A blood sugar test is a procedure that measures the amount of sugar or glucose in the blood. You should reserve a blood sugar test as part of a routine checkup, you may also be looking to see if you have diabetes or prediabetes, a condition in which your blood sugar levels are higher than normal.
The main types of blood tests for diabetes include:
Fasting blood sugar test: fasting blood sugar tests involve having blood drawn after fasting overnight, which usually means you should not eat for 8 to 12 hours:
Hemoglobin A1C test: This test measures the amount of sugar attached to red blood cells, which generally have a shelf life of three months. Therefore, this test measures how high your blood sugar level has been in recent months.
Average blood sugar level: a blood sugar test is done regardless of the last time you ate a meal.
Urine test: the body produces ketone bodies when fat tissue is used to obtain energy instead of blood sugar.
Laboratories can examine urine for these ketone bodies. If ketone bodies are present in moderate to large amounts in the urine, this could indicate that your body does not produce enough insulin.
