These tubes contain a high-purity grade of EDTA, which acts as an anticoagulant by preventing the blood sample from clotting. EDTA tubes are widely used in hematology procedures, including complete blood count (CBC), full blood examination (FBE), EDTA plasma preparation, whole blood collection, bone marrow specimen collection, HPLC, HbA1c testing, blood grouping, and PCR testing for dengue and chikungunya. They are also commonly used in research and diagnostic investigations involving red cell grouping, antibody screening, Rh typing, HIV RNA detection, red cell folate analysis, blood film examination, reticulocyte counts, and various other hematological tests.
