The IGF-1 (Insulin-like Growth Factor-1) test is a blood test that measures the amount of IGF-1 in the blood. IGF-1 is a hormone that, along with growth hormone (GH), helps promote normal bone and tissue growth and development.

The IGF-1 test is often used to support a diagnosis of growth hormone deficiency or growth hormone excess. Because IGF-1 levels are more stable throughout the day compared to growth hormone levels, they provide a useful indication of average growth hormone activity.

An IGF-1 test may be recommended for individuals with signs and symptoms of abnormal growth hormone production. This can include children who are growing slowly and have delayed development or adults who have symptoms of acromegaly (abnormal growth caused by too much growth hormone), such as enlarged hands and feet, facial changes, or joint pain.

No fasting required. Stop biotin consumption at least 72 hours prior to the collection.
