Frequently Asked Questions

What is the Insulin Free (Bioactive) Test?
It is a blood test that measures the bioactivity of insulin, providing a more accurate assessment of how well insulin is functioning in the body to regulate blood sugar levels.
How is this test different from a regular insulin test?
Unlike regular tests that measure insulin concentration, this test evaluates insulin's functional activity by assessing its binding to receptors, offering better insight into insulin resistance or deficiency.
Why is fasting required for this test?
Fasting ensures that blood sugar and insulin levels are at baseline, allowing for accurate measurement of insulin bioactivity without interference from recent food intake.
How long does it take to get results?
Results are typically available within 2-3 weeks after sample collection, as the test may require specialized processing.
What is the cost of the test in India?
The test costs INR 13,000 at DNA Labs India, which includes home sample collection services across major cities.

Who should take this test?
It is recommended for individuals with diabetes symptoms, those on insulin therapy, or anyone needing detailed assessment of insulin function for diabetes management.
What do the results indicate?
Results indicate insulin bioactivity levels. High levels may suggest insulin resistance, low levels may indicate insulin deficiency, and normal levels suggest adequate insulin function.
Are there any risks associated with the test?
The test is a simple blood draw with minimal risks, such as minor bruising or discomfort at the puncture site.
How do I prepare for the test?
Prepare by fasting overnight for 8-12 hours and ensuring you have the required consent form filled out before sample collection.
