Tubes for phlebotomy- While the number of colors may seem overwhelming for normal people, healthcare professionals are trained to draw blood and distinguish one test tube from another, as required by the sample being withdrawn. While the number of colors may seem overwhelming for normal people, healthcare professionals are trained to draw blood and distinguish one test tube from another, as required by the sample being withdrawn. Other tests that are not classified as anticoagulants or coagulants use different tubes that contain certain additives or no additives at all. Different phlebotomy tubes are identified based on the color of the stopper or shield.
The additives present in vacutainer tubes play the most important role, as each additive has a unique function, and these are selected according to the tests to be carried out.
What do the different colors of blood tubes mean?
A Vacutainer blood collection tube is a sterile glass or plastic tube with a seal that is evacuated to create a vacuum within the tube that makes it easier to draw off a predetermined volume of liquid. Vacutainer tubes work on the pressure difference that creates between the blood vessel and the vacuum in the tubes, which forces the blood through the needle into the tube. There is a standard protocol for the color code on blood collection tubes, which is universally used throughout the medical sector. It is not common to use it, and it contains silica particles as a clot activator to separate blood serum. It can be used in hormone tests and toxicological tests, but the yellow color has all the share of it, and it can be found in the form of a glass.
Which color tube would you use for the blood sample?
It can be a good, stable way to measure blood proteins, lipids, hormones, electrolytes, etc. To transport swab samples or tissue, remove the cap, place the sample in the tube (break off the swab handle if necessary) and put the cap back on and pull. The first thing to find out is whether you need to seek serum or whether you need to prevent blood clotting. Before collecting the patient, please contact the laboratory to obtain the correct tubes for metal analysis or other tests as specified in the individual test lists.
Plasma stored from EDTA-treated blood can also be used to measure most proteins, and genetic material can easily be stored from EDTA Buffy Coats (the interface between red blood cells and plasma after centrifugation, which contains white blood cells and platelets).
What does a purple blood tube mean?
There are numerous coagulation factors (factor VIII, factor IX, etc.) that are involved in blood coagulation. Blood collected with an anticoagulant suitable for the test described cannot be considered suitable for other tests. It works with the same purple tube mechanism but is more commonly used in blood transfusion analyses of blood samples as it also contains the anticoagulant EDTA and is used to examine the patient’s blood type and then compare it with other types to find the appropriate type for blood transfusion To find, or so-called cross-match, as far as the way it is used is concerned, it is similar to the first type in that you have to be constantly stirred to mix with the substance, an anticoagulant. The chemical was chosen to preserve some characteristics of the sample and to work with the method used to perform the test.
