Color test tube- All samples prepared for transportation to the University of Washington Medical Center or Harborview Medical Center must follow these general instructions. An SST tube should never be replaced as the gel barrier may interfere with the analysis. After dabbing the area to be tested, place the swab back into the plastic case or insert the swab deep into the transport medium and break off the applicator just below where it was held or the scratched mark on the swab shaft. 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.
Which blood tube colors are there for which test?
If a Coag tube (light blue) is the only or first tube to be drawn, a 5 ml disposal tube must be drawn first.
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).
