In March 2001, the U.S. Food and Drug Administration (FDA) approved a noninvasive blood glucose monitoring device for adults with diabetes.
Noninvasive monitoring means checking blood glucose levels without puncturing the skin for a blood sample.
The GlucoWatch Biographer, manufactured by Cygnus Inc., was approved to detect glucose level trends and patterns in adults age 18 and older with diabetes.
It must be used along with conventional blood glucose monitoring of blood samples.
The device, which looks like a wristwatch, pulls body fluid from the skin using small electric currents.
It checks blood glucose levels every 20 minutes.
Over the years, scientists have been trying to find noninvasive ways for people with diabetes to measure their blood glucose.
Most methods of monitoring blood glucose require a blood sample, usually obtained by using an automatic lancing device on a finger.
Some meters use a blood sample from a less sensitive area, such as the upper arm, forearm, or thigh.
Some devices use a beam of light instead of a lancet to pierce the skin.
