A glucose meter, also referred to as a "glucometer", [1] is a medical device for determining the approximate concentration of glucose in the blood. It can also be a strip of glucose paper dipped into a substance and measured to the glucose chart.
Blood glucose monitoring is the use of a glucose meter for testing the concentration of glucose in the blood ().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'.
The Ames Reflectance Meter was the first blood glucose meter. It allowed patients with diabetes to self-monitor their blood glucose levels. The Ames Reflectance Meter was developed in 1970 by Anton H. Clemens. It had a needle that indicated the intensity of blue light reflected from a paper strip, called Dextrostix. The meter gave a ...
fingerprick type of glucose meter - need to prick self finger 8-12 times a day. continuous glucose monitor - the CGM monitors the glucose levels every 5 minutes approximately. Laboratory tests are often used to diagnose illnesses and such methods include fasting blood sugar (FBS), fasting plasma glucose (FPG): 10–16 hours after eating [1]
The test works by taking a small blood sample of blood using a lancet (a sterile pointed needle) to prick a finger (Image 1). The blood droplet is usually collected at the bottom of a test strip, while the other end is inserted in the glucose meter. [6] The drop of blood is drawn into the meter and can directly measure the glucose in the sample.
The YSI 2300 STAT PLUS Glucose and Lactate Analyzer (YSI 2300) was a Class II in-vitro diagnostics (IVD) automated analyser intended that measured glucose in whole blood, plasma or serum; and of L-lactate in whole blood, plasma, or cerebrospinal fluid (CSF).
A scatterplot is generated, plotting values from the reference glucose meter (x-axis) against values from the new device (y-axis); thus, each point represents measurement of a single sample by two methods. Grid lines are then drawn to indicate 5 different classifications (Regions A-E) based on clinical relevance:
Currently approved CGMs use an enzymatic technology which reacts with glucose molecules in the body's interstitial fluid to generate an electric current that is proportional to glucose concentration. Data about glucose concentration is then relayed from a transmitter attached to the sensor to a receiver and display that shows the data to the user.
