Phlebotomy is the process of drawing blood from a patient's veins for diagnostic or therapeutic purposes. The light blue tube phlebotomy, also known as coagulation testing, is a specialized procedure used to collect blood for coagulation studies. Coagulation is the process of blood clotting, which is essential for wound healing and preventing excessive bleeding. The light blue tube contains a sodium citrate additive, which acts as an anticoagulant and prevents blood clotting during transportation and testing.
The Light Blue Tube Phlebotomy is performed using a standard venipuncture technique. The phlebotomist will clean the patient's skin with an antiseptic solution and select the appropriate vein for blood collection. They will then insert a sterile needle into the vein and draw the blood into the light blue tube. The tube is gently inverted several times to ensure proper mixing of the anticoagulant with the blood. The needle is then removed, and pressure is applied to the puncture site to stop any bleeding. The tube is labeled with the patient's information and sent to the laboratory for testing.
