Ethylene Di-Amine Tetra Acetic Acid 3 In hematology, EDTA is the most commonly used anticoagulant for the complete blood cell count (CBC) or any of its component tests: hemoglobin, packed cell volume, total leukocyte count and leukocyte differential count, and platelet count.

This is theoretically the best anticoagulant because it is a normal blood component and does not introduce any foreign contaminants to the blood specimen Anticoagulants, commonly known as blood thinners, are chemical substances that prevent or reduce coagulation of blood, prolonging the clotting time. Some of them occur naturally in blood-eating animals such as leeches and mosquitoes, where they help keep the bite area unclotted long enough for the animal to obtain some blood.

The tissue supplied by a blocked artery becomes damaged or. concentrations of anticoagulants used in venous blood samples were defined in the international standard (86) in 1996.

The blood thinner has a narrow therapeutic index; requires frequent, consistent monitoring to prevent over- and under-dosing; has more than 200 drug-drug and drug-food interactions; and its use is restricted during pregnancy due to teratogenic effects NSAIDs are used to treat mild-to-moderate pain that arises from a wide range of conditions such as headaches, menstruation, migraines, osteoarthritis or rheumatoid arthritis, sprains and strains, and toothache.
