Medical Tests FAQs

How do doctors test for diabetes?

The initial test a GP will often do is a urine test to look for glucose in your urine. If this is positive, the doctor will then arrange blood tests, which may include a Blood Glucose and HbA1c.

Blood Glucose = Blood Sugar Level

HbA1c = A marker for how high your blood sugar has been on average for the past 2-3 months.

What is a fasting blood glucose?

Blood Glucose level increases following a meal in everyone, whether you are diabetic or not. Hence Blood Glucose measurement may be skewed if it is taken soon after a meal. To prevent this doctors sometimes perform what is called a Fasting Blood Glucose test, where you are asked not to eat anything for 8-10 hours before the test. You can drink water. The test is usually done first thing in the morning at your GP surgery, so that it means you just miss your breakfast. 

What is a normal blood glucose level?

A normal fasting blood glucose is between 4-7mM.

A normal Random Blood Glucose level is 4-11mM (needs to be taken at least 2 hours after eating).

How do you test for diabetes at home?

The simplest test is a urine test which you can perform easily at home to screen for glucose in your urine. You can buy Urine Glucose Test Strips from Valuemed, under the section Medical Tests. If you detect glucose in your urine you should make an appointment with your GP.
