Blood glucose detection is a key test in medical diagnosis and physical examination. By analyzing the blood glucose level of patients, doctors can determine whether there is a situation such as elevated blood glucose or diabetes. However, the accuracy of blood glucose detection sometimes does not solely depend on instruments and technology, and the use of appropriate blood collection containers and anticoagulants is also crucial. In this regard, the role of EDTA-K2 cannot be ignored. Below, we will discuss the use of EDTA-K2 test tubes in blood glucose detection.

1、 The importance of blood sugar testing
Blood glucose detection is an important part of clinical medicine and laboratory research. It is used to diagnose diabetes, monitor diabetes patients, and evaluate blood glucose levels in other diseases. Moreover, blood glucose testing also plays a crucial role in scientific research, such as in glucose metabolism research, new drug development, and research related to disease risk.
2、 EDTA-K2 test tube blood glucose detection
EDTA-K2 test tube is a container used for blood collection, which contains ethylene diamine tetraacetic acid dipotassium salt (EDTA-K2) as an anticoagulant. Its main function is to bind calcium ions in the blood to prevent the occurrence of coagulation. However, when used in blood glucose testing projects, the EDTA-K2 test tube cannot be used alone and generally needs to be paired with sodium fluoride.
3、 The role of sodium fluoride
Sodium fluoride is an effective anticoagulant for blood glucose samples, and its main function is to inhibit sugar metabolism, especially the glycolysis process. Specifically, sodium fluoride can effectively prevent the action of enolase during enzyme glycosylation, which is one of the key steps in glycolysis. Enolase promotes the production of monophosphoglycerate from glucose, which prevents the formation of phosphoenolpyruvate and effectively inhibits the glycolysis process.

4、 Why does it need to be paired with sodium fluoride?
Blood glucose testing requires stable blood samples to ensure that the measured values accurately reflect the patient's physiological state. However, in blood without anticoagulation treatment, blood sugar can change in a short period of time, which can lead to inaccurate detection results. The addition of sodium fluoride can prevent the breakdown of sugar, maintain stable blood sugar concentration, and also prevent red blood cell rupture, helping to maintain the integrity of the blood sample.
When conducting blood glucose testing, selecting appropriate anticoagulants can ensure the effectiveness of the experiment. The combination of EDTA-K2 and sodium fluoride can inhibit sugar metabolism, ensure stable blood glucose concentration in blood samples, and obtain accurate test results.
