What color tube is used for a CBC?
LAVENDER
The following tests may be drawn in the same LAVENDER (PURPLE) top tube: CBC, SED RATE (ESR), RETICULOCYTE Draw an extra LAVENDER for each (GLYCOHEMOGLOBIN and BNP). 9. GLUCOSE is always drawn in a GRAY top tube. No additional test may be drawn with this tube.
What is a rainbow lab draw?
Clinical laboratories often receive extra blood tubes beyond what is needed for associated laboratory test orders. Sometimes, this practice involves drawing tubes of every possible color (the “rainbow”) to allow for add-on testing at a later time.
What tubes do you use for a CBC and CMP?
Container. Gel-barrier tube is preferred (send entire tube). Red-top tube or green-top (lithium heparin) tube is acceptable.
What tubes are in a rainbow draw?
The standard rainbow draw included 2 serum tubes [5.0 mL of rapid serum (RST) and 8.5 mL of serum separator (SST)], 4.0 mL of EDTA whole blood for hematology, 2.7 mL of sodium citrate plasma for coagulation studies, and 4.0 mL of fluoride/oxalate plasma for lactate, for a total of 24.2 mL of blood per collection.
What order do you draw lab tubes?
The draw order for specimen tubes is as follows:
- Blood culture.
- Blue tube for coagulation (Sodium Citrate)
- Red No Gel.
- Gold SST (Plain tube w/gel and clot activator additive)
- Green and Dark Green (Heparin, with and without gel)
- Lavender (EDTA)
- Pink – Blood Bank (EDTA)
- Gray (Oxalate/Fluoride)
What is the Green-Top blood Tube for?
Light green-top tube (lithium heparin) This tube contains lithium heparin and gel separator used for the collection of heparinized plasma for routine chemistry tests. NOTE: After the tube has been filled with blood, immediately invert the tube 8-10 times to mix and ensure adequate anticoagulation of the specimen.
What color tube is used for electrolyte testing?
Specimen Requirements Red-top tube or green-top (heparin) tube is acceptable if centrifuged within 45 minutes and the serum or plasma is removed and placed in a tightly-stoppered secondary tube.
