BD Vacutainer citrate tubes are specialized blood collection tubes designed for the collection of blood samples for coagulation testing, specifically for tests that require citrate as an anticoagulant. These tubes are commonly used for tests such as prothrombin time (PT), activated partial thromboplastin time (APTT), and other clotting factor assays. The Vacutainer citrate tubes contain a fixed concentration of sodium citrate, which acts as an anticoagulant by binding to calcium ions, thereby inhibiting the clotting process. The tubes are made from high-quality plastic and feature a vacuum-sealed system for safe and efficient blood collection. The ratio of citrate to blood is precisely calibrated to ensure accurate test results. Our BD Vacutainer citrate tubes provide a standardized and reliable solution for coagulation testing, ensuring the preservation of sample integrity and accurate laboratory analysis.
