What is it? Abbott RealTime HBV is a laboratory test kit that measures the amount of hepatitis B viral DNA in the blood of an individual infected by the hepatitis B virus (HBV). Viral DNA is the genetic material from the hepatitis B virus. The individual's hepatitis B viral DNA is measured before beginning treatment and during treatment to assess an individual's response to the treatment. This test is used with the Abbott m2000sp and m2000rt automated instruments and the results from the Abbott RealTime HBV test must be used in combination with other relevant clinical and laboratory findings.

How does it work? A sample of a patient's blood is obtained and sent to a clinical laboratory. DNA is separated from the cells in the blood sample and mixed with test chemicals using the automated Abbott m2000sp system. The resulting mixture is put into the m2000rt analyzer. The m2000rt analyzer calculates the amount of HBV DNA in the patient's blood based on the amount of produced light measured by the analyzer after completion of the reaction. Measurement of the amount of HBV DNA in the blood together with clinical information and other laboratory blood tests used by physicians help determine a patient’s response to treatment.

When is it used? This is a laboratory test used for adult individuals infected with the hepatitis B virus, to evaluate the treatment, together with other laboratory and clinical information.

What will it accomplish? Test results help determine an individual’s response to treatment and aid in the management of patients with HBV infection undergoing anti-viral therapy.

When should it not be used? This lab test should not be used if it is not ordered by a physician. The assay should not be used to determine if a person is infected with the hepatitis B virus or to determine the stage of HBV infection. It should not be used to screen blood or blood products for transfusion. And, it should not be used to predict the outcome of anti-viral treatment.
