Glucose - description and reference ranges

What is it?

Glucose concentration levels help diagnose and monitor diabetes or hypoglycaemia (low blood glucose), as well as hyperglycaemia (high blood glucose). It is important to monitor this biomarker over time, as it is fairly sensitive to day-to-day changes in food intake.

Reference ranges

If your indicative glucose concentration is lower than the reference range for our laboratory:

This can mean hypoglycaemia. Some of the signs of a low blood sugar level include trembling, sweating, dizziness and a fast heartbeat.

If you have diabetes, the main cause of a low blood sugar level is diabetes medicine, skipping meals or intense exercise.

You can discuss this result with your GP.

If your indicative glucose concentration is higher than the reference range for our laboratory:

Hyperglycaemia is a condition where the level of sugar/glucose in your blood is too high. It is usually seen in people with diabetes.

Symptoms include feeling thirsty all the time, passing urine very frequently, tiredness and fatigue.

You need to be cutting down on sugary food and drink. In addition, stress, ilness or eating too much and lack of exercise can lead to elevated glucose levels.

You can discuss this result with your GP.

    The PSA Blood Test and Prostate Cancer Screening

    In the UK, we screen for many different conditions. This starts before we are even born when foetuses are screened for conditions such as Down’s syndrome then, in the new born period, babies are screened for metabolic diseases and hearing problems, school children are screened for colour blindness, and in adulthood we are screened for breast cancer, cervical cancer, and bowel cancer. But we don’t screen for prostate cancer despite the existence of a simple blood test that can alert us to the possibility of the disease.
