What is HBV DNA PCR test?
What is HBV DNA PCR test?
The HBV DNA test is performed on a blood sample using a Polymerase Chain Reaction (PCR) technique that rapidly generates HBV DNA fragments so they can be measured. Today, viral load is usually measured using international units per milliliter (IU/mL).
What is the normal range of HBV?
Any value between 1 and 5 s/c is indeterminate and should be repeated. For hepatitis B surface antibody (anti-HBs), a level less than 5 mIU is considered negative, while a level more than 12 mIU is considered protective. Any value between 5 and 12 mIU is indeterminate and should be repeated.
What is the cost of HBV DNA test?
Price: Rs. 2500 Rs. This test is intended for use as an aid in management of HBV infected patients and is not intended for use in the initial diagnosis or confirmation of HBV infection.
What is HBV DNA viral log?
The hepatitis B virus DNA quantification, also known as the viral load test, is a blood test that measures the amount of hepatitis B virus DNA (viral load) in the blood of chronically infected patients. The blood is tested using a Polymerase Chain Reaction (PCR) technique.
What does HBV DNA negative mean?
Negative HBV DNA does not mean a controlled hepatitis B. Hepatitis B patients transferred to HBV DNA positivity during the anti-viral therapy are easily to show disease progression, and then special attention should be paid to the HBV DNA monitoring.
What is HBV real time PCR Quant?
Hepatitis B Virus DNA, Quantitative, Real-Time PCR – Chronic carriers will persist in producing detectable HBV. Patients with chronic liver disease of unknown origin most commonly have HBV that is detected by viral DNA testing. Quantitative measurement of HBV viral DNA may be used to monitor progression of disease.
What is normal range of HBV PCR quantitative?
The quantitative test has a range of 10 IU/mL to 1,000,000,000 IU/mL.
What is PCR test for?
What is a PCR test? PCR means polymerase chain reaction. It’s a test to detect genetic material from a specific organism, such as a virus. The test detects the presence of a virus if you have the virus at the time of the test.
What does HBV DNA not detected means?
An “Undetected” result indicates that hepatitis B virus (HBV) DNA was not detected in the serum specimen. A result of “<10 IU/mL (<1.00 log IU/mL)” indicates that HBV DNA is detected, but the HBV DNA level present cannot be quantified accurately below this lower limit of quantification of this assay.
What is HBV quantitative test?
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.
