Red top tube SST- 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 off. Please contact the laboratory before taking the patient to obtain the correct tubes for metal analysis or another test, which are specified in the individual test lists.
What is the red test tube used for?
Remove the stopper and carefully suck all serum out of the cells, using a separate disposable pipette for each tube. With some needle assemblies, you can slide the collection tube into the holder while gently pushing the tubes forward until the needle touches the stopper. To allow adequate mixing, slowly turn the tube eight to ten times (four times for citrate tubes) with a gentle wrist twist. Blood collected with an anticoagulant suitable for the test described cannot be considered suitable for other tests.
When performed, it allows the technologist to microscopically view the actual appearance of red and white blood cells.
Is a red top tube an SST?
Attempts to push more blood into the tube by applying pressure, such as collecting with a syringe, resulting in red blood cell damage (hemolysis). These tubes should be used with caution when measuring drug or hormone levels as the drug or hormone may diffuse from the serum into the gel, which may result in a decrease in measured levels. If multiple tests are ordered, sufficient samples or quantities should be submitted to ensure the ideal recovery of organisms. Plasma preparation tubes (PPT) containing K2EDTA and gel for separation, spray-coated K2EDTA tubes are used for hematologic whole blood tests and immunohematology testing.
What color is an EDTA tube?
This is your basic hematology tube (which allows me to identify and count blood cells, blood type, etc..). But what if your protocol isn’t specified, or you want to adopt a method from another system, or you simply want to make sure that you save the best sample type for future analyses that have not yet been defined? Hopefully, I can help you find your way around all these different colored tubes. EDTA plasma This is the supernatant that is removed after centrifugation of the blood collected in a lavender top tube (purple). Plasma stored from EDTA-treated blood can also be used to measure most proteins, and genetic material can be easily stored from EDTA Buffy Coats (the interface between red blood cells and plasma after centrifugation, which contains white blood cells and platelets).
What do the different colored blood tubes mean?
If multiple samples are required, remove the first collection tube from its holder as soon as blood flow is interrupted, turn the first tube upside down to prevent clotting, and carefully insert the second tube into the holder. The filled tube is then removed, and another can be inserted and filled in the same way, aiding blood collection. In addition, the exact volume that should be taken from a particular vacutainer tube is shown on the label of each tube to minimize the errors that can occur if more or less blood is drawn into the tube, as each tube is an anticoagulant or additive or clot activator In some and the ratio of blood to the additive must be maintained to obtain the exact values of the tests. 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.
