INSULIN, RANDOM

The insulin random test is a diagnostic tool to determine the level of insulin in the blood without the need for fasting, as it can be done at any time. The insulin random test is basically examining insulin resistance of the body. It is a simple, quick, affordable and effective test for determining the insulin, which is why an insulin random test is recommended by the doctor. Random insulin tests provide understanding of how effectively your body uses insulin. Insulin resistance is a metabolic issue that can develop conditions such as prediabetes, obesity, type 2 diabetes and polycystic ovary syndrome (PCOS).

What Is an Insulin Random Test?

An insulin random test determines the content of insulin in the blood regardless of what food you have consumed because it checks insulin at a specific moment. As insulin levels fluctuate throughout the day. The reports are understood based on glucose levels and clinical history. If insulin levels come very high it may signal that the body is producing more insulin to overcome insulin resistance.

Doctors often recommend this test alongside:

• Random blood glucose
• C-peptide test
• OGTT (Oral glucose tolerance test)
