LOINC Code 79202-8: Somatotropin 45 Min post dose arginine+insulin [Mass/Vol]

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 Somatotropin^45M post dose arginine+insulin. It is commonly used with the system or sample type Ser/Plas.

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
• Order vs observation: Both

What it does not mean

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

Key facts

• Somatotropin [Mass/volume] in Serum or Plasma --45 minutes post dose arginine+insulin
• Somatotropin^45M post dose arginine+insulin
• This test is part of one growth hormone deficiency testing procedure, in which glucose and growth hormone levels are measured at specific time intervals after the administration of arginine and insulin. Normally, arginine and insulin-induced hypoglycemia stimulate the release of growth hormone, so patients without growth hormone deficiency will have a significant increase in serum growth hormone in response to arginine and insulin administration. In patients with growth hormone deficiency, however, the increase in and the absolute peak of the growth hormone level will be much lower than expected.
