What you need to know when using EDTA potassium salt

Release time:


Potassium EDTA has a wide range of uses. In addition to being used in vacuum blood collection tube additives, it can also be used in deodorants, complexing agents in liquid phase analysis, and metal polishing agents. Today, let's talk about some points that need to be known in the process of using EDTA potassium salt as a blood collection tube additive.

EDTA potassium salt blood collection tube

1. What inspection items are EDTA potassium salts suitable for?

EDTA potassium salt is a commonly used anticoagulant. After collecting blood samples, the blood collection tube with EDTA potassium salt added can protect the cell components of the blood, and does not affect the size and count of white blood cells, and has very little effect on the morphology of red blood cells. Can inhibit platelet aggregation. EDTA potassium salt is suitable for general hematology tests, but not suitable for platelet kinetic energy test and coagulation test. Assays for iron ion, alkaline phosphatase, creatine kinase, leucine aminopeptidase and PCR assay. 

2. What are the precautions for the use of EDTA potassium salt?

After blood collection through the EDTA potassium anticoagulation tube, the medical staff should gently reverse the blood collection tube 5-8 times as soon as possible. Too much force will cause the blood cells to rupture and cause hemolysis. blood clots. The EDTA anticoagulation tube should be tested within 24 hours after blood collection, otherwise the test results may be inaccurate. The anticoagulation tube needs an appropriate amount of EDTA potassium salt. Excessive amount may lead to changes in the morphology of blood cells. Insufficient amount will affect the anticoagulation effect. It is very important to control the amount of EDTA potassium salt added.

3. Frequency and result judgment of EDTA potassium salt sampling inspection?

Nowadays, EDTA potassium salts are produced in batches, and each batch of EDTA potassium salt products should be sampled at least twice under the same conditions to ensure the accuracy and consistency of the results. If the results of the two sampling tests are consistent, the result is determined to be valid, otherwise it is invalid, and if it is invalid, it needs to be re-tested until the results of the two sampling tests are consistent under the same test conditions. If any of the indicators in the valid results fail to meet the specified requirements, the result will determine that the product is unqualified and is not allowed to leave the factory.
