肝素钠/肝素锂（Sodium Heparin/Lithium Heparin）

绿色安全头盖指示此类采血管中添加了以钠盐或锂盐型式存在的肝素抗凝剂。先进的微喷雾技术确保肝素抗凝剂迅速作用于血液标本 , 为临床实验提供立等可取的血浆标本 , 因而多用作急诊生化实验 , 同时 , 因肝素抗凝标本的血液流变学性质差别不大 , 故又常用于血液流变学实验。 Green cap indicate that there is heparin anticoagulant of sodium or lithium salt; with advanced micro atomizing technology to ensure heparin anticoagulant quickly acting in blood specimen, which provide clinical laboratory with immediate plasma specimen, therefore it is always used in emergency biochemical laboratory. In the meanwhile,due to small difference in the hem rheological changes nature of anticoagulant of heparin specimen, it is often used in hem rheological laboratory.
