Test times vary from 5 seconds to 2 minutes (modern meters typically require less than 15 seconds).Ī blood glucose meter is an electronic device for measuring the blood glucose level. Blood glucose meters įour generations of blood glucose meter, c. This might include diet adjustments, exercise, and insulin (as instructed by the health care provider). Īlso, testing allows for a quick response to high blood sugar ( hyperglycemia) or low blood sugar ( hypoglycemia). The Mayo Clinic generally recommends that diabetics who use insulin (all type 1 diabetics and many type 2 diabetics) test their blood sugar more often (4–8 times per day for type 1 diabetics, 2 or more times per day for type 2 diabetics), both to assess the effectiveness of their prior insulin dose and to help determine their next insulin dose.īlood glucose monitoring reveals individual patterns of blood glucose changes, and helps in the planning of meals, activities, and at what time of day to take medications. Most people with type 2 diabetes test at least once per day. Healthcare professionals advise patients with diabetes mellitus on the appropriate monitoring regimen for their condition. Measurements may occur after fasting or at random nonfasting intervals ( random glucose tests), each of which informs diagnosis or monitoring in different ways. Skin-prick methods measure capillary blood glucose (i.e., the level found in capillary blood), whereas CGM correlates interstitial fluid glucose level to blood glucose level. Different manufacturers use different technology, but most systems measure an electrical characteristic and use this to determine the glucose level in the blood. The other main option is continuous glucose monitoring (CGM). Particularly important in diabetes management, a blood glucose test is typically performed by piercing the skin (typically, via fingerstick) to draw blood, then applying the blood to a chemically active disposable 'test-strip'. Blood glucose monitoring is the use of a glucose meter for testing the concentration of glucose in the blood ( glycemia).
