Phlebotomy 11 Flashcards
suitability to be mixed
compatibility
clumping
agglutination
rupturing
lysis
tracing and testing of blood donors and recipients when a blood product has been determined to be potentially contaminated with a blood borne pathogen
lookback
process where person donates blood for their own use
autologous donation
bacteria in the blood
bacteremia
microorganisms or their toxins in the blood
septicemia
overwhelming, unregulated response by the body to the blood infection that triggers inflammatory responses throughout the body that can lead to tissue damage, organ failure, and death.
sepsis
a persistent fever with no obvious cause; may indicate septicemia
fever of unknown origin
with air
aerobic
without air
anaerobic
active against microbes
antimicrobial
contains charcoal; neutralizes antimicrobial
fastidious antimicrobial neutralization (FAN)
resin removes antimicrobial; used when patients are taking antimicrobial therapy
antimicrobial removal device (ARD)
after a meal
postprandial (PP)
diagnose problems of carbohydrate metabolism
glucose tolerance test (GTT)
blood glucose levels too high
hyperglycemia
blood glucose levels too low
hypoglycemia
determines is a patient lacks the mucosal enzyme lactase, necessary to convert lactose into glucose and galactose
lactose tolerance test
test to determine if a man is the biological father
paternity test
testing of drug levels in the bloodstream at specific intervals
therapeutic drug monitoring (TDM)
must not exceed toxic levels
peak (max) level
must remain within the therapeutic range
trough (min) level
pertaining to treatment
therapeutic
disease involving the body overproducing RBCs
polycythemia
iron overload, especially in the heart, liver, and pancreas
hemochromatosis
scientific study of toxins
toxicology
involving the use of the scientific method in crime investigation
forensics
detailed documentation of specimen tracking from collection to reported results
chain of custody
blood alcohol
ethanol (ETOH)
blood alcohol concentration; test an individual in a traffic accident
blood alcohol content (BAC)
metals; aluminum, arsenic, cadmium, chromium, copper, iron, lead, mercury, selenium, and zinc
trace elements
skin test that require two visits: 1 test, 1 interpretation
tuberculosis (TB) test
test with 1mL blood in four tubes: gray, green, yellow, purple
TB-Gold
alternate site testing (AST) or ancillary, bedside, or near-patient testing; brings laboratory testing to the patient location
point-of-care testing (POCT)
analyzes activity of intrinsic coagulation factors and used to monitor heparin therapy
activated clotting time (ACT)
protime test used to monitor warfarin therapy
prothrombin (PT)
standardizes differences found between reagents in various manufacturer’s tests and allows results from different labs to be compared
international normalized ratio (INR)
abnormally low level of oxygen in the blood
hypoxemia
minerals with electric charge that are present in blood/body fluids, ie. Na+, K+, Cl-, HCO3-, iCa2+
electrolytes
maintains osmotic pressure, acid-base balance, and transmits nerve impulses
sodium (Na+)
too little Na+ in the blood
hyponatremia
too much Na+ in the blood
hypernatremia
aids in nerve conduction, muscle function, acid-base balance, and osmotic pressure
potassium (K+)
too little K+ in the blood
hypokalemia
too much K+ in the blood
hyperkalemia
joins with sodium to make NaCl and joins hydrogen in the stomach to make hydrochloric acid; aids in fluid and pH balance
chloride (Cl-)
transports CO2 in lungs and regulates pH; too much CO2 and H+ leads to acidosis or hypoventilation; too little CO2 leads to alkalosis or hyperventilation
bicarbonate ion (HCO3-)
muscular contraction, cardiac function, transmits nerve impulses, and blood clotting
ionized calcium (iCa2+)
cardiac hormone produced in response to ventricular volume expansion and pressure overload
B-type natriuretic peptide (BNP)
determines bilirubin concentration in the skin of neonates
transcutaneous bilirubin (TcB)
proteins specific to heart muscle; increase in TnT levels signifies four hours of myocardial damage, increase in TnI levels signifies 3-6 hours of myocardial damage
troponin T (TnT) and troponin I (TnI)
beta-globulin made by liver and released into blood after tissue injury; beginning of infection and inflammation
C-reactive protein (CRP)
glucose, which is chemically bound to HgbA
glycohemoglobin
levels reflect average blood glucose level over previous 2-3 months and used to evaluate diabetes therapy
hemoglobin A1C (HbA1c)
Hct measure of RBC volume in blood
packed cell volume (PCV)
fats and fat-like waxy substances the body uses for energy
lipids
“bad” cholesterol because it contributes to atherosclerosis
low-density lipoprotein (LDL)
“good” cholesterol because it carries LDL away from the arteries
high-density lipoprotein (HDL)
