Blood Collection Tube Additives EDTA K3 65501-24-8 Tripotassium Salts High Purity

The collection and processing of blood samples is a crucial task in medical diagnosis and laboratory research. Purple EDTA dipotassium blood collection tube is a common blood collection tool. The EDTA dipotassium it contains is an anticoagulant used to prevent blood clotting and maintain the liquid state of blood samples. However, proper and gentle handling after blood collection is key to ensuring the quality of the blood sample. Next, 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.

Structure and function of purple EDTA dipotassium blood collection tube

The purple EDTA dipotassium blood collection tube usually consists of a blood collection needle, a tube with an anticoagulant EDTA dipotassium coating 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 tubes in medical practice. EDTA dipotassium is a chelating agent that can bind to calcium ions in the blood, preventing the activation of coagulation factors and achieving anticoagulant effects. This anticoagulant vessel is widely used in laboratory research and clinical testing in fields such as hematology, biochemistry, immunology, etc.

Possible problems caused by shaking forcefully

After blood collection, excessive shaking may damage this layered structure, causing blood cell rupture and triggering hemolysis. Hemolysis can release intracellular components, affecting the accuracy of blood analysis, especially for some sensitive biochemical indicators.

Causes of hemolysis phenomenon

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

The impact of hemolysis on experimental results

Hemolysis can have a significant impact on experimental results, mainly manifested 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. Cell count distortion: Hemolysis can lead to a decrease in the number of red blood cells, thereby affecting the red blood cell count results in blood routine tests.

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 advisable to avoid vigorously shaking the blood vessels. Instead, gently shake or flip the blood vessels to allow the anticoagulant to mix evenly with the blood without damaging the integrity of blood cells.

2. Follow operating procedures: Medical personnel should follow corresponding operating procedures when collecting blood to ensure a smooth blood collection process, including selecting the correct test tube and positioning the blood collection location appropriately.

When using purple EDTA dipotassium blood collection tubes, sufficient attention should be paid to the potential hemolysis caused by shaking vigorously. Proper blood sample processing is the basis for ensuring the accuracy of experimental results. Medical personnel and laboratory workers should always pay attention to operating procedures and take appropriate measures to avoid hemolysis.
