HOMA-IR (Insulin Resistance Index)
Here’s what it reflects — and what to do about it.
Longetic pulls together every lab and record you’ve had, follows how HOMA-IR (Insulin Resistance Index) changes over time, and explains what’s shifting — so you walk into your next appointment prepared, with reminders for retests along the way.
What is HOMA-IR (Insulin Resistance Index)?
A calculated score that estimates insulin resistance by combining your fasting blood sugar and fasting insulin results.
HOMA-IR is not a lab measurement on its own; it is a number worked out from your fasting glucose and fasting insulin values. A higher score can be associated with insulin resistance, meaning cells respond less well to insulin, which is often seen before blood sugar itself rises. Because it is an estimate used mainly in research and extended panels, it is best viewed as a trend alongside other results rather than a standalone diagnosis.
What to know about HOMA-IR (Insulin Resistance Index)
Understanding HOMA-IR (Insulin Resistance Index) means knowing what it reflects, what tends to move it, and the signs that suggest it’s worth a closer look — so you can bring the right questions to your next appointment.
