Fluctuations in blood sugar can cause a number of symptoms. Get your levels tested today & find out the cause of your fatigue.

A blood sugar test is a fasting blood test that tests your levels of glucose, the body’s main source of energy. Glucose is circulated throughout the body after being broken down from carbohydrates in the diet & absorbed by the small intestine. Glucose is required by almost all of our cells in order to function properly.

This test determines your blood glucose levels & check whether they are within the normal range. This test is helpful in the diagnosis & monitoring of diabetes, & can also provide you with information regarding hypoglycaemia & hyperglycaemia (low & high levels of blood glucose).

When should I get tested?

The doctor may suggest you get a blood sugar test if you are at risk of diabetes, or are showing symptoms of hypoglycaemia or hyperglycaemia. This is also a routine test for those who already have a diagnosis of diabetes, & for pregnant women.

What does the test include

The blood sugar test is a fasting blood test.

What to Expect

Step 1

Preparing for test

Usually you need to go without food, & drink nothing except water, for the 8-10 hours prior to your test. Check in with us about this when you call to book your appointment, as if you already have diabetes, you may need to have the test after a meal.
Step 2

During the test

This test is either done using a drop of blood taken with a tiny pinprick in your finger, or from blood taken with a needle from your inner arm.
