It all depends on what system your using. If by tube you are referring to vaccutainers (blood sample containers) then you have to check. I know that purple top (EDTA) is for the ABC CBC machine as well as a manual blood smear since you need whole blood and EDTA minimizes any distortions.
Blood for CBC is usually collected in a purple-top tube (containing EDTA).
In most cases, a lavender top (EDTA) tube, with at least 4 ml's. Diff's can also be done on other tubes which have anti-coagulant additives, such as the citrate "Blue top" tube, if there is a specific need for a non-EDTA sample (for example; some rare patients platelets will clump in EDTA). This is not preferred however as blue tops are less forgiving on short draws, and rapidly lose accuracy if not completely filled (which is one of the reasons why they are second in priority after blood cultures). EDTA tubes can, if necessary, be partially filled and still give accurate results.
Lavender color tube containing the anticoagulant EDTA is ideal for CBC test.
Purple Tops are used for full blood counts (CBC test). EDTA is the abbreviation for ethylenediaminetetraacetic acid (you can see why it's abbreviated). The EDTA in purple top tubes is actually usually the potassium salt of this. It's used to keep the blood from coagulating.
CBC and ESR can be run off of a EDTA tube. CMP and VANC may require two separate tubes depending on hospital policy. CMP is usually run off of a green top (Lithium Heparin) tube and I'm not sure on the VANC tube.
EDTA test tube (Lavender top) for CBC etc. Heparinized test tube (Green top) for CD4 and absolute lymphocyte count Sodium floride(Grey top) for sugar test.
