What this test is
The IGF-1 Insulin Blood Test is a blood test that measures the level of insulin-like growth factor 1 (IGF-1). IGF-1 is produced mainly by the liver in response to growth hormone and is a more stable indicator of growth hormone activity than growth hormone itself. It is commonly used to evaluate growth hormone-related conditions.
What it measures
- IGF-1 — reflects average growth hormone activity over time
What the test involves
The test involves a standard blood draw from a vein in your arm. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test to help evaluate growth hormone excess or deficiency, or to monitor certain treatments. It is also used when symptoms suggest a growth hormone-related disorder.
Preparation
Preparation instructions can vary, so follow the specific instructions provided by the collection lab. This may include fasting or avoiding certain medications before the test.
How results are reported
Results are typically reported as a numeric value with a reference range. Reference ranges vary by laboratory, so your result should be interpreted in the context of the lab that performed the test.
