Diabetes is a chronic, slow-progressing debilitating condition. One of the tests that are performed to monitor blood sugar levels in this condition is the Insulin-Fasting test.
What is Insulin-Fasting test?
The Insulin-Fasting test is generally suggested when there two or more tests to show low blood sugar levels:
- It is suggested in people suffering from conditions like PCOS, Type-2 diabetes, heart diseases, or prediabetes.
- A periodic Insulin-Fasting test may be recommended in some people.
An Insulin-Fasting test is often performed along with a Glucose-Fasting test.
Why is an Insulin-Fasting test suggested?
The Insulin-Fasting test is performed to detect insulin levels in the blood in order to
- Detect tumors in the Islets of Langerhans in the pancreas.
- Determine the cause of low blood sugar levels.
- Determine insulin resistance.
How is an Insulin-Fasting test performed?
An Insulin-Fasting test is performed in the following steps:
- The area on the forearm for the prick is cleaned with an antiseptic.
- A tight elastic band [tourniquet] is tied above the area of the intended puncture.
- Blood is collected from a vein using a needle and syringe.
The collected blood is then sent for an Insulin-Fasting test.
What are the parameters measured in an Insulin-Fasting test?
The Insulin-Fasting test measures the following parameters:
- High insulin levels indicate insulin resistance.
- Low levels indicate insufficient beta cells producing insulin.
- Normal or high levels indicate hypoglycemia.
Preparation before performing an Insulin-Fasting test
For an Insulin-Fasting blood test, the patient has to arrive for the test after fasting for a minimum of 8 hours.
Post-care after an Insulin-Fasting test
Post-care measures after an Insulin-Fasting test include:
- Eating food after fasting.
- Referring to the physician along with the reports.
Sample types in an Insulin-Fasting test
The Insulin-Fasting test is performed using a blood sample.
Side effects/risks of an Insulin-Fasting test
There are no side-effects/risks of an Insulin-Fasting test. However, fainting, dizziness, and pain may occur in the area of the prick. Excessive bleeding may also occur.
