IGF & IGF-BP3 Hormone Assessment | Pathology


IGF1 and IGF-BP3 levels can influence a range of bodily functions and cellular repair processes. IGF-BP3 is the main carrier of IGF1, and levels can also signify the body’s production of human growth hormone (HGH). This assessment requires a simple SST serum test, and can highlight any imbalances or anomalies in the body’s IGF1 and IGF-BP3 levels.




This assessment will measure the levels of insulin-like growth factor (IGF1) in the body. This test will also consider levels of IGF-BP3, which is an insulin-like growth factor that binds three proteins. 

IGF1 is naturally produced in the body and plays an important role in cell repair in the muscles, brain and heart. It contains seventy amino acid polypeptides that are produced by the liver and endocrine system. 

This hormone has a similar structure to insulin, and holds many important anabolic roles in the body from childhood through to adulthood. It has growth-promoting effects on almost every cell in the body, including skeletal muscle, cartilage, bone, liver, nerves and lungs. In addition to these insulin-like properties, IGF1 can also regulate cell growth and development to support DNA synthesis. 

IGF-BP3 is the main carrier of IGF1 and accounts for 80 per cent of all IGF binding, making it the body’s most abundant protein. Testing for this molecule can indicate whether the body is producing a normal amount of human growth hormone (HGH).

Step 1: Receive Pathology Forms

You will receive a package which will include all instructions, pathology form, details of sample collection locations.

Step 2: Pathology assessment

Once your samples are received by the lab they will be assessed. The turnaround time for results is 7 – 10 business days but please be aware laboratory times may vary and you may experience a delay in results.

Step 3: Medical Team review results

Once your confidential results have been sent to the medical team for review, they will call you to discuss your results and appropriate treatment options moving forward.

Step 4: Results sent to the patient

Finally, a copy of your results will be sent through to you for your reference.
