Insulin-like Growth Factor 1 (IGF-1) is a hormone produced by the liver in response to growth hormone. It plays a crucial role in growth, development, and metabolism. IGF-1 levels can fluctuate throughout life, influenced by factors like age, sex, and overall health.

Who is it for?

This test is often recommended for individuals who are experiencing:

• Growth concerns: Children or adolescents who appear to be growing slower than expected.
• Hormone imbalances: Adults with symptoms such as fatigue, weight gain, or decreased muscle mass.
• Metabolic disorders: Individuals with conditions like diabetes or hypothyroidism.
• Infertility: Women with difficulty conceiving.

Outcome of the test:

The results of an IGF-1 test can help to:

• Assess growth hormone function: Low IGF-1 levels may indicate a deficiency in growth hormone.
• Diagnose metabolic disorders: Abnormal IGF-1 levels can be associated with conditions like hypothyroidism or diabetes.
• Monitor treatment effectiveness: For individuals undergoing treatment for growth hormone deficiency or other conditions, IGF-1 levels can be used to assess the effectiveness of therapy.

Preparation before taking the test:

• Fasting: You will typically be asked to fast for a certain period before the test, usually 8-12 hours.
• Medication review: Inform your healthcare provider about any medications or supplements you are currently taking, as they can potentially affect IGF-1 levels.

It’s important to consult with a healthcare professional to determine if an IGF-1 test is appropriate for you and to discuss the specific implications of the results.
