Analysis of the causes of fogging when blood collection tube coagulant is sprayed on test tubes

The "misty film" on the inner wall of the blood collection tube is a natural result of the coagulant spraying process, formed by fine solid particles adhering to the tube wall after spraying and drying. The degree of haze mainly depends on the particle size of the coagulant raw material, and the larger the particle size, the more obvious the visual effect is usually. The uniform misty appearance is a direct reflection of good spray coating process control and can be used as a preliminary quality judgment, but the final quality still needs to be rigorously evaluated through laboratory performance testing.

Sodium fluoride, the 'guardian' of blood glucose testing, not a coagulant or anticoagulant

Sodium fluoride, the 'guardian' of blood glucose testing, not a coagulant or anticoagulant

Sodium fluoride is neither a coagulant nor an anticoagulant in vacuum blood collection tubes, and its core function is to resist blood glucose breakdown. It can inhibit blood cell glycolysis and stabilize the ex vivo blood glucose concentration. Usually used in combination with anticoagulant potassium oxalate to form a dual guarantee of "anticoagulation+stability", it is a key additive in blood glucose collection tubes (such as gray head tubes) specifically designed for blood glucose testing, ensuring the authenticity and reliability of blood glucose levels before testing.

Drying process of blood collection vessel coagulant: a key technology to ensure the accuracy of blood testing

Drying process of blood collection vessel coagulant: a key technology to ensure the accuracy of blood testing

The drying treatment of coagulants is a key process to ensure the accuracy of blood testing. Undried coagulants can cause differences in clotting time and test results due to residual moisture diluting the sample, uneven distribution, and unstable activity. The drying process can effectively remove moisture, allowing the coagulant to form a uniform solid film on the tube wall, ensuring its chemical activity is stable, and improving the efficiency and reliability of serum separation results. Strict process control is the fundamental guarantee for quality inspection.

Is the abnormality of triglycerides related to the addition of coagulants?

Is the abnormality of triglycerides related to the addition of coagulants?

Scientific analysis shows that there is no direct correlation between coagulant and abnormal triglyceride detection. Its mechanism of action is independent of lipid metabolism and does not interfere with detection. The key to ensuring accurate results lies in standardizing centrifugation operations, ensuring the cleanliness of blood collection tubes, and strictly controlling the quality of coagulants. A systematic specimen processing workflow is the core of improving detection reliability.

HEPES buffer: An indispensable guardian in oocyte washing

HEPES buffer: An indispensable guardian in oocyte washing

In nuclear transfer technology, the washing of fresh oocytes is a critical step, and its microenvironment stability directly affects the success or failure of the experiment. HEPES buffer is crucial in this process, as it can quickly respond and neutralize acidic substances produced by cellular metabolism, stabilizing the pH of the washing solution within the physiological range of 7.2-7.4, providing a guarantee for simulating in vivo homeostasis and maintaining normal activity of oocytes, thereby significantly improving the subsequent embryonic development rate. The high-purity HEPES products provided by Hubei Xindesheng provide reliable raw material support for such cutting-edge research.
