Eventually, the EGA became accepted as one of the “gold standard” techniques for determining the accuracy of blood glucose meters. To perform the analysis, blood glucose samples are obtained and each sample is divided and measured by two meters: a "reference method" (a meter or laboratory test known to produce accurate results); and a new ...
Fasting prior to glucose testing may be required with some test types. Fasting blood sugar test, for example, requires 10–16 hour-long period of not eating before the test. [1] Blood sugar levels can be affected by some drugs and prior to some glucose tests these medications should be temporarily given up or their dosages should be decreased.
Glucose vs. plasma glucose: Glucose levels in plasma (one of the components of blood) are higher than glucose measurements in whole blood; the difference is about 11% when the hematocrit is normal. This is important because home blood glucose meters measure the glucose in whole blood while most lab tests measure the glucose in plasma.

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 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 glucose tolerance test was first described in 1923 by Jerome W. Conn. [4]The test was based on the previous work in 1913 by A. T. B. Jacobson in determining that carbohydrate ingestion results in blood glucose fluctuations, [5] and the premise (named the Staub-Traugott Phenomenon after its first observers H. Staub in 1921 and K. Traugott in 1922) that a normal patient fed glucose will ...
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 ...
