Additional Information for Laboratory Coagulation Tube
Laboratory Coagulation Tubes are a type of specialized tube used in medical and laboratory settings to collect and analyze blood samples for coagulation studies. These tubes are specifically designed to facilitate the process of blood clotting and to prevent the sample from clotting prematurely.
Coagulation tubes are typically made of transparent plastic or glass and come in various sizes, ranging from 1.8 mL to 5 mL. They are color-coded with a light blue or blue top to indicate their specific purpose for coagulation testing.
The tubes contain a specific additive called sodium citrate, which acts as an anticoagulant by binding to calcium ions in the blood, thereby preventing clot formation. The most common concentration of sodium citrate used in coagulation tubes is 3.2% or 3.8%.
When collecting a blood sample using a coagulation tube, the tube is filled to a specific level to maintain the correct ratio of blood to anticoagulant. The recommended blood-to-additive ratio is typically 9:1 or 4.5:1, depending on the specific test being performed.
Once the blood sample is collected, the tube is gently inverted several times to ensure proper mixing of the blood with the anticoagulant. The sample is then sent to the laboratory for further analysis, where it is centrifuged to separate the plasma from the cellular components of the blood.
Laboratory Coagulation Tubes are an essential component in coagulation testing, which is used to diagnose and monitor various bleeding disorders, clotting disorders, and to assess the effectiveness of anticoagulant therapy.
It is important to handle and store coagulation tubes properly to maintain the integrity of the blood sample and ensure accurate test results. These tubes should be stored upright at room temperature and protected from direct sunlight. It is also crucial to follow proper disposal procedures for used coagulation tubes, as they may contain potentially infectious materials.
Overall, Laboratory Coagulation Tubes are a vital tool in the field of laboratory medicine, enabling healthcare professionals to assess and monitor the coagulation status of patients for diagnostic and therapeutic purposes.
