The IGF-1 Test measures insulin-like growth factor 1, a hormone regulated by growth hormone (GH), to assess growth and endocrine function. Abnormal levels may indicate growth disorders, acromegaly, gigantism, or GH deficiency. Doctors order this test to evaluate delayed growth, short stature, excessive growth, or pituitary disease and to monitor GH therapy. Results provide valuable insight into hormone balance, metabolism, and overall endocrine health.

The IGF Binding Protein 3 (IGFBP-3) Test measures IGFBP-3, the primary carrier of insulin-like growth factor 1 (IGF-1), to evaluate growth hormone activity. Abnormal levels may indicate growth disorders, pituitary dysfunction, or nutritional problems. Doctors use this test with IGF-1 to assess short stature, delayed or rapid growth, and monitor therapy for growth hormone deficiency or excess, supporting accurate diagnosis and treatment.

The IGF Binding Protein 1 (IGFBP-1) Test measures IGFBP-1, a protein that regulates insulin-like growth factor (IGF) activity and reflects insulin sensitivity. Abnormal levels may indicate insulin resistance, type 2 diabetes risk, or metabolic syndrome. Doctors use this test to evaluate glucose regulation, investigate metabolic disorders, and support early detection of endocrine imbalances that affect growth, energy balance, and long-term health.
