Quick Facts
- Sample: Blood
- Fasting: No special preparation is required
- Turnaround: 3 - 4 days (may take lo-nger based on weather, holiday, or lab delays)
What This Test Measures
This test directly measures the concentration of Insulin-Like Growth Factor-Binding Protein 3 (IGFBP-3) in the blood. IGFBP-3 is a protein that binds to Insulin-Like Growth Factor (IGF), a hormone involved in regulating cell growth and division. The result is reported as a quantitative measurement of IGFBP-3 levels.
This test measures IGFBP-3 specifically, not IGF itself or any other growth-related hormone. Your healthcare provider may use this measurement, often alongside other testing, to help evaluate growth hormone activity and related conditions. This test alone does not provide a complete evaluation of growth hormone status.
Benefits
- Measures IGFBP-3 levels using a simple blood sample
- May help evaluate growth hormone related conditions
- Can support monitoring of certain cancer treatment responses
- May help assess factors linked to metabolic disorder risk
- Requires no special preparation before testing
- Provides results in as little as 3 to 4 days
Who Is This Test For?
- Individuals with suspected growth hormone deficiency
- People with suspected acromegaly or gigantism
- Individuals with suspected insulin resistance or type 2 diabetes concerns
- Those with suspected osteoporosis or bone growth disorders
- Individuals with liver disease or chronic kidney disease
- People undergoing or with a history of cancer treatment

FAQ
1. What is the purpose of this test?
This test measures the level of IGFBP-3, a protein that binds to Insulin-Like Growth Factor (IGF), in the blood. Your healthcare provider may use this measurement to help evaluate conditions related to growth hormone activity, certain cancers, or metabolic disorders. This test does not diagnose any condition on its own and is typically considered alongside other clinical information.
2. Who would benefit from this test?
This test may benefit individuals with suspected growth hormone deficiency, suspected acromegaly or gigantism, or suspected insulin resistance. It may also benefit those with suspected osteoporosis or bone growth disorders, liver disease, chronic kidney disease, or a history of cancer treatment. A healthcare provider can help determine if this test is appropriate for your situation.
3. When should I order this test?
You may consider this test if a healthcare provider is evaluating growth hormone related concerns, monitoring certain cancer treatments, or assessing factors associated with metabolic disorder risk. This test may also be used as part of ongoing monitoring for previously identified conditions. A healthcare provider can help determine whether this test fits your specific situation.
4. What does this test measure?
This test measures the concentration of IGFBP-3 protein in a blood sample, producing a quantitative, directly measured result. It does not measure IGF itself or other growth related hormones. The result reflects IGFBP-3 levels only and should be interpreted alongside other relevant clinical and laboratory information.
5. Do I need to fast before this test?
No special preparation is required for this test. You do not need to fast or make any dietary changes before your blood sample is collected.
6. How quickly will I get results?
Results are typically available in 3 to 4 days. Turnaround time may take longer based on weather, holidays, or other lab delays.
7. How do I interpret the results?
Interpreting IGFBP-3 results depends on your individual health history, symptoms, medications, and other laboratory findings. Your healthcare provider will consider these factors together, since a single measurement does not fully capture growth hormone activity or related conditions. An abnormal result does not automatically confirm a condition, and a normal result does not rule one out. Always discuss your results with a qualified healthcare provider for proper interpretation.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
8. What should I do if my results are abnormal?
If your IGFBP-3 results are outside the expected range, review them with a qualified healthcare provider. They can help determine what the result means in the context of your overall health and whether any additional evaluation or testing may be appropriate. Do not attempt to interpret or act on results without professional guidance.
9. How often should I get tested?
Testing frequency should be determined by your healthcare provider based on your individual health needs and the reason for testing. There is no universal schedule for repeat testing, so follow your provider's recommendations for monitoring or follow up testing as directed.
