Key facts

  • PhenX measure - assay for hepatitis B
  • This is a bioassay to measure hepatitis B (HBV). The measure determines whether a participant is infected with the hepatitis B virus (HBV). HBV constitutes a major public health problem because of the morbidity and mortality associated with the acute and chronic consequences of this infection. HBV can be spread by blood, bodily fluids, and at childbirth from the mother to the child. HBV infects the liver and can cause scarring (cirrhosis), liver failure, and liver cancer. Because of the high rate of asymptomatic infection, HBV often goes undetected.
