QuantiFERON-TB Gold (QFT) comes in a set of four (tubes) and is used to detect Mycobacterium tuberculosis, the bacteria that cause tuberculosis (TB).

The tube is used to collect serum for selected chemical tests and specialized immunohematology tests.

What tests are Red Top Tubes used for?

Well-prepared films can be used to determine the differential white blood cell count, to study the morphology (size, structure and shape) of red and white cells to determine the presence of abnormal cells and to study the size and number of platelets. Since additives are not interchangeable, it is necessary to consult the sample requirements section of the individual test descriptions to determine the appropriate collection requirements for the ordered test. Red blood cells are sensitive, round, concave bodies that contain hemoglobin, the complex chemical that transports oxygen and carbon dioxide. Blood collected with an anticoagulant suitable for the test described cannot be considered suitable for other tests.

What is the red blood tube called?

A Vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper that creates a vacuum seal inside the tube and makes it easier to draw a predetermined volume of fluid. The aseptic method for collecting and transporting blood samples uses the principle of a vacuum tube for blood collection. Always use the correct vacuum tube for tests that require a specific anticoagulant (such as EDTA, heparin, sodium citrate, etc.) or preservative. A syringe is usually used for patients who are difficult to remove through routine venipuncture procedures, including techniques that use a safety wing blood collection kit (butterfly).

After experiencing a variety of shortages, crises, and inefficiencies in the status quo of the procurement and distribution industry, I undertook the responsibility of building an interface for large organizations to abstract away uncertainty throughout their supply chain under most conditions.

We are focused on building a framework from which our teams of professionals on the ground can provide a new generation of procurement support and professional services for supply chain critical organizations around the nation.

We understand that the marketing process of critical supplies is a matter of national security and public safety. In this, we found our passion and mission: developing technologies, supplier networks, and platforms for the organizations that need it most.
