Question | Answer |
---|---|
ANTICOAGULANTS (common) | EDTA; Citrate (sodium); Heparin (ammonium, lithium, sodium); Oxalates (potassium) |
SPECIAL USE ANTICOAGULANTS | Acid Citrate Dextrose (ACD); Citrate-Phosphate-Dextrose (CPD); Sodium Polyanethol Sulfonate (SPS) |
ANTI-GLYCOLYTIC AGENTS | Sodium Fluoride |
CLOT ACTIVATORS | Silica (glass); Celite (inert clay); Thrombin; SSTs = Serum separator tubes |
THIXOTROPIC GEL SEPARATOR | density of gel is between that of cells and serum or plasma |
TRACE-ELEMENT-FREE TUBES | tubes are made from materials that are as free of trace element contamination as possible; they typically contain EDTA, heparin, or no additive |
LIGHT BLUE | ADDITIVE=Sodium Citrate//DEPT.=Coagulation |
RED GLASS | ADDITIVE=none//DEPT.=Chemistry, Blood Bank, Serology, Immunology |
RED PLASTIC | ADDITIVE=clot activator//DEPT.=Chemistry |
RED/LIGHT GRAY PLASTIC | ADDITIVE=nonadditive//DEPT.=NA(discard tube only) |
RED/BLACK(tiger) or GOLD or RED/GOLD | ADDITIVE=clot activator & gel separator//DEPT.=Chemistry |

PT/PTT | prothrombin time/partial thromboplastin time INVERT 5-8 times-> must draw discard tube if this is first tube drawn!! |
To get serum, use: | Plain Tubes or Clot Activators (CAT) |
To get plasma, use: | Anticoagulants |
BLOOD CULTURES | Yellow SPS, sterile media bottles |
COAGULATION STUDIES | Light Blue, |
SERUM STUDIES | Gold, Red Glass, Red Plastic |
PLASMA STUDIES | HEPARIN -> green,light green,tan glass//EDTA->lavender,pink,royal blue,pearl, tan plastic//O&F->Gray |
LAVENDER TUBE | Used for CBC |
