Description
The Insulin-like Growth Factor (IGF-1) Blood Test measures the levels of IGF-1, a hormone that plays a crucial role in growth and development. IGF-1 is produced in the liver and is stimulated by growth hormone (GH) from the pituitary gland. This test helps assess growth hormone function and can provide insights into various conditions, such as growth disorders in children and hormonal imbalances in adults.
By measuring IGF-1 levels, healthcare providers can evaluate if a person has excess or insufficient growth hormone activity. Elevated levels of IGF-1 may indicate conditions like acromegaly or gigantism, while low levels could suggest growth hormone deficiency or other underlying health issues. This test is a valuable tool for diagnosing and monitoring these conditions, helping guide treatment decisions.
Who should get this test?
- Children with growth concerns, such as being significantly shorter or taller than peers
- Adults experiencing unexplained changes in weight or body composition
- Individuals with symptoms of growth hormone deficiency, such as fatigue or reduced muscle mass
- Patients diagnosed with acromegaly or gigantism who need monitoring
- People with conditions that may affect hormone levels, such as pituitary disorders
When should I order the Insulin-like Growth Factor (IGF-1) Blood Test?
