(1) EDTA tube is widely used in clinical haematology as well as various kinds of blood cell test instruments. It offers a comprehensive protection for blood cell, .it can effectively stop the gathering of blood platelet and makes the form and volume of blood cell uninfluenced in a long time. (2) ESR tube is used for the detection of blood cell sedimentation rate test in clinical medical examination, the ratio of anticoagulant to blood collection is 1: 4. (3) glucose tube is used in blood specimen collection and anticoagulation for the analyses such as blood sugar, sugar tolerance, anti-alkali haemoglobin and sugar water.It can keep the original character of blood sample for a long time. (4)PT tube is mainly used for Sodium Citrate is mainly used for the test of PT,APTT, FIB,TT of blood coagulation mechanism in clinical medical examination. The ratia of anticoagulant to blood collection is 1:9. (5)heparin tube is used in blood collection and anti-coagulation not only for routine clinical biochemistry tests and emergency biochemistry tests but also forblood rheology test . (6) plain tubeis no additive tube. It is used in blood collection and storage for biochemistry, immunology and serology tests in medical inspection.The inner wall of the test tube is silicified to minimize the phenomenon of wall hanging (7) Clot Activator Tubeis usedto collect blood samples quickly in clinical medical examination such as biochemistry and immunity. As clot activator in the test tube. The coagulation time can be shortened and high quality serum can be obtained by centrifuge. (8) Gel&Clot Activator Tube is mainly used to obtain high quality serum samplesin biochemical, immune and other clinical medical tests. Separation gel is a semisolid inert gum. After blood collection and centrifugation, serum and plasma can be completely separated, thus ensuring the high quality of serum.
