Diabetes and blood testing


Testing blood glucose (sugar)


When first diagnosed with diabetes, many people hear the words blood glucose (sugar) testing for the first time. Once you have a blood glucose meter and test strips, and you know the blood glucose testing routine, you may have questions about when to test, how often, and why it is important for good diabetes care.

Type 1 and Type 2 diabetes and blood sugar testing


Depending on your diagnosis, you may not be asked to blood test at all. There is no hard and fast rule about how often one should test as it depends on your type of diabetes, for example if you have Type 1 or Type 2 diabetes, and even then different people will have different regimes.


You should discuss how often to test with your diabetes nurse or GP, as they will be able to advise you depending on which medication you are taking and what your blood glucose levels are. Your diabetes nurse and GP will also be able to advise you on blood testing during illness, strenuous activities and while driving. If you are unsure, talk to your diabetes nurse or GP.​
