Semilente Insulin, Serum/Plasma — Mass Concentration
A blood test that measures semilente insulin, an older intermediate-acting insulin formulation; timing after a dose is important for interpretation.
["This test measures the amount of semilente insulin in blood, with results interpreted according to dose and collection timing."]

What is this test?
This test measures the concentration of semilente insulin in serum or plasma. Semilente is an older intermediate-acting insulin preparation, and the result may reflect insulin administered as a specified dose.
Why might I need this test?
A clinician may order this test to evaluate insulin levels, assess glucose regulation, or follow the response to semilente insulin. It may also help distinguish insulin produced by the body from certain insulin preparations.
How is the test performed?
A blood sample is drawn and analyzed in the laboratory to determine the insulin concentration. The laboratory may use an immunoassay or another validated method.
How do I prepare for the test?
Follow the laboratory and prescribing clinician's instructions about fasting and timing. If you take semilente insulin, record the dose and exact time of the injection, because the blood sample is often collected at a specific interval after the dose.
Reference range
Fasting: 2.6-24.9 μIU/mLN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Higher insulin values can occur after an insulin dose, with insulin resistance, or in conditions involving excess insulin production. Lower values may occur when insulin is not being produced adequately or when the measured level does not reflect the administered formulation. Results should be interpreted with blood glucose, symptoms, medication timing, and other relevant tests rather than used alone to diagnose a condition.
