A visual guide that correlates the color change on a reagent-impregnated strip after exposure to a glucose-containing sample, such as blood, with an estimated glucose concentration. The intensity of the color development on the strip, when compared to the reference colors, enables a user to approximate the glucose level. This process is often employed in self-monitoring of blood glucose, particularly by individuals with diabetes.
This reference tool provides a convenient and inexpensive method for estimating glucose concentrations, offering immediate feedback to the user. Historically, such charts played a significant role in diabetes management before the widespread availability of digital glucose meters. The ability to quickly assess glucose levels enabled individuals to make informed decisions regarding diet, exercise, and medication adjustments. While digital meters offer greater accuracy, the color-based method remains relevant in resource-limited settings and as a backup option.
