2024-03-03


EDTA-2K is a commonly used anticoagulant used for the collection and preservation of blood samples. It can bind with calcium ions in the blood, thereby preventing blood coagulation. In medical laboratories, the purple blood routine test tube of potassium ethylenediaminetetraacetate is a common blood collection vessel used for collecting and preserving blood samples. Below, we will provide a detailed introduction to the specifications and usage precautions of the purple blood routine test tube containing potassium ethylenediaminetetraacetate.

 

EDTA-2K powder

 

Potassium ethylenediaminetetraacetate test tubes typically contain the following specifications:

 

(1) Capacity: Generally 5 milliliters or 7 milliliters, sufficient to accommodate blood samples and tube caps.

(2) Color: The cap is purple, and the tube is transparent for observing blood samples under natural light.

(3) Tube cover: equipped with a tight cover to maintain the sealing of the blood sample.

(4) Material: Generally made of plastic or glass, it has good resistance to chemical corrosion and biocompatibility.

 

Precautions for use

 

When using a purple blood routine test tube containing potassium ethylenediaminetetraacetate, the following precautions should be taken:

 

1. Collection method: When collecting blood samples, ensure that the blood collection needle is tightly connected to prevent air from entering the test tube. At the same time, the blood collection needle should be inserted into the inside of the test tube to avoid other adverse effects.

 

2. Anticoagulant ratio: Potassium ethylenediaminetetraacetate is an anticoagulant that forms insoluble chelates with calcium ions in the blood, thereby preventing blood clotting. Therefore, when using test tubes, attention should be paid to the ratio of anticoagulants to blood to ensure the accuracy of blood samples.

 

3. Storage temperature: The collected blood samples should be stored at room temperature, avoiding direct sunlight and high temperature environments. If blood samples need to be stored at low temperatures, they should be placed in the refrigerator, but be careful not to come into contact with other items to avoid cross contamination.

 

4. Avoid shaking: After collecting blood samples, violent shaking should be avoided to prevent hemolysis or sample contamination. If you need to mix the blood sample evenly, you can gently invert the test tube.

 

5. Timely submission for testing: The collected blood samples should be sent for testing in a timely manner to avoid blood deterioration or contamination caused by prolonged time. Before sending for testing, ensure that the test tube is tightly sealed to maintain the integrity of the sample.

6. Special circumstances: For patients with certain special diseases or drug use, special attention should be paid when collecting blood samples using a purple blood routine test tube containing potassium ethylenediaminetetraacetate. For example, some diseases may affect the mechanism of blood coagulation, leading to the inability of blood to coagulate normally; Some drugs may interfere with the action of anticoagulants, leading to abnormalities in blood samples. Therefore, before collecting blood samples, it is necessary to understand the patient's disease history and medication situation, and take corresponding measures to avoid errors and safety hazards.

 

The purple blood routine test tube of potassium ethylenediaminetetraacetate, as a commonly used anticoagulant in blood collection additives, plays an important role in medical laboratories. During use, the operating procedures and safety regulations should be strictly followed, and attention should be paid to factors such as the ratio of anticoagulants and storage temperature.
