an allergic reaction to skin allergen contact
Ancillary blood glucose test
bedside dermal puncture to determine the blood glucose level

small needle with a flexible tube for delicate veins
capillary tube- microhematocrit tube
a small tube used for hematocrit tests
centrifuging
the act of separating components of a sample based on density by using a machine that spins a sample at a very high rate of speed ( the device is called centrifuge)
cephalic vein
a prominent vein the antecubital fossa, second choice for a blood draw
chemistry panel
a group of blood chemistry tests; the most common is chem 7
clot activators
additives that stimulate blood clotting
coagulation
clotting
complete blood count (CBC)
used to test for conditions that affect the number and ratio of cell types in the blood; most common blood test
contact precautions
used when a patient is well known or suspected to have a serious illness that may be spread by direct contact
differential (diff)
assesses the ratio of the different types of white blood cells (WBCS) and to look for changes in the RBC’s and platelets
differential count
determination of the proportions of the various blood cell types
droplet precautions
used for patients who are known or suspected to transmit serious illness by large-particle droplets (tuberculosis)
Flea

health insurance portability and Accountability Act (HIPPA)
patient privacy act
hematocrit (HCT)
determines the percentage of blood volume that is RBCS
Hematoma
a swollen, reddened area under the skin where blood collects
Hemoconcentration
increase in the ratio of formed elements in the plasma, usually caused by leaving the tourniquet on for too long
Hemoglobin (Hgb)
gives blood its red color because it contains iron; transports oxygen
Hemolysis
the destruction of RBCS
Hemostasis
the process by which the body stops blood from leaking out of a wound
Heparin or saline lock
a tube temporarily placed on the peripheral vein, may be used to administer medicine or draw blood
Joint Commission on Accreditation of Healthcare organizations (JCAHO)
monitors and evaluates the quality of patient care; the institution will lose medicare funding if it has not been accredited by JCAHO
Luer Adapter
used to attach a butterfly needle to an evacuation tube
Lumen
the hollow part of the needle
material safety data sheets (MSDS)
provides information on chemicals, their hazards and procedures for cleanup and first aid
Median Cubital vein
prominent vein in the antecubital fossa; the first choice for blood draw
micro collection tube - Bullet
small tube used to collect dermal puncture samples
micro pipette- caraway pipette or Natelson Pipette
large glass capillary tube
multi sample needle
a double-ended needle designated to be used with an evacuation tube system
needle adapter
translucent plastic cylinder connecting a multi-sample needle to an evacuated tube
occuluded
blocked
occupational safety and health administrations (OSHA)
regulates safety in the workplace
order of draw
prescribed sequence in which tubes with different additives should be filled during multi-tube collection
palpation
probing and feeling
Pathogen
infectious organism
Personal Protective equipment
gowns, masks, respirators, face shields, shoe covers, and gloves
Petechiae
red spots appearing on the skin that are caused by tourniquet that is too tight
phagocytosis
digestion of blood-borne microorganisms that cause infections
phlebotomy
the practice of blood draw
plasma
the yellow-colored liquid component of blood, in which the blood cells are suspended
Quality phletobomy
policies and procedures designed to ensure the delivery of high quality patient care and specimen analysis
reflux
the flow of blood from the collection tube back through the needle and into the patients vein
serum
plasma without its clotting factors, tests performed on serum are called serology
Sharps
needles, lancets, broken glass, and other sharp items
standard precautions
infection control that uses a protective barrier to prevent direct skin contact with blood, body fluids, and tissues from all persons
STAT
a request for immediate attention and processing
Syringe
an instrument used to inject or withdraw fluids, it is simple piston pump consisting of a plunger that fits tightly in a tube; the open end of the syringe may be fitting with a hypodermic needle, a nozzle, or tubing.
therapeutic phlebotomy
removal of blood (bloodletting) as part of a treatment for a disorder
Thixotropic gel
an inert additive used to separate cells from plasma during centrifuging
Thrombosis
clot formation in a blood vessel
tube advancement mark
placed on a needle adapter to indicate how far the tube can be pushed in without loosing vacuum pressure
CLIA
clinical laboratory improvement amendments to our federal guidelines that regulate all clinical laboratories across the united states. Regulations apply to any site that tests human specimens, including small POLs or screening tests done at the patient’s bedside.
Culture and sensitivity (CNS)
microbiology test that determines the growth of infectious microorganisms in bodily specimens and determines which antibiotics are most effective on the microrganism
Allens Test
a procedure used prior to drawing in specimens for ABGs from the radio artery revealed that the ulnar and radial arteries provide collateral circulation to the hand area. Basically, it entails compressing the arteries to the hand and emptying the hand of arterial blood then releasing in the compression to see if the circulation is restored.
EMR
Electronic medical record dash computerized version of medical/clinical records
Hemoglobin Test
measures the level of hemoglobin in the blood, which determines the oxygen-carrying ability
Mean Corpuscular Hgb
determines the average amount of hemoglobin in the average RBC
Hemophilia
blood clotting disorder where the patients blood does not clot and the patient must be monitored closely after blood draws.
