EDTA K3

K3 EDTA (Tripotassium EDTA) Blood Collection Tubes are anticoagulant specimen tubes designed primarily for the collection of whole blood for hematology testing. K3 EDTA binds calcium ions in the blood, thereby preventing the coagulation cascade and keeping the specimen anticoagulated for laboratory analysis. They are commonly used for Complete Blood Count (CBC), hematology parameters and blood-cell morphology and are compatible with appropriate automated hematology analyzers. K3 EDTA tubes are available in different draw volumes and configurations, including vacuum and non-vacuum versions. Purple/violet closures are commonly used for EDTA tubes, although exact closure colors can vary by manufacturer and regional standards.
