- Back
|
A.C.D. |
-Acid Citrate Dextrose -acid citrate=anticoagulant, binds calcium, preserves cells+platelets -dextrose feeds RBCs -Solution A+B -Used in DNA testing, human leukocyte phenotyping (HLA)+transplant compatibility -YELLOW top (not gold) -processed in Blood Bank OR Immunohematology |
|
|
Antiglycolytic agent |
-Substance that prevents the breakdownour metabolism of glucose by blood cells -sodium flouride=most common |
|
|
Antiseptic |
-substance used to prevent sepsis, which is the presence of microorganisms or their toxic substances in the bloodstream -greek "anti"=against + "septikos"=putrefactive -examples=70% ethyl/isopropyl alcohol, hydrogen peroxide, povidone-iodine, chlorohexadine gluconate, bensalkonium chloride |
|
|
Disinfectant |
-regulated by the EPA and used to remove or kill microorganisms on surfaces and instruments -not safe for contact with human skin -does not kill bacterial spores, so reusable equipment must be sterilized |
|
|
EDTA |
-ethyline diamine tetraacetic (all one word) acid -anticolagulant -makes calcium ions unavailable for coagulation -preserves cell shape+structure (morphology) better than any other anticoagulant -lavender, pink, white/pearl top tubes -salt spray preferred over liquid bc of dilution |
|
|
ETA |
-evacuated tube system -multisample needle+tube holder/hub+evacuated tubes |
|
|
Heparin |
-anticoagulant -kelly green or mint green tube tops (also mottled green+grey tops, microhematacrit with red or green bands) -inhibits thrombin (which converts fibrinigen into fibrin and factor X) -ammonium, lithium or sodium formulations -lithium most common bc of least interferance with chemistry test -don't use lithium for testing lithium levels or sodium for sodium or electrolyte panels |
|
|
Potassium oxalate |
-anticoagulant that binds and removes calcium in insoluble salt -commonly used with a glucose preservative (such as sodium flouride) -grey top tubes (8-10 inversions) |
|
|
PST |
-Plasma separater tube -thixotropic gel and heparin - STAT tests -mint green top |
|
|
RST |
-Rapid Serum tube -orange or gray/yellow tube top -contains thrombin additive for clotting within 5 minutes -processed by chemistry dept. |
|
|
Sodium citrate |
-anticoagulant by binding or chelating calcium -does the best job of preserving the coagulation factors -light blue tube tops processed in coagulation dept. (3-4 inversions) |
|
|
Sodium flouride |
-antiglycolytic agent -also inhibits growth of bacteria -must be used with an anticoagulant for plasma samples or it will clot blood (can be used alone for serum specimens) -grey top tube (5-10 inversions) |
|
|
SPS |
-sodium polyanethol sulfonate -anticoagulant that binds calcium -used in blood culture, bc it reduces action of complement protein that destroys bacteria -slows down phagocytosis (leukocytes ingesting bacteria) -inhibits some antibiotics -yellow (not gold) top tube drawn first (8 inversions) processed in microbiology |
|
|
SST |
-serum separator tube -gold or red/black tiger top tube with thixotropic gel and silica -5 inversions processed in chemistry |
|
|
Thixotropic gel |
-inert synthetic gel that changes viscosity when centrifuged and separates the plasma or serum from the blood cells -prevents cells from metabolizing substances in serum/plasma |
|
|
PPT |
-plasma preparation tubes -white/pearl tops with EDTA additive -used for molecular diagnostic tests (like pcr) |
