From Wikipedia, the free encyclopedia
Vacutainer/sample tube types for venipuncture/phlebotomy   edit
Tube cap color or type in order of draw Additive Usage and comments
Blood culture bottle Sodium polyanethol sulfonate (anticoagulant) and growth media for microorganisms Usually drawn first for minimal risk of contamination.[1] Two bottles are typically collected in one blood draw; one for aerobic organisms and one for anaerobic organisms.[2]
Blue

("light blue")

Sodium citrate

(weak calcium chelator/anticoagulant)

Coagulation tests such as prothrombin time (PT) and partial thromboplastin time (PTT) and thrombin time (TT). Tube must be filled 100%.
Plain red No additive Serum: Total complement activity, cryoglobulins
Gold (sometimes red and grey "tiger top"[3]) Clot activator and serum separating gel[4] Serum-separating tube (SST): Tube inversions promote clotting. Most chemistry, endocrine and serology tests, including hepatitis and HIV.
Orange Clot activator and serum separating gel[5] Rapid serum-separating tube (RST).
Dark green Sodium heparin (anticoagulant) Chromosome testing, HLA typing, ammonia, lactate
Light green Lithium heparin (anticoagulant)

Plasma separator gel

Plasma. Tube inversions prevent clotting
Lavender ("purple") EDTA (chelator / anticoagulant) Whole blood: CBC, ESR, Coombs test, platelet antibodies, flow cytometry, blood levels of tacrolimus and cyclosporin
Pink K2 EDTA (chelator / anticoagulant) Blood typing and cross-matching, direct Coombs test, HIV viral load
Royal blue

("navy")

EDTA (chelator / anticoagulant) Trace elements, heavy metals, most drug levels, toxicology
Tan Sodium EDTA (chelator / anticoagulant) Lead
Gray

Fluoride Oxalate

Glucose, lactate,[7] toxicology[8]
Yellow Acid-citrate-dextrose A (anticoagulant) Tissue typing, DNA studies, HIV cultures
Pearlescent ("white") Separating gel and (K2)EDTA PCR for adenovirus, toxoplasma and HHV-6
Black Sodium Citrate Paediatric ESR
QuantiFERON

Grey, Green, Yellow, Purple

QuantiFERON

1. Grey (nil) tube 2. Green (TB1 antigen) tube 3. Yellow (TB2 antigen) tube 4. Purple (mitogen) tube

Tuberculosis
