Gold top tubes- 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. Red Top Tube can ONLY be used for serum transport tubes. If a CBC is the only test ordered, please pull out a gold tube and throw away the gold tube. 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.
If a Coag tube (light blue) is the only or first tube to be pulled out, a 5 ml disposal tube must first be pulled become.
Which color tube is used for the CBC test?
The aseptic method for collecting and transporting blood samples uses the principle of a vacuum tube for blood collection. When more than one blood sample is required, multiple sample needles and vacuum tubes make blood collection easier and more efficient. The serum can be sent into the centrifuge tube with an intact barrier (correct separation during centrifugation) between cells and serum or in a plastic transport tube. Remove the stopper and gently aspirate the plasma using a separate disposable Pasteur pipette for each tube.
Hemolysis can be caused by rough handling of a blood sample, by allowing the tourniquet to run too long (causing blood congestion), or by squeezing the fingertip too much during capillary collection, dilution, exposure to contaminants, extreme temperatures, or pathological conditions.
What is the gold tube used for during phlebotomy?
This is your basic hematology tube (by which I mean identifying and counting blood cells, blood type, etc.) If you only need samples collected in citrate blood collection tubes for your project, you should remove a disposal tube first. It is worth noting that a citrate tube should not be the first type of tube to be filled after the venipuncture – the first few ml of the drawn blood are slightly activated. There are more blood collection tubes for more specific purposes, but hopefully, this will give you an overview of where to start.
Which tube is used for CBC and CMP?
In general, liver function panels or liver function tests (LFTS) and a comprehensive metabolic panel (CMP) containing LFTs are usually drawn in a light green tube. However, some labs may have variations of this color scheme. So I’d check with your lab to determine the exact color they’re using.
