Insulin-like Growth Factor 1 Blood Test

Sample Report
Specimen Type: Blood


Insulin-like Growth Factor 1 Blood Test

This test measures the level of Insulin-Like Growth Factor 1 (IGF-1) in the blood.  IGF-1 is a hormone produced by the liver, muscle and other tissues in response to Growth Hormone (GH) production by the pituitary gland and is vital for normal tissue and bone growth and development.  IGF-1 typically mirrors GH levels.  Because IGF-1 levels are more stable than GH levels, measuring IGF-1 can be useful for determining average GH levels.  Measuring IGF-1 can be useful for evaluating deficiency or excess of Growth Hormone as well as evaluating pituitary function.

IGF-1 is typically ordered along with a Growth Hormone test when someone has symptoms of Growth Hormone deficiency or an underactive pituitary gland.  It may also be ordered to monitor treatment for pituitary tumors.

Turnaround time for the IGF-1 test is typically 1-3 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.


IGF-1 testing does not have any special requirements.
