HOMA-IR test based on fasting glucose and insulin

Insulin resistance often develops gradually and without clear signals. A HOMA-IR test looks at the relationship between your fasting glucose and fasting insulin, so you get a picture of how your body handles sugar and insulin.

For women this is especially interesting, because insulin sensitivity is closely woven into your hormonal balance. Think of your cycle, your energy and symptoms that are sometimes linked to PCOS.

This insulin resistance test can be interesting if you are curious about how your body handles insulin. For example if you deal with energy dips, find it hard to lose weight, or have questions around PCOS.

Also if insulin resistance runs in your family, or if you simply want a factual starting point, an insulin test can give you a little more insight. You decide whether and when you want this measured.

This test looks at three related values in your blood:

• Glucose (Fasting): your blood sugar level after a period of fasting, a baseline measure of how your body processes sugar.
• Insulin (Fasting): the amount of insulin in your blood while fasting, showing how much effort your body puts into keeping your glucose stable.
• HOMA-IR: a calculated score based on your fasting glucose and insulin that can give an impression of your insulin sensitivity.

Together these three form the basis for your HOMA-IR score.

Your HOMA-IR score can give an impression of how sensitive your body currently is to insulin. A higher score may point to reduced insulin sensitivity, while a lower score can fit with normal sensitivity.

It remains a single snapshot and not a diagnosis. The outcome can help you look, together with a doctor, at what the numbers might mean in your situation.

This test requires a small blood draw at a certified lab. In the Netherlands you can choose from 700+ sample points, so there is often one near you.

After ordering, you pick a location and a moment that suits you. The draw usually takes only a few minutes, and you do not need a referral from your GP.

Measuring insulin resistance can be valuable at different moments, for example:

• when you have questions around PCOS or other hormonal symptoms
• when losing weight feels hard despite your efforts
• when you deal with cravings, energy dips or fluctuating blood sugar
• when you simply want a factual view of your insulin sensitivity

An insulin blood test like this gives you something tangible to work with.

Your result shows your fasting glucose, your fasting insulin and your calculated HOMA-IR score, each with a reference range. What counts as usual can vary slightly by laboratory.

A score within the range usually fits with normal insulin sensitivity, while a higher score may point to more insulin resistance. A doctor helps you place these numbers in the right context.

For a reliable HOMA-IR score it is important that you are fasting. That usually means eating nothing for around eight to twelve hours before the blood draw and drinking only water.

For that reason, it helps to plan your appointment in the morning, so you spend most of the fasting window while you sleep. When scheduling your draw you will find clear instructions about this.

Your result is usually available online within a few working days. Each value is shown clearly with a reference range and an explanation, so you understand what you see.

Every blood test result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
