What is the purpose of this test?

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?

You should consider ordering the Insulin-like Growth Factor (IGF-1) Blood Test if you have symptoms or concerns related to growth hormone levels. Symptoms to consider:

Unexplained changes in height or growth in children
Noticeable changes in weight or body composition in adults
Symptoms of low energy, fatigue, or decreased strength
Signs of acromegaly, such as enlarged hands or feet, facial changes, or joint pain
Other hormonal imbalances that could affect overall health

If you experience any of these issues, this test can help provide important information to guide your healthcare provider in diagnosing and treating potential growth hormone-related conditions.
