Pink top tube for CBC- The chemical was chosen to preserve some characteristics of the sample and to work with the method used to perform the test. To make the vein more prominent, the patient may be asked to hold firmly onto a rubber ball, a thick bundle of gauze, etc. Most laboratory tests are performed using serum, anticoagulated plasma, or whole blood. 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.
The specified anticoagulant or preservative must be used for the ordered test.
Which blood tube is required to operate a CBC?
When frozen plasma is required, place the plastic transport tubes immediately in the freezer compartment of the refrigerator and tell your professional service agent that you have a frozen sample to collect. A tiny rubber cover automatically closes when the vacuum tube is removed from its holder, preventing leakage and blood loss when changing tubes. If there are any doubts or questions about the type of sample to be taken, it is imperative to call the laboratory to clarify the sequence and sample requirements.

If a Coag tube (light blue) is the only or first tube to be drawn, a 5 ml disposal tube must be drawn first.
Can I use the pink top tube for CBC?
Rapid Serum Tubes contain a proprietary thrombin-based medical coagulant and a polymer gel for serum separation. In quantitative blood cultures, blood must be drawn from the same location into an SPS tube in addition to the aerobic and anaerobic bottles. This tube should not be used for drug analysis as some drugs can bind to the gel and give incorrect results. This tube must be completely filled; the ratio of blood to anticoagulant is crucial for valid coagulation results.
Immediately after filling, shake the tubes ten times (just hard enough) to ensure that the entire inner surface of the tube is covered with blood.
