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: Current Pregnancy Status   #240600


This measure is used to determine if a woman is currently pregnant or not.


A biological assay is the most accurate pregnancy test. It may be important to know whether or not a woman is pregnant prior to some tests (e.g., dual-energy X-ray absorptiometry) or to the use of pharmaceutical agents as in a clinical trial. In addition, pregnancy may influence the results of several physical and health measures such as weight, blood pressure, stress, and depression. This measure can also be used to make a determination of whether the subject can be included or excluded from a research study or whether she should be excluded.
