The global light blue tube phlebotomy market is expected to swell at a considerable rate in the near future.

Some of them are Partial Thromboplastin Time (PTT), Fibrin degradation products (FDP), Thrombin Time (TT), Prothrombin Time (PT), Fibrinogen, and D-dimer. Various tests are performed using the light blue phlebotomy tube. As the additive gives a whole blood sample that is plasma and red blood cells, the light blue phlebotomy tubes have buffered tri-sodium citrate solution as well. It binds the calcium present in the blood that is required for clotting. Phlebotomy tubes with light blue stoppers primarily contain two additives: sodium citrate (3.2% or 3.8%) and Citrate, theophylline, adenosine, dipyridamole) or CTAD. Disorder related to clotting can result in thrombosis or hemorrhage. The course of action of coagulation includes activation, bonding, and accumulation of platelets in addition to deposition and development of fibrin. This process leads to hemostasis, and prevent the blood loss from the body. Blood clotting or coagulation is the method by which blood changes its form.

Phlebotomy is carried out for a range of reasons such as blood donations, medical testing, and research. Light blue top tubes are used for performing coagulation tests.

Medical laboratory scientists, doctors, and nurses often perform phlebotomy process as well. The procedure, also known as venipuncture, is primarily performed by specialists called phlebotomists. The process of drawing blood from veins is known as phlebotomy.
