LOINC Code 62853-7: Deprecated PhenX measure - glycosylated hemoglobin assay that reflects long-term glucose concentration

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 - glycosylated hemoglobin assay that reflects long-term glucose concentration. 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 - glycosylated hemoglobin assay that reflects long-term glucose concentration
• PhenX measure - glycosylated hemoglobin assay that reflects long-term glucose concentration
• A bioassay to measure percent glycosylated hemoglobin (Glycohemoglobin, Hemoglobin A1C, A1C), or the amount of glucose attached to the hemoglobin in red blood cells (American Diabetes Association, 2009). Glycosylated hemoglobin is a well recognized assay of blood glucose concentration over the preceding several months and results are predictive of diabetes complications and outcomes. The glycosylated hemoglobin assay can also be used to determine if a person has diabetes (American Diabetes Association, 2010).
