Measurements are just approximations and may vary for every manufacturer. ![]() At least 0.5 μl to 1 μl of blood is needed per reading. The meter measures glucose concentration through these electric currents. Instead of dyes, the glucose is converted into electrical current. The advent of electrochemistry in the ‘90s made test strips what they are today. An enzyme used in the early test strips convert the glucose in the drop of blood into dye the glucose meter shines a beam of light to the strip and detects how much light was absorbed by the dye. It was hard to operate and it needed a lot of blood. When test strips were first introduced in the early 1980s, the process was difficult for most people. ![]()
