What This Test Measures
This test detects insulin in your bloodstream as it is delivered through an insulin pump. It helps confirm whether insulin is being absorbed correctly and at the expected rate. The test may also be used to troubleshoot issues like pump malfunctions or improper catheter placement.
Why It’s Done
Doctors may order this test if you’re using an insulin pump and suspect issues like insufficient insulin delivery, pump failure, or incorrect settings. It can also be part of routine monitoring to ensure your diabetes management plan is working as intended.
How It Works
A small blood sample is taken, typically from your arm. The sample is analyzed using an immunoassay method to detect insulin levels associated with pump delivery. The result is qualitative (positive/negative) rather than a numeric measurement.
What to Expect Before the Test
No special preparation is needed, but inform your healthcare provider about any medications or recent changes in your insulin pump settings. Avoid eating or drinking for 2–4 hours before the test if instructed.
Reference range
Fasting: 2.6-24.9 μIU/mLN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Positive results indicate insulin is being delivered as expected, confirming proper pump function. Negative results may signal issues like pump failure, blocked catheter, or incorrect insulin settings. This test helps prevent hypoglycemia or hyperglycemia by identifying delivery discrepancies early.
