Question | Answer |
ACD | Additive used for immunohematology tests such as DNA and HLA typing |
Additive | Substance added to a blood collection tube |
Anticoagulant | Substance that prevents blood from clotting |
Antiglycolytic agenct | Additive that prevents the breakdown of glucose by the cells |
Antiseptics | Substances used for skin cleaning that inhibit the growth of bacteria |
Bevel | Point of needle that is cut on a slant for ease of skin entry |
Butterfly needle | Winged infusion blood collection set |
Clot activator | Coagulation-enhancing substance, such as silica |
Disinfectant | Solutions used to kill microorganisms on surfaces and instruments |
EDTA | Anticoagulant that preserves cell shape and structure and inhibits platelet clumping |
ETS | Abbreviation for the collection system typically used for routine venipuncture |
Evacuated tube | Premeasured vaccum tube that is color-coded based on its additivie |
Gauge | Number that is related to the diameter of the needle lumen |
Glycolysis | Breakdown or metabolism of glucose by blood cells |
Heparin | Anticoagulant that inhibits the formation of thrombin |
Hub | End of the needle that attaches to the blood collection device |
Hypodermic Needle | Type of needle used when collecting blood with a syringe |
Lumen | Internal space of a vessel or tube |
Multisample needle | Type of needle used to collect several tubes during a single venipunture, beveled needle on each end that screws into the holder. One end beveled and short end has a sleeve that retracts as the needle goes through the tube stopper |
Order of draw | Special sequence in which tubes are filled during a mulitple-tube draw |
Potassium oxalate | Anticoagulant commonly used with an antiglycolytic agent |
PST | Heparinized gel tube for separation of cells and plasma |
Shaft | Long culindrical portioin of a needle |
Sharps conatiner | Special puncture-resistant leakproof disposable container |
Silica | Clot activator |
Sodium Citrate | Anticoagulant commonly used to preserve coagulation factors |
Sodium Flouride | most common antiglycolytic agent |
SPS | Additive used in blood culture collection |
SST | Gel tube for seperation of cells and serum |
Thixotropic gel | Synthetic substance used to separate cells from serum or plasma |
Winged infusion set | Butterfly needle |
Citrate, EDTA, Potassium oxalate | Binds calcium (anticoagulant) |
Most common skin antiseptic for routine blood collection | 70% isopropyl alcohol |
Results in Hemoconcentration | the tourniquet if left in place for more than 1 minute |
The smaller the gauge | The larger the diameter of the lumen |
Selection of evacuated tube depends on these factors | age of patient, amount of blood needed for the test and the size and condition of the patient's vein |
Short draw | underfilled tube |
Syringe transfer device | allows the safe transfer of blood into the tubes without using the syringe needle of removing the tube stopper |
Use this method of collection when the patient has small or difficult veins such as hand veins, veins for the elderly or pediatric patients | winged infusion set (butterfly) |
Lavendar tube contain | EDTA, 8-10 inversions, hematology tests |
Green tubes contain | Heparin, 5-10 inversions, chemistry tests |
gray tubes | Potassium oxalate & sodium flouride, 8-10 inversions, antiglycolytic tests |
Carry over | transfer of additive from one tube to the next |
prevent carry over and reflux by | filling tubes so the blood fills in the bottom of the tube first, blood should not touch the stopper during filling |
