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: Syphilis - Assay   #160700

Definition: This is a bioassay to measure past or current infection with Treponema pallidum, the bacterium that causes syphilis.

Purpose: The measure determines whether a participant has been infected with Treponema pallidum, the bacterium that causes syphilis. The primary and secondary stages of syphilis are infectious and associated with fetal wastage and the congenital syphilis syndrome. They also increase the risk of human immunodeficiency virus (HIV) acquisition and transmission, while latent disease may be associated with the progression of HIV disease to acquired immune deficiency syndrome (AIDS) and more prominent neurologic disease in HIV-infected persons. The tertiary stage is associated with a vasculitis that may cause neurologic and cardiovascular manifestations and other chronic problems (National Health and Nutrition Examination Survey [NHANES] 2003–2004 Data Documentation).
