A Brief About the Blood Tests for Diabetes

Diabetes is a long-lasting or chronic health condition which affects how a person’s body converts food into energy. Most of the food you consume is broken down into glucose or sugar and released into the bloodstream. The pancreas is signalled to release insulin when the blood sugar goes up. Insulin lets the blood sugar into the cells of your body so that it can be used as energy.

If a person has diabetes, their body either doesn’t produce enough insulin or is not able to use the insulin it produces as well as it should. When there is not an enough insulin or when the cells cease to respond to insulin, your bloodstream ends up with too much blood sugar. Over time, this can lead to serious health problems, such as kidney diseases, vision loss, and heart disease.

There are many tests for diabetes. These tests can be categorised into blood tests, urine tests, and gestational tests. Here, we talk in brief about the blood tests for diabetes.

  1. The A1c Test

Blood tests help a doctor determine the blood sugar levels in the body. The A1c test is a common test as its results provide an estimation of the blood sugar levels over time and one does not need to fast before the test. The test is also called the glycated haemoglobin test. It measures the amount of glucose that has attached itself to your body’s red blood cells over the last 2 to 3 months.

  1. Fasting Blood Sugar Test

In a fasting blood sugar test, your blood is drawn out after you have fasted overnight (typically that means not eating for 8-12 hours).

  1. Oral Glucose Tolerance Test

The oral glucose test (OGTT) is carried out over a period of 2 hours. Initially, your blood sugar gets tested. Then, a sugary drink is given to you. After 2 hours, the levels of your blood sugar get tested again.

  1. Random Blood Sugar Test

In a random blood sugar test, the drawing of blood takes place at any given time, regardless of when you last ate.
