A gray sodium fluoride micro blood collection tube is a blood collection tube with a specific purpose.
1. Appearance characteristics
Usually has a gray tube cap, which is easy to identify. The tube body is generally made of transparent material, which is convenient for observing the amount and state of the collected blood.
The tube contains sodium fluoride. Sodium fluoride mainly plays a role in inhibiting glycolysis. After the blood sample is collected, the glycolysis process in the blood cells may continue even in an in vitro environment, which will cause the blood glucose concentration to gradually decrease. Sodium fluoride can effectively inhibit the activity of glycolytic enzymes, thereby stabilizing the glucose concentration in the blood and ensuring that the test results accurately reflect the true blood glucose level in the patient.
Scope of application
Blood glucose testing: Mainly used in situations where accurate blood glucose concentration needs to be determined, especially for some patients who need to monitor blood glucose changes for a long time, such as diabetic patients. Gray sodium fluoride micro blood collection tubes can provide stable samples for blood glucose testing and reduce detection errors caused by glycolysis.
Other metabolite detection: In some test items that require simultaneous detection of other metabolites related to sugar metabolism, this blood collection tube may also be used to ensure the accuracy of the test results.

What is a Micro Capillary Tube?

A micro blood collection tube is a container for collecting small amounts of blood samples.
Its main features are as follows:
Small and portable: usually small in size, easy to carry and operate, suitable for occasions where a small amount of blood sample is needed for testing.
Accurate collection: can accurately collect trace amounts of blood, reducing the discomfort caused to patients by collecting too much blood, especially suitable for infants, the elderly, and weak patients who have difficulty in blood collection.
Wide range of uses: It is used in clinical testing, medical research, and other fields. It can be used for a variety of testing items such as blood routine, biochemical index testing, coagulation function testing, etc.
