What is this test?
This test measures the amount of insulin and cholesterol in a blood sample. Insulin helps regulate blood sugar, while cholesterol is a substance used by the body that is also associated with cardiovascular risk.
Why might I need this test?
A clinician may order this test when evaluating diabetes, insulin resistance, metabolic syndrome, or high cholesterol. The results may also help guide nutrition, exercise, and medication decisions.
How is the test performed?
A blood sample is collected and analyzed in a laboratory. The sample may be taken from a vein and tested as serum or plasma, depending on the laboratory method.
How do I prepare for the test?
Follow the preparation instructions provided by your clinician or laboratory. If fasting is required, avoid food and drinks other than water for the specified period. Do not change insulin or other medication schedules unless your clinician tells you to do so.
Reference range

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.
Insulin and cholesterol are interpreted together with other findings, such as blood glucose, medical history, and medication use. Elevated insulin can occur with insulin resistance or metabolic syndrome, while elevated cholesterol may indicate increased cardiovascular risk. Results that are unexpectedly high or low should be reviewed by a healthcare professional because diet, activity, illness, and medications can affect them.
