It is a weak anticoagulant, usually combined with potassium oxalate or sodium iodate, the ratio of sodium fluoride 1 part, potassium oxalate 3 parts. This mixture of 4mg can make 1ml of blood non-coagulable and inhibit glycolysis within 23 days, and cannot be used for urease determination of urea, nor for alkaline phosphatase and amylase determination, and is recommended for blood glucose detection. It contains sodium fluoride or potassium oxalate or EDTA-Na spray, which can inhibit the enolase activity in glucose metabolism. After blood drawing, mix it upside-down for 5-8 times, and then centrifuge, take the supernatant plasma for backup. It is a special tube for rapid blood glucose determination.
