Any material placed in a tube that maintains or facilitates the integrity and function of the sample.
Capillary Action
Adhesive molecular forces between liquid and solid materials that draw liquid into a narrow-bore capillary tube.
Fibrin Degradation Products (FDP's)
Fragments of the fibrin/clot found in the bloodstream.
Process at the end of the clotting process that breaks down fibrin into small fragments, called FDP's that lead to disintegration of the clot.
Metal Rod used for mixing the blood sample that fits inside the capillary tube.
Concentrating the constituents of blood by leaving the tourniquet on too long.
Process of formation of a blood clot when an injury occurs and then lysing of that blood clot when the injury has been repaired.
To search for a vein with a pressure-and-release touch.
Platelet Adhesion
The process of platelet clumps adhering to an injured area to stop bleeding.
Platelet Aggregation
The process of platelets clumping together during hemostasis.
Thixotropic Separator Gel
A gel material capable of forming an interface between the cells and fluid portion of the blood as a result of centrifugation.
Any constrictor used to facilitate vein prominence. approx 1 inch wide by 15 to 18in long. Applied 3-4 inches above puncture site.
Constriction of vessel(s) that limit blood flow.
Degree of thickness or resistance to flow of a substance.
Metric System Prefixes
Metric Conversion Chart
units in CC = mL
98.6¤ F = 37¤ C
Important Metric Conversions
1 kg= 2.2046 lbs
1 lb= .454 kg
0¤C= 32¤F (Freezing point of water)
100¤C= 212¤F (Water boils)
37¤C= 98.6¤F (Normal body temp)
Breathing a Syringe
Pull back on the plunger halfway up the barrel and then push the plunger back to allow the plunger to move more slowly and without the tendency to jerk when first pulled during a blood draw.

Activated Partial Thromboplastin Time (aPTT) Test
Measurement for the intrinsic pathway. Also used to monitor heparin therapy of an individual.
Prothrombin Time (PT) Test
Measurement for the extrinsic pathway. Also used to monitor warfarin therapy.
Intrinsic Pathway
List of factors within the coagulation cascade involving trauma within the vascular system. Factor XII, Factor XI (Calcium), Factor IX (Platelet Factor 3), Factor VIII
Extrinsic Pathway
List of factors within the coagulation cascade involving external trauma-tissue injury. Tissue Thromboplastin (Calcium), Factor VII
A condition where a person lacks the necessary coagulation factors for proper clotting of bleeding injuries.
