Understanding the test
What does the Fasting Insulin test measure?
Also called Fasting Insulin
A baseline insulin measurement can help assess the relationship between fasting glucose and the insulin required to maintain it. Exact fasting status matters.
When it may be requested
Endogenous hormone response
A clinician may assess how much insulin circulates while no meal is being absorbed.
Comparing glucose and insulin
The relationship between the two can provide context in a specialist assessment.
Before your sample
Prepare for collection
SpecimenSerum
Your checklist
Overnight fasting is required. Confirm the timing of insulin or other diabetes medicines with the prescribing clinician before the appointment.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

Reading your result
A high value with normal glucose may have a different explanation from an insulin value obtained during low glucose. Medicines and assay differences also matter.
What can affect it
- Fasting insulin alone is not a diagnostic test for diabetes.

Patient questions
Before you book
Why can the same insulin level have different meanings?
A person whose glucose is low would normally have a different insulin response from someone whose glucose is raised. That is why the paired glucose is important.
Why must I fast so strictly for this one?
Insulin responds to food within minutes and far more sharply than glucose does. Even a small sweetened drink or a milky coffee can lift the reading enough to make it uninterpretable.
Do I need a fasting insulin test as part of routine PCOS care?
Insulin resistance is common in PCOS, but a fasting insulin level is usually not needed for routine PCOS care. If the concern is prediabetes or diabetes, ask which glucose test answers that question. The international PCOS guideline favours the 75 g glucose tolerance test when feasible.
