What is HBsAg quantitative?

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 HBV quantitative test?

A quantitative result expressed in IU/mL and log IU/mL indicates the degree of active HBV viral replication in the patient. Monitoring HBV DNA levels over time is important for assessing disease progression or monitoring a patient’s response to anti-HBV therapy.

How is HBsAg test done?

Taking a hepatitis B test requires a blood sample, which can be collected by a health care professional. For laboratory-based testing, blood is drawn from a patient’s vein. After blood is collected, the sample is sent to a laboratory for analysis.

What is Elisa test for hepatitis?

ORTHO HBc ELISA Test System is a qualitative enzyme-linked immunosorbent assay for the detection of total antibody to hepatitis B virus core antigen (anti-HBc) in human serum or plasma indicated for the screening of blood and blood products intended for transfusion and as an aid in the diagnosis of ongoing or previous …

What is HBsAg Elisa test?

This test is intended for the qualitative detection of hepatitis B surface antigen (HBsAg) at a sensitivity level of 0.10 IU/mL in human serum or plasma. It is intended to be used by professionals as an aid in the diagnosis of an infection with HBV.

What is HBsAg qualitative test?

HBsAg (Hepatitis B surface antigen) – A “positive” or “reactive” HBsAg test result means that the person is infected with hepatitis B. This test can detect the actual presence of the hepatitis B virus (called the “surface antigen”) in your blood.

What is the normal range of HBV DNA quantitative?

The HBV quantitative real-time PCR assay has a quantitative range of 10 to 1,000,000,000 IU/mL.

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.

What is HBsAg ELISA?

What is HBsAg ELISA reactive?

When Elisa test is accurate?

What does HBsAg positive mean?

HBsAg (hepatitis B surface antigen): when this is “positive” or “reactive,” it means the person is currently infected with hepatitis B and is able to pass the infection on to others.
