quantitative assay records the amount of hepatitis B surface antigen in a patient’s blood. This, in combination with hepatitis B virus DNA (HBV DNA) testing, enables physicians to monitor and evaluate a patient’s response to peginterferon alfa-2a therapy, and to stop treatment after 24 weeks if indicated.
What is HBsAg qualitative test?
The ARCHITECT HBsAg Qualitative assay is a chemiluminescent microparticle immunoassay (CMIA) for the qualitative detection of hepatitis B surface antigen (HBsAg) in human serum and plasma. SUMMARY AND EXPLANATION OF TEST. The causative agent of serum hepatitis is hepatitis B virus (HBV) which is an enveloped DNA virus.
What is HBsAg value?
For example, a hepatitis B surface antigen (HBsAg) level of less than 1 s/c is considered negative, while a level of more than 5 s/c is considered positive. Any value between 1 and 5 s/c is indeterminate and should be repeated.
What is HBV Quantitative real time PCR?
The HBV Quantitative (Viral load) – Real time PCR test helps to assess the progression of the Hepatitis B virus disease. It also helps to monitor the efficacy of treatment undergoing for the Hepatitis B virus. This test uses Real Time PCR method.
How can I reduce my HBsAg?
A significant reduction of HBV DNA level was observed in those drinking three or more cups of coffee per day, with a median reduction of 523 IU/mL (P = 0.003). Reduction of HBsAg level was observed in those drinking two cups per day, with a median reduction of 37 IU/mL (P < 0.001).
What if I stop taking tenofovir?
Do not stop taking tenofovir without talking to your doctor. If you stop taking tenofovir even for a short time, or skip doses, the virus may become resistant to medications and may be harder to treat.
When can I stop taking tenofovir?
“Stopping [tenofovir] in HBeAg-negative patients with undetectable HBV DNA for at least 3.5 years appears to be safe,” the researchers concluded, noting that tenofovir can be restarted if necessary.
