What is Glucose Meter?

The blood glucose monitor is an instrument used to measure blood sugar, invented by Tom Clemens. At present, home blood glucose meters on the market are mainly divided into two categories: electrochemical method and light reflection technology.

How does Glucose Meters Work?

Blood glucose meters are mainly divided into two categories: electrochemical method and the photochemical method:

1. The electrochemical method uses the principle of detecting the current signal generated during the reaction to reflect the blood sugar level. The electrons generated by the reaction between enzyme and glucose pass through the current counting facility to read the number of electrons and then convert it into a glucose concentration reading.

2. The photochemical method is to detect the color change of the test strip during the reaction to reflect the blood sugar level. The intermediate produced by the reaction of enzyme and glucose is used to detect the intensity of the reflected light on the reflective surface of the test paper, and the intensity of the reflected light Converted into a glucose concentration.

What are the benefits of blood glucose monitoring?

Regular glucose monitoring is one-way people with diabetes can learn more about their condition. When it’s time to make important decisions about medication dosage, exercise, and diet, knowing your blood glucose levels will help you, your doctor, and the rest of your healthcare team.

By checking your blood glucose levels routinely, you’ll also know when your blood sugar is too high or too low, both of which can cause symptoms and serious health problems.

Your doctor will calculate the target range for your blood glucose based on your age, your type of diabetes, your overall health, and other factors. It’s important to keep your glucose levels within your target range as best as you can.

Why isn't blood sugar measured correctly? Here are a few things to keep in mind when measuring:

1. Blood sugar values that are not measured at the same time are not comparable. It is recommended that you test your blood sugar at home, or when comparing your data, try to keep it fixed at the same time every day.

2, Affected by insomnia, mood swings, and other reasons. None of the fasting blood sugar measured in these cases reflects the real situation and must be treated with the disease, rather than adjusting for sugar-lowering drugs.

3, Disinfectant improper selection, with iodine wine or iodine volt disinfection, the latter will react with the test paper, resulting in high test results. Therefore, blood should be sterilized with 75% alcohol, and wait for the alcohol to dry out before testing.

4, Blood harvesting method is not correct, if the amount of blood taken during the test is insufficient, will lead to test failure or low measured results, need to replace the test paper re-measurement. If the blood drop is too large, the overflow determination area will also affect the measurement results. It is recommended to take finger blood, needle depth should be appropriate, avoid squeezing fingers.

5, Before the test did not adjust the code. The code displayed by the blood glucose meter should be checked and adjusted before testing to match the code on the test strip box.
