Many people with diabetes test their own blood glucose at home. Experts warn that there are many things to be aware of when measuring blood glucose, and a lack of attention may affect the accuracy of the test. Diabetic patients must learn to read the instructions of various devices for measuring blood glucose, otherwise some inappropriate practices may affect the accuracy of the patient’s blood glucose measurement. For example, the test strips used by diabetic patients for rapid blood glucose measurement require high storage conditions, and if you forget to close them after opening them, they may become damp and affect the accuracy of blood glucose measurement. Moreover, it is better to pack the test paper separately and not to put the cotton swab, alcohol, etc. and test paper into a jar. Experts also remind that when collecting fingertip blood to measure blood glucose, we should also pay attention to the fact that the nerve endings in the middle of the finger are rich, which is more painful when collecting blood, while the nerve endings on the side of the finger are less, so blood can be collected on the side of the finger when collecting blood. Moreover, when collecting fingertip blood, you should not squeeze your finger in order to collect enough blood faster, otherwise the blood collected will not only be blood in capillaries, but may contain tissue fluid, which will have a diluting effect and may affect the accuracy of blood glucose measurement.
