EDTA Glass Tube
An EDTA ( Ethylenediaminetetraacetic acid) glass tube is a specialized type of blood collection tube designed for the preservation of blood samples. EDTA is an anticoagulant, meaning it prevents blood from clotting by binding to calcium ions essential for the coagulation process. The use of EDTA tubes is common in various medical and laboratory settings for tests that require whole blood samples without clot formation.
Tube Composition: The EDTA glass tube is typically made of transparent or translucent borosilicate glass, allowing easy visual inspection of the collected blood sample. The tube is designed to withstand the rigors of transportation and processing within a laboratory environment.
Color-coded Stopper: The tube is sealed with a color-coded rubber stopper, indicating the type of anticoagulant used (in this case, EDTA). The color coding helps healthcare professionals and laboratory technicians quickly identify the type of tube and its specific use.
Anticoagulant Properties: The interior of the tube contains a measured amount of EDTA solution. EDTA binds to calcium ions, preventing the coagulation cascade and preserving the blood in a liquid state. This ensures that the blood sample remains in its original state for various hematological and biochemical analyses.
Application: EDTA glass tubes are commonly used for a range of tests, including complete blood counts (CBC), blood typing, DNA analysis, and various hematology studies. The preservation of the blood in a liquid state makes it suitable for automated analyzers and facilitates accurate and reliable test results.
Collection Procedure: During blood collection, a healthcare professional typically uses a sterile needle to draw blood directly into the EDTA glass tube. The tube is then inverted several times to ensure proper mixing of the anticoagulant with the blood, preventing clot formation.
Handling and Storage: Once the blood sample is collected, the EDTA tube should be handled with care to avoid breakage. Proper labeling with patient information is essential for accurate identification. The tubes are usually stored at room temperature until they are processed within a specified time frame to maintain the integrity of the blood sample.
In summary, an EDTA glass tube is a specialized tool designed for the anticoagulation and preservation of blood samples, making it a crucial component in various laboratory analyses within the field of clinical diagnostics and medical research to know more visit website..www.labmate.com
