Insulin-like Growth Factor 1 (IGF-1)
What is Insulin-like Growth Factor 1 (IGF-1) and why is it important?
The IDS-iSYS Insulin-like Growth Factor-I (IGF-I) assay is an in
vitro diagnostic device intended for the quantitative
determination of IGF-I in human serum or plasma on the IDS system.
Results are to be used in conjunction with other clinical and
laboratory data to assist the clinician in the assessment of
growth disorders.
When to consider Insulin-like Growth Factor 1 (IGF-1)?
- If a child exhibits stunted growth, short stature, or delayed puberty.
- If an adult shows signs of growth hormone deficiency, such as decreased muscle mass, increased body fat, reduced bone density, or chronic fatigue.
- If symptoms suggest growth hormone excess, including enlarged hands and feet, changes in facial features, joint pain, excessive sweating, or headaches.
- When a healthcare provider suspects a pituitary gland disorder, as IGF-1 levels often reflect growth hormone production.
Who benefits from Insulin-like Growth Factor 1 (IGF-1)?
- Individuals with suspected growth hormone deficiency, characterized by slow growth in children or specific symptoms in adults.
- Those being evaluated for potential growth hormone excess (acromegaly or gigantism), which can lead to abnormal tissue growth.
- Patients undergoing treatment for growth disorders, to monitor the effectiveness of therapy.
- Anyone experiencing symptoms that may indicate an imbalance in growth hormone levels, as recommended by their healthcare provider.
When is the Insulin-like Growth Factor 1 (IGF-1) used?
The IGF-1 test is commonly used to aid in the diagnosis and monitoring of various conditions related to growth hormone imbalance. These include:
- Growth Hormone Deficiency (GHD) in children, leading to short stature and delayed development.
- Adult Growth Hormone Deficiency (AGHD), which can manifest as reduced muscle mass, increased body fat, fatigue, and decreased bone density.
- Acromegaly, a condition in adults caused by excessive growth hormone production, leading to enlargement of hands, feet, and facial features.
- Gigantism in children, a rare condition resulting from excess growth hormone before puberty, leading to abnormal height.
- Evaluation of pituitary gland disorders, as the pituitary gland produces growth hormone that regulates IGF-1.
- Monitoring the effectiveness of growth hormone therapy or treatment for growth hormone-related tumors.
- Investigating symptoms such as unexplained weight gain or loss, persistent fatigue, changes in body composition, or abnormal growth patterns.
Important Considerations
It is important to discuss your IGF-1 test results with a qualified healthcare provider. They can interpret the results in the context of your overall health, symptoms, and medical history, and recommend appropriate next steps. This test is a tool to aid diagnosis and management of growth disorders, not a standalone diagnostic. Consultation with a medical professional is essential before making any health decisions.
