It is important for people with diabetes to monitor their blood sugar levels. Glucose is the type of simple sugar that the cells use for energy. In people with diabetes blood glucose levels is elevated. Blood sugar test is done to measure the amount glucose, present in your blood.

 

Your doctor may recommend measurement of;

  • Fasting blood glucose (done in the morning before you eat or drink anything even tea or coffee).
  • Random blood glucose (done at any time of the day)
  • Post-prandial blood glucose (is done 2 hours after eating)

The results of these tests are mostly ready in 1 to 2 hours. To measure the amount of glucose present in your blood---blood is drawn from a vein. Blood is usually drawn from the veins present inside the elbow or on the back of the hand. The reading on doing glucose level testing by blood sample taken from your vein (called a blood plasma value) and checked by finger prick test can differ a little.

 

Normal blood glucose levels;

  • Fasting blood glucose: 70-99 milligrams per deciliter (3.9-5.5 mmol/L)
  • 2 hours after eating (postprandial): 70-145 mg/dL (3.9-8.1 mmol/L)
  • Random blood sugar: 70-125 mg/dL (3.9-6.9 mmol/L)

The results of blood sugar levels can vary slightly from lab to lab. Blood sugar levels can be affected by many conditions. The most common cause of high blood sugar is diabetes. If your blood sugar levels are elevated your doctor may recommend re-testing of sugar levels and if required other tests. DO not ignore if your blood test results are abnormal.
