Review Measure

Essential Measures are only those items that are critical to the collection of the Measure or are necessary for the interpretation of results. Essential Measures are integral to the Measure. Without such information the data collected would be incomplete and/or misleading.
An additional PhenX Measure that the user may find helpful based on the selection of a particular PhenX Measure. Related PhenX Measures can include additional Measures that are needed to calculate a Derived Variable (e.g., Weight and Height are needed to calculate BMI), Measures that are commonly used in presentations and publications to present the value of the chosen Measures (e.g., Height and Weight by Race and Ethnicity), Measures that are conceptually related to the chosen Measure (e.g., Current Educational Attainment is conceptually related to Annual Family Income and Arm Span is conceptually related to Height), Measures that are physiologically and/or biologically related to the chosen Measure (e.g., Stroke and Heart Disease). Related PhenX Measures are suggestions only.
The Collections are an alternative to the research domains for browsing the PhenX Measures. Measures that are related by a specific topic are grouped together.

Measure: Hepatitis B - Assay   #160400

Definition: This is a bioassay to measure hepatitis B (HBV).

Purpose: 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.
