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: Cystatin C Assay for Kidney Function   #250700

Definition: A bioassay to measure serum concentration of cystatin C, a protein that is filtered out of the blood by the kidneys.

Purpose: Cystatin C is a protein produced by the body. Cystatin C measurements can indicate kidney function problems and assess kidney disease. For the elderly, those who are overweight, and people who have a lot of muscle mass (e.g., body builders), Cystatin C-based estimates for glomerular filtration rate (eGFR) are believed to be less influenced by muscle mass or diet than creatinine-based estimates (National Kidney Foundation, 2015).This measurement of renal function is particularly important to old people with reduced muscle mass, which makes other assays less accurate.
