Brother Sugar: Older sister, I heard that blood glucose meters are not allowed to measure blood glucose? Sugar sister: impossible, the hospital is not also using this blood glucose meter to measure blood sugar? Is this true? Since the introduction of the rapid blood glucose meter in 1970, patients can test their own blood glucose and see the results immediately, which has brought great convenience to diabetic patients. The blood glucose measured by the rapid blood glucose meter is different from the intravenous blood glucose, because the blood glucose meter detects the capillary whole blood glucose, while the intravenous blood glucose measures the plasma sugar. Since whole blood contains red blood cells, which contain less glucose, the measured value is lower, generally considered to be about 12% lower. For the convenience of calculation, it is roughly calculated according to l0%, that is, the capillary whole blood glucose value plus l0%, which is roughly equivalent to the venous blood glucose value. In addition, fasting and postprandial also differ because of different arterial and venous blood glucose. For the same patient to monitor blood glucose for a long time, all these factors can be neglected. When using the blood glucose meter, pay attention to the correct operation, disinfect your fingers with alcohol, and wait for the alcohol to dry completely. When squeezing blood, the force should not be too strong, which will squeeze out the inter-tissue fluid and dilute the blood, and the measured blood glucose value will be low. In addition, the test paper should not be damp and expired. Some blood glucose meters are also affected by temperature. The blood glucose meter is accurate and recommended for clinical monitoring of blood glucose control of diabetic patients.
