Blood collection tubes play a pivotal role in the realm of medical and scientific research, facilitating the collection of blood samples for various tests and analyses. These tubes come in diverse types, each tailored for specific applications, ensuring the accuracy and reliability of test results. In this comprehensive overview, we delve into the various types of blood collection tubes, their unique features, and the critical distinctions that guide their usage.
Blood collection tubes are a fundamental component of the vacutainer system, which includes a needle, holder, and tube. This system is extensively utilized in drawing blood from patients for a myriad of tests, ranging from routine blood counts to sophisticated genetic analyses. Understanding the different types of blood collection tubes is essential for healthcare professionals, researchers, and laboratory technicians to ensure precise and valid outcomes in diagnostic procedures and medical research.
It is used in biochemistry, immunology, serology, detection of various viruses, detection of trace elements, blood bank detection、collection and storage of blood samples for medical examination.
Without any additive, the serum sample was obtained by centrifugation after sample solidification, and the normal composition of the serum could be maintained for a long time, it is beneficial to serum reexamination and has good repeatability.
It is used in collection and preservation of blood samples for biochemical and immunological tests in medical examinations.
The coagulant is evenly dispersed in the inner wall of the tube to completely coagulate the blood in a short time, and high-quality serum is obtained through centrifugation to avoid the problems caused by the coagulation rupture of blood cells, hemolysis and coagulation, to meet the rapid emergency serum biochemical experiments.
It is used in collection and storage of blood samples for biochemical, immunological and drug testing.
The coagulant was evenly dispersed in the inner wall of the tube, and the inert separation glue was located at the bottom of the collection tube. After blood samples were collected and centrifuged, the serum and blood cells formed a barrier, and high-quality serum was obtained. The serum was kept stable for more than 48 hours, and its biochemical properties and chemical composition did not change significantly.
It is used for the collection and preservation of blood samples such as medical blood routine examination and whole blood experiment, cross blood and blood type identification.
The EDTA salt is evenly dispersed in the tube wall and thoroughly mixed with the blood specimen. EDTA salt has the effect of protecting cell morphology, preventing the occurrence of clotting so that its shape and volume are not affected for a long time. Suitable for all kinds of blood cell analyzer.
It is used for the collection and preservation of blood samples for medical examination of plasma, emergency biochemistry and hemorheology.
The blood tube wall is evenly dispersed with heparin sodium or heparin lithium, which can quickly act on the blood sample and quickly obtain high-quality plasma. It is also suitable for the detection of trace elements, and has no effect on sodium ions. Plasma separation glue can be added according to customer requirements to prepare excellent plasma to meet the needs of clinical experiments.
It is used for the collection and preservation of blood samples for medical testing of all routine coagulation tests.
The tube contains 3.2% (0.109M) sodium citrate solution for anticoagulation, and the ratio of blood samples to anticoagulants is 9:1. Sufficient blood volume must be collected during blood collection to ensure the accuracy of test results.
It is used for the collection and preservation of blood samples for medical tests such as blood glucose, glucose tolerance, erythrocyte electrophoresis, anti-alkali hemoglobin, glyolysis and lactate.
Sodium fluoride and EDTAK2 are added into the tube, and sodium fluoride has the effect of inhibiting red blood cell glycolysis blood sugar. The combination of sodium fluoride and EDTAK2 can greatly reduce the hemolysis phenomenon, ensuring that the blood glucose detection data is constant within 72 hours.
It is used for the determination of blood sedimentation rate in medical examination. The 13*75mm tube is specially used for the collection and anticoagulation of blood samples during the detection of Weil ESR method, and the 8*120mm tube is used for the automatic ESR instrument.
Due to the small amount of blood collection, the negative pressure in the tube is small, and the blood drawing time is relatively longer, you should wait patiently until the blood stops flowing into the blood collection tube and thoroughly reverse and mix 5-8 times at 180℃, so that the anticoagulant and blood are fully mixed. Improper mixing can cause hemolysis, clotting or blood blisters, affecting the test results.
In conclusion, the diverse types of blood collection tubes cater to the intricate needs of medical and scientific investigations. The careful selection of the appropriate tube ensures the preservation of specimen integrity and the accuracy of test results. Researchers, healthcare professionals, and laboratory personnel must stay informed about the specific features and applications of each blood collection tube to enhance the efficacy of diagnostic procedures and advance medical knowledge.
