LOINC Code 62808-1: Deprecated PhenX measure - urinary microalbumin assay for kidney function

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 measure - urinary microalbumin assay for kidney function. 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: DEPRECATED
• Method: PhenX

What it does not mean

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

Key facts

• Deprecated PhenX measure - urinary microalbumin assay for kidney function
• PhenX measure - urinary microalbumin assay for kidney function
• A bioassay to measure urine concentration of albumin, which is produced by the liver and is the most abundant protein in the blood. Albumin is only filtered out of blood by the kidneys when there is damage to the glomeruli, as in diabetes. The earliest measure of this damage is the appearance of small (micro-) amounts of albumin in the urine. Additionally, the ratio of urine albumin to urine creatinine, called microalbuminuria, is used to predict the risk of nephropathy (National Health and Nutrition Examination Survey and University of Minnesota Laboratory Procedure Manual for Urinary Creatinine, 2008).
