INSULIN-LIKE GROWTH FACTOR1 (IGF-1) / SOMATOMEDIN C

The IGF‑1 (Somatomedin C) blood test measures the circulating concentration of insulin‑like growth factor 1, a hormone produced mainly by the liver in response to growth hormone (GH). IGF‑1 reflects integrated GH activity over time and is therefore a reliable marker for assessing growth hormone deficiency or excess without the variability seen in single GH measurements. This home blood test provides accurate laboratory quantification with convenient venous sample collection across Dubai and the UAE.

This test is commonly used to investigate short stature or delayed growth in children, evaluate suspected pituitary disorders in adults, and monitor treatment for acromegaly or GH replacement. It can also contribute to fertility assessments where GH‑IGF axis dysfunction is suspected. Results are reported with age‑ and sex‑adjusted reference ranges and should be interpreted by your physician alongside clinical findings and other investigations.

• Insulin‑Like Growth Factor 1 (IGF‑1) — serum concentration
• Somatomedin C — alternate designation reported
• Age‑ and sex‑adjusted reference range

• Investigation of short stature or delayed growth in children
• Suspected growth hormone deficiency in adults
• Diagnosis and monitoring of acromegaly (GH excess)
• Evaluation of unexplained infertility where GH/IGF axis may play a role
• Monitoring response to GH replacement or acromegaly therapy

• Accurate assessment of GH axis using a stable, integrated biomarker
• Convenient at‑home venous sample collection across Dubai and the UAE
• Age‑ and sex‑adjusted reporting to aid clinical interpretation
• Supports diagnosis, treatment planning, and therapy monitoring

• At‑home venous blood sample collected by a licensed phlebotomist
• Morning sample preferred; fasting is usually not required unless advised
• Inform the technician/physician about current medications (GH therapy, estrogens, steroids)
• Provide patient age and sex (and height for pediatric samples) for accurate reference comparison
