LOINC Code 62804-0: Deprecated PhenX measure - fasting serum insulin

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 - fasting serum insulin. 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 - fasting serum insulin
• PhenX measure - fasting serum insulin
• A bioassay to measure serum concentration of insulin, a hormone produced by pancreatic beta cells that regulates the body's ability to metabolize glucose. Concentrations of serum insulin may help distinguish between type 1 and type 2 diabetes. Type 1, or insulin-dependent, diabetes is characterized by autoimmune destruction of the pancreas and eventually leads to absolute insulin deficiency and very low or no circulating insulin. Type 2, or non insulin-dependent, diabetes is characterized by insulin resistance and subjects initially have much higher circulating insulin concentrations. This may be followed by decreasing insulin levels due to pancreatic beta cell exhaustion (American Diabetes Association, 2010). Further, fasting serum insulin alone or combined with fasting plasma glucose can be used as a surrogate estimate of insulin resistance and beta-cell function.
