What is this test?
This test evaluates regular insulin, a fast-acting form of insulin. Depending on the order, it may report an administered dose or measure regular insulin in a laboratory specimen.
Why might I need this test?
Your clinician may use it to review insulin dosing, assess timing after an injection, or guide changes in diabetes treatment. It may be ordered when a blood insulin measurement is needed or when regular insulin use is being monitored.
How is the test performed?
If a laboratory measurement is ordered, a specimen is collected and analyzed with a validated insulin assay. If the result is a dose record, the information comes from your medication administration record; your care team can clarify which applies.
How do I prepare for the test?
Follow your clinician’s instructions about fasting and the timing of your insulin injection. Bring an updated medication list, and do not change your insulin dose unless your clinician tells you to do so.
Reference range
INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A
Inform your healthcare provider if you are taking blood thinners. No special preparation required.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Regular insulin levels can vary with the administered dose, injection timing, meals, and individual absorption. Results that are higher or lower than expected may prompt review of dosing, injection technique, meal timing, or factors affecting insulin clearance.
