Desheng EDTA tripotassium anticoagulant

Blood test is a very important and widely used test item at present, and almost all outpatients and inpatients have to undergo this test. In the past, blood tests were all manual tests, but now they have been developed into fully automatic instrument tests, which speeds up the waiting time during the test. Ethylenediaminetetraacetic acid dipotassium salt is an anticoagulant recommended by the International Committee for Standardization in Hematology (ICSH) for counting blood cell analyzers. It has the characteristics of good anticoagulation effect and relatively little influence on blood cell morphology, and can maintain red blood cells and white blood cells. And the platelet volume and shape will not change, and it has good stability.

Although, ethylenediaminetetraacetic acid dipotassium salt dihydrate (EDTA-2K) is considered to be the most ideal anticoagulant for complete blood count and classification, there are many things that need attention in its practical application.
First of all, regarding the selection of the concentration of EDTA-2K, vacuum blood collection tubes containing EDTA-2K anticoagulant are currently widely used. The blood collection during daily testing is usually 0.5-2ml, but we often find that hospitals or physical examination units actually The amount of blood collected is much larger than this range, which may cause a serious imbalance in the ratio of blood to EDTA-2K anticoagulant, resulting in clotting or slight clotting of blood samples, or even clogging of blood analyzer tubes or inaccurate analysis results. In particular, the false decrease in the number of platelets. If the blood volume is too low, the blood sample is diluted and the test result can be reduced.
In addition, at room temperature, it is tested on an automatic blood cell analyzer at different times after the blood is drawn. At room temperature, the blood cell count will not be affected within 24 hours, and the volume of blood cells will increase with time. Therefore, when analyzing the results of routine blood tests for EDTA-K2 anticoagulation and diagnosing diseases, the impact of the test time on the results should be considered.
Hubei Desheng Biotechnology has focused on the research and development and production of blood collection reagents for many years. At the beginning of its establishment, the company used anticoagulants as its core product. After more than ten years of research and development, it has now been sold to more than 100 countries around the world, and most of them have received favorable reviews for repurchase. The quality of our products is reliable, and the price can be discussed in detail. If you are interested, you can call for consultation. Desheng welcomes your calls.
