Clinicians order insulin to see how your pancreas is working and how your body responds to sugar. It can help explore low blood sugar episodes, possible insulin resistance, or guide diabetes treatment decisions. Results are usually reviewed with glucose-based tests for context. You can test this marker with Aniva across Germany and Finland.

High: Can appear after eating, with insulin resistance, obesity, or certain medicines; rarely from an insulin-producing tumor.
Low: May occur with reduced pancreatic production, during fasting, or after some diabetes treatments. Pairing insulin with glucose helps show whether your body is making enough and using it well. Using insulin alone to diagnose insulin resistance is not guideline-endorsed; there are no standardized cutoffs.
Common factors include recent meals or sugary drinks, insulin or diabetes pills, steroids, birth control pills, and stress. Intense exercise, alcohol, acute illness, pregnancy, and kidney or liver problems can shift levels. High-dose biotin (vitamin B7) supplements may interfere with some lab methods.
Special situations: suspected insulinoma, recurrent hypoglycemia, or pregnancy may need repeat, fasting, or timed tests; confirm unexpected results with your clinician.
What do my insulin results mean? Higher levels can mean your body is making more or needs more insulin. Lower levels can mean less production. Results make the most sense alongside glucose.
Do I need to fast for this test? Fasting is not required, but consistent timing helps compare results. Your clinician may request a fasting sample.
What can affect my results? Meals, insulin or diabetes pills, steroids, biotin supplements, hard exercise, stress, illness, and pregnancy can all shift levels.
How often should I test insulin? Only as advised. It’s often checked when adjusting treatment or evaluating symptoms and paired with glucose or HbA1c.
How long do results take? Most labs report within 1–3 business days.
What should I discuss with my clinician? Share all medicines and supplements, your symptoms, and recent meals. Ask whether fasting or additional tests are needed.
