Question

Quizplus · Accepted Answer

Blood glucose point-of-care testing (POCT) instruments work on the principle of both reflectance of color intensity and electrical potential of the glucose reaction. The instrument measures the amount of glucose in a blood sample by detecting a change in color or electrical charge that occurs when an enzyme in the test strip reacts with glucose. The intensity of the color or electrical charge is then measured and converted into a blood glucose level.
