A blood glucose test measures the amount of a sugar, called glucose, in a sample of your blood.
Glucose is a major source of energy for most cells of the body, including those in the brain. The carbohydrates you eat eventually end up as glucose in the blood.

Glucose test - urine

How the test is performed
Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tu...
The first thing I did after reading the new study that caffeine can increase our blood glucose level was to switch to drinking green tea. The second thing I did was to switch again -- this time to decaffeinated green tea. I overreacted. Several years ago I had switched from coffee to Darjeeling tea, which has about half the caffeine per cup. While green tea has even less, I don’t like it much and only drink it rarely. I disliked the decaffeinated green tea so much that I threw out the package after taking the first sip. Now, I’m almost entirely back to Darjeeling tea. People call it a black tea, although it is light-colored and is technically more oolong than black and is therefore lower in caffeine than true black teas. While I control my blood glucose level, I’m not a purist. I have to enjoy everything that I eat or drink. While my diet includes no starch, sugar (no sucrose or high-fructose corn syrup), salt, or alcohol, except occassionally when I eat out, I don&rsqu...
For a loved one with diabetes, monitoring blood glucose levels is crucial. “Self-monitoring of blood glucose (SMBG testing) provides a map that guides decisions and changes in treatment components to improve diabetes control,” says Susan McLaughlin, American Diabetes Association president-elect, Health Care and Education. “Tracking patterns helps individuals know when they’re at greatest risk of very high or very low blood glucose, which can increase the risk of falls, result in fracture, decrease mobility , diminish quality of life, and lead to depression.” Today’s blood glucose monitors are portable, accurate, and reliable. Test results are sometimes reported in as little as five seconds, and almost always in less than a minute. Some are easier to use than others, require less blood for testing, and store more data. Error codes, automatic timers, and barcodes make calibrating the units less complicated, and large display screens allow people with l...
