Shake the purple EDTA dipotassium blood collection tube vigorously

Release time:


The collection and processing of blood samples is a crucial task in medical diagnosis and laboratory research. Purple EDTA dipotassium blood collection vessel is a common blood collection tool. It contains EDTA dipotassium, which is an anticoagulant used to prevent blood clotting and maintain the liquid state of blood samples. However, reasonable and gentle handling after blood collection is the key to ensuring the quality of blood samples. Below, we will talk about the possible problems caused by vigorously shaking the purple EDTA dipotassium blood collection tube, especially hemolysis, and how to properly handle blood samples to avoid this problem.

The structure and function of purple EDTA dipotassium blood collection vessels


The purple EDTA dipotassium blood collection vessel is usually composed of a blood collection needle, a tube with anticoagulant EDTA dipotassium coated on the tube wall, a short tube, and a short connector. The purple cap is designed to facilitate the identification of different types of blood collection vessels in medical practice. EDTA dipotassium is a chelating agent that can bind with calcium ions in the blood, preventing the activation of coagulation factors and achieving anticoagulant effects. This type of anticoagulant blood vessel is widely used in laboratory research and clinical testing in fields such as hematology, biochemistry, and immunology.


Possible problems caused by forceful shaking


After blood collection, excessive shaking with force may damage this layered structure, leading to the rupture of blood cells and causing hemolysis. Hemolysis can release intracellular components, affecting the accuracy of blood analysis, especially for sensitive biochemical indicators.


The causes of hemolysis


Hemolysis refers to the process in which red blood cells rupture under certain conditions, leading to the release of hemoglobin from within the cell to outside the cell. The main reason why shaking the purple EDTA dipotassium blood collection tube vigorously may cause hemolysis is that it can cause strong impact on red blood cells inside the tube, leading to the rupture of the red blood cell membrane and hemolysis.


The impact of hemolysis on experimental results


Hemolysis will have a significant impact on the experimental results, mainly reflected in the following aspects:


1. Hemoglobin interference: Hemoglobin released after hemolysis can interfere with the detection of many biochemical indicators, such as liver function, kidney function, and other indicators.


2. Distorted cell count: Hemolysis can lead to a decrease in the number of red blood cells, thereby affecting the red blood cell count results in blood routine testing.


3. Coagulation function testing is affected: Hemoglobin and other cellular contents released after hemolysis may interfere with the results of coagulation function testing, leading to misjudgment.


How to handle blood samples correctly


1. Gently Shake: When processing blood samples, it is important to avoid vigorously shaking the blood vessels. Instead, gently shake or flip the vessels to mix the anticoagulant evenly with the blood without damaging the integrity of the blood cells.


2. Follow operating procedures: Medical personnel should follow the corresponding operating procedures when collecting blood to ensure the smooth progress of the blood collection process, including selecting test tubes correctly and positioning the blood collection position appropriately.


Product packaging


When using purple EDTA dipotassium blood collection vessels, sufficient attention should be paid to the hemolysis issues that may occur due to vigorous shaking. The correct handling of blood samples is the basis for ensuring the accuracy of experimental results. Medical personnel and laboratory workers should always pay attention to operating standards and take appropriate measures to avoid the occurrence of hemolysis.
