What Is an IGF Binding Protein-1 (IGFBP - 1)?
The IGF Binding Protein-1 (IGFBP - 1) test measures the level of IGFBP-1, a protein produced mainly by the liver, in the blood. This protein binds to insulin-like growth factors (IGFs) in the bloodstream, regulating how active these growth factors are in the body. Doctors order this test to investigate growth disorders, metabolic conditions, and insulin-related problems. A small blood sample (serum) collected after an overnight fast is used for this test.
What Does an IGF Binding Protein-1 (IGFBP - 1) Measure?
The IGFBP - 1 test analyses a single key protein in the blood. Here is what it measures and why it matters:
| Parameter | What It Tells Us |
|---|---|
| IGFBP-1 (Serum Level) | Reflects how much of this regulatory protein is circulating in the blood; helps assess IGF activity, insulin regulation, and related metabolic functions |
IGFBP-1 is the only IGF binding protein that shows rapid, large changes in response to meals and insulin levels. Because insulin strongly suppresses IGFBP-1 production, its level in the blood acts as a useful indirect marker of insulin activity and metabolic balance.
Why Is an IGF Binding Protein-1 (IGFBP - 1) Done?
Doctors order the IGFBP - 1 test for a range of reasons, from investigating hormonal symptoms to monitoring specific metabolic conditions.
Common Symptoms That May Require This Test
The following symptoms may prompt a doctor to request this test:
- Unexplained changes in growth patterns
- Signs of insulin resistance, such as difficulty managing blood sugar levels
- Irregular menstrual cycles
- Symptoms of metabolic syndrome (a cluster of conditions including high blood pressure, excess weight, and abnormal blood sugar)
- Suspected growth hormone disorders
- Symptoms related to PCOS (polycystic ovary syndrome)
- Suspected premature rupture of membranes during pregnancy
Conditions This Test Can Help Detect
This test can provide information relevant to a number of conditions, including:
- Growth hormone deficiency
- Acromegaly (a condition where excess growth hormone causes enlarged features)
- Cushing disease (caused by prolonged exposure to high cortisol levels)
- Polycystic ovary syndrome (PCOS)
- Insulin resistance or hyperinsulinaemia (abnormally high insulin levels)
- Type 1 and Type 2 diabetes
- Liver disease
- Pre-eclampsia risk during pregnancy (a condition involving high blood pressure in pregnancy)
IGF Binding Protein-1 (IGFBP - 1) During Pregnancy
IGFBP-1 is present at high concentrations in amniotic fluid (the fluid surrounding the baby in the womb) and in foetal and maternal circulation. During pregnancy, this test may be used to identify women at high risk of developing pre-eclampsia. It is also used to detect premature rupture of membranes (PROM), where the sac of fluid around the baby breaks before labour begins.
IGF Binding Protein-1 (IGFBP - 1) for Chronic Disease Monitoring
IGFBP-1 levels can help monitor insulin responsiveness over time in patients managing chronic metabolic conditions. The test may also be used to detect insulin-producing tumours, track acute changes in insulin action, and determine whether poor blood sugar control is due to inadequate insulin treatment or poor dietary management.
How to Prepare and What to Expect
Preparing correctly for the IGFBP - 1 test procedure is essential for accurate results.
Do You Need to Fast?
Yes, a 12-hour overnight fast is required before this test. Eating raises insulin levels, which in turn causes IGFBP-1 levels to fall significantly, sometimes by four to five times. Fasting ensures the sample reflects a reliable baseline measurement. If your doctor has ordered other tests alongside this one, confirm with them whether additional preparation is needed.
Practical Tips Before Your Test
Keep the following points in mind before your sample is collected:
- Avoid alcohol the night before the test
- Drink water normally; staying hydrated helps with sample collection
- Avoid strenuous exercise on the day of collection
- Inform your doctor about all medications, supplements, and vitamins you are taking (biotin supplements in particular may affect some assay methods)
- Morning collection is strongly preferred, as IGFBP-1 levels are naturally highest early in the day and drop through the evening
Step-by-Step Procedure
Here is what to expect during the IGFBP - 1 test procedure:
- Your identity is confirmed and your fasting status is verified before collection begins.
- A tourniquet (an elastic band) is applied to your upper arm to make the vein more visible.
- A small amount of blood (approximately 3 ml) is drawn from a vein using a fine needle into a serum gel tube (yellow top).
- The needle is removed and gentle pressure is applied to the collection site.
- The sample is processed promptly: the blood is spun in a centrifuge to separate the serum, which is then refrigerated or frozen for transport.
- The sample is dispatched to the laboratory, where it is analysed using an EIA (enzyme immunoassay) method.
Factors That Can Affect Accuracy
- Fasting status (the most critical factor; eating before the test can significantly lower IGFBP-1 levels)
- Time of day (morning samples are preferred due to diurnal variation in IGFBP-1 levels)
- Recent meals or elevated insulin levels
- Haemolysed (broken red blood cells) or lipaemic (excessively fatty) blood samples are not acceptable
- Biotin supplementation may interfere with some assay methods
Understanding Your IGF Binding Protein-1 (IGFBP - 1) Results
Your doctor will review your results alongside your symptoms, medical history, and other test findings. The table below shows general reference ranges for this test.
| Parameter | Normal Range | Unit |
|---|---|---|
| IGFBP-1 (Adults, fasting) | Approximately 10 to 50 | ng/mL |
| IGFBP-1 (Liver disease patients) | Significantly elevated (100 to 500+) | ng/mL |
Disclaimer: These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
IGFBP-1 is unique in showing very rapid, large fluctuations in response to food and insulin. Levels can vary more than tenfold in relation to meals, which is why fasting is critical. Insulin strongly suppresses IGFBP-1 production, while cortisol, glucagon, and certain other hormones stimulate it. During pregnancy, IGFBP-1 levels are naturally higher, particularly in amniotic fluid, and should be interpreted in that context.
How to Maintain Healthy Levels
These general wellness tips support stable insulin regulation, which in turn influences IGFBP-1 levels:
- Follow a balanced diet with consistent meal timings to keep insulin levels steady
- Engage in regular physical activity to support insulin sensitivity
- Maintain a healthy weight to reduce the risk of insulin resistance

Frequently Asked Questions
The IGF Binding Protein-1 (IGFBP - 1) test measures the level of IGFBP-1 in the blood, a protein that regulates the activity of insulin-like growth factors. It helps doctors evaluate conditions related to insulin resistance, growth hormone disorders, metabolic syndrome, and certain complications in pregnancy. Results are always interpreted alongside other clinical findings.
Eating raises insulin levels, and insulin strongly suppresses IGFBP-1 production. A meal can cause IGFBP-1 levels to drop by four to five times compared to fasting levels. A 12-hour overnight fast is therefore required to ensure the result reflects an accurate baseline.
Yes. The IGFBP - 1 test is used during pregnancy to identify women at high risk of pre-eclampsia. It is also used to detect premature rupture of membranes (PROM), as IGFBP-1 is present at high concentrations in amniotic fluid.
Women with PCOS often show low IGFBP-1 levels. This is thought to occur because high insulin levels in PCOS suppress IGFBP-1 production, which may in turn contribute to excessive androgen (male hormone) production. The test can support evaluation of hormonal imbalance in PCOS.
Morning collection is strongly preferred. IGFBP-1 levels are naturally at their highest early in the morning and decline through the day. Collecting the sample in the morning, after an overnight fast, gives the most reliable result.
This is a specialised test. At Lupin Diagnostics, the report is delivered within 23 days of sample collection. Please note that samples must be submitted by the 7th of the month, with reports expected 2 to 3 weeks after submission.
Yes, IGFBP - 1 test home collection is available through Lupin Diagnostics. A certified phlebotomist collects the blood sample at your home. The sample is correctly processed and transported to an NABL-accredited laboratory for analysis.
