EDTA vials as anticoagulants play an essential role in clinical testing. Their excellent anticoagulant properties ensure that blood samples remain stable during collection, transportation, and testing, thereby guaranteeing the accuracy and reliability of test results. This article will explore in-depth the application of EDTA as an anticoagulant in blood collection tubes in clinical testing and its related precautions, providing strong support for medical testing.
EDTA prevents blood coagulation by forming stable chelates with calcium ions in the aqueous phase. Its salts, including potassium, sodium, and lithium, are all water-soluble, with potassium salt commonly used for whole blood cell counting due to its higher solubility. EDTA Vial Anticoagulants are not only efficient but also do not interfere with other components in the blood sample, ensuring the accuracy of test results.
Routine blood tests are fundamental methods for assessing a patient's health condition. EDTA Vials can effectively prevent blood samples from clotting during collection and transportation, maintaining the sample's stability and providing strong assurance for the accuracy of routine blood tests. Routine blood tests mainly include analysis of indicators such as white blood cells, hemoglobin, and platelets, with white blood cells further categorized into eosinophils, neutrophils, lymphocytes, monocytes, etc. Through routine blood tests, doctors can understand the patient's blood condition, providing important evidence for disease diagnosis.
Blood typing is crucial for determining an individual's blood type and is of significant importance in medical procedures such as blood transfusions and organ transplants. EDTA Vials can maintain the stability and anticoagulant effect of blood samples, ensuring the accuracy and reliability of blood typing tests. Through blood typing tests, doctors can understand the patient's blood type information, providing safety assurance for clinical treatment.
ABO hemolysis is a common immune reaction caused by blood type incompatibility, which can lead to severe clinical consequences. EDTA Vials play an important role in ABO hemolysis testing. By testing the antibody titer and other relevant indicators in the blood sample, the risk of ABO hemolysis in patients can be assessed, providing important evidence for prevention and treatment.
When using EDTA Vials, the following points should be noted: first, ensure good sealing of the blood collection tube to avoid leakage and contamination of the blood sample; second, operate according to the concentration recommended by ICSH to avoid the impact of excessively high or low anticoagulant concentration on test results; additionally, promptly prepare smears to reduce changes in granulocyte morphology; finally, for some special patients or specific testing items, other types of anticoagulants may need to be chosen based on the particular situation.
