ARCHITECT® HBsAg Reagent Kit

These reagents are used with the Abbott ARCHITECT® Instrument System to identify certain virus proteins associated with hepatitis B virus (HBV)2. If these virus proteins are present, then the patient is likely to be infected with HBV.

How does it work?

• A sample of the patient's blood is placed into reaction wells containing microparticles coated with antibodies to HBV.
• If the blood sample contains HBV proteins, they will bind to the microparticles in the reaction wells.
• This reaction is detected by another substance that produces light, which is then measured to determine the presence of HBV in the blood.
• If this first test is positive, the patient's blood is retested to confirm the presence of HBV.

When is it used?

This test is used to confirm whether or not a person is infected with HBV.

What will it accomplish?

It can be used for testing pediatrics and pregnant women to see if the child may be at high risk for HBV infection.

When should it not be used?

This test should not be used for screening blood donors because FDA has not licensed it for this purpose.
