LOINC Code 62807-3: PhenX - serum creatinine assay for kidney function protocol 141401

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component PhenX - serum creatinine assay for kidney function protocol 141401. It is commonly used with the system or sample type ^Patient.

When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Panel type: Panel
• Method: PhenX

What it does not mean

• The code identifies the observation or test, not the actual result.

Key facts

• PhenX - serum creatinine assay for kidney function protocol 141401
• This protocol provides instructions for drawing, processing and storing blood for the serum creatinine assay according to the National Health and Nutrition Examination Survey (NHANES) methods. Creatinine concentration in a participant's serum is measured according to the Jaffe rate method. The Diabetes Working Group notes that the Serum Creatinine assay can be done in conjunction with Cystatin C assay (see Diabetes Supplemental Information Cystatin C) to yield more information about kidney disease. In particular, comparing and contrasting the polymorphisms associated with each assay can identify "true" markers for kidney function (see Kottgen et al., 2009 for more information).
