Disposable Negative Pressure Vacuum Blood Collection Tube, Sodium Fluoride Tube, Glucose Tube, Grey Cap, Glass Pet ISO13485 ODM OEM

The primary function of the single-use negative pressure sodium fluoride tube vacuum blood collection tube (glucose tube) is to collect and preserve blood samples, especially for glucose determination. This type of blood collection tube contains sodium fluoride, which is a weak anticoagulant that helps prevent glucose degradation. Specifically, sodium fluoride can inhibit the activity of glycolytic enzymes in the blood, thereby slowing down the consumption of glucose and maintaining stable glucose levels in the blood sample over a longer period.

Additionally, these tubes usually contain heparin sodium, another anticoagulant that prevents blood coagulation, making it easier to separate serum or plasma from the blood sample for subsequent glucose determination. Heparin sodium also addresses hemolysis issues, further ensuring the quality of the blood sample.

Functions include:

Preventing glucose degradation: Through the action of sodium fluoride, this slows down glucose consumption and maintains stable glucose levels.
Preventing blood coagulation: By preventing blood coagulation through heparin sodium, it facilitates the separation of serum or plasma.
Maintaining blood sample quality: Ensures that the blood sample remains in its original state for an extended period, facilitating subsequent glucose determination and other related tests. These characteristics make this type of blood collection tube particularly suitable for testing projects requiring long-term stability of blood samples, such as glucose determination and glucose tolerance tests.
