Chapter 11 Vocab Key Terms
Term | Definition |
---|---|
ACT | Activated Clotting Time - Determines how long it takes blood to clot |
aerobic | With air |
agglutination | Clumping together, as in the antigen-antibody reaction between RBCs of two different blood types |
anaerobic | Without air |
antimicrobial | An antibiotic used to kill or inhibit the growth of microorganisms |
ARD/FAN | Antimicrobial Removal Device/Fastidious Antimicrobial Neutralization - Antibiotics are removed by these devices |
autologous donation | Blood that is donated for one's own use |
BAC | Blood Alcohol Content - Determines the concentration of alcohol in the blood |
bacteremia | Bacteria in the blood |
BNP | B-type Natriuretic Peptide - Measurement for congestive heart failure |
chain of custody | Special strict protocol for forensic specimens that requires detailed documentation tracking the specimen from the time it is collected until the results are reported |
Cl- | Chloride - Electrolyte responsible for maintaining cellular integrity by influencing osmotic pressure & acid-base & water balance. Needed to produce stomach acid |
compatibility | Suitability to be mixed with favorable results, as in blood transfusions |
CRP | C-reactive Protein - Nonspecific marker for inflammation |
electrolytes | Minerals with an electric charge that are important to heart, nerve, & muscle function. Ex: sodium, potassium, chloride |
ETOH | Ethanol - or blood alcohol |
forensic | Involving the use of scientific methods in crime investigation |
FUO | Fever of Unknown Origin |
glycohemoglobin/HbA1c | Glucose that is chemically bound to hemoglobin A, the primary form of hemoglobin in adults. Used as an indication of glucose control over time. Also called hemoglobin A1c (HbA1c) & glycated hemoglobin |
GTT | Glucose Tolerance Test - A test used to diagnose carbohydrate metabolism problems |
Hb/Hgb | Hemoglobin - Important test in the management of anemia |
HCO3- | An ion that plays a role in transporting carbon dioxide (CO2) in the blood to the lungs & in regulating blood pH. HCO3- is formed in the red blood cells & plasma from CO2 |
Hct/PCV | Hematocrit/Packed Cell Volume - Test that measures the volume of RBCs in a persons blood |
HDL | High-density Lipoprotein - Commonly called good or healthy cholesterol because it is believed to carry LDL (bas cholesterol) away from the arteries |
hemochromatosis | A disease characterized by excess iron deposits in the tissues. Also called iron overload |
hyperglycemia | A condition in which the level of sugar (glucose) in the blood is high, as in diabetes mellitus |
hyperkalemia | A high concentration of potassium in the blood |
hypernatremia | A high level of sodium in the blood |
hypoglycemia | Condition in which the level of sugar (glucose) in the blood is low |
hypokalemia | A low concentration of potassium in the blood |
hyponatremia | A low level of sodium in the blood |
hypoxemia | A low level of oxygen in the blood |
iCa2+ | Ionized Calcium - Ionized form of calcium |
INR | International Normalized Ratio - Standardizes differences in PT results found between reagents in various manufacturers, labs, & countries |
K+ | Potassium - A mineral |
lactose intolerance test | A test used to determine if a patient lacks the mucosal enzyme (lactase) that is necessary to convert lactose, milk sugar, into glucose & galactose |
LDL | Low-density Lipoprotein - Commonly called "bad" or unhealthy cholesterol because it contributes to atherosclerosis |
lipids | Fats & fat-like substances the body used for energy |
lookback | Program that requires all components of a unit of blood to be traceable back to the donor & that also requires notification to all blood recipients when a donor for a blood product they have received has turned positive for a transmissible disease |
lysis | Rupturing, as in the bursting of RBCs |
Na+ | Sodium - Chemical symbol for sodium |
paternity test | Test to determine if a man is the biological father of a specific individual |
peak level | Drug level collected when the highest serum concentration of the drug is anticipated |
POCT | Point-of-care testing - Testing performed where the patient is located |
polycythemia | A disorder involving overproduction of red blood cells |
PP | Postprandial - After a meal |
PT | Prothrombin Time - Test used to monitor warfarin therapy |
sepsis | Life-threatening body response to a blood infection (inflammation, tissue damage, organ failure, & death) |
septicemia | Microorganisms of their toxins in the blood |
T-spot | A type of TB blood test called an interferon-gamma release array (IGRA) that detects TB infection by measuring individuals immune response to TB antigens. Collected in a single green-top tube |
TB-gold | A type of TB blood test called an interferon-gamma release assay (IGRA) that detects TB infection by measuring an individuals immune response to TB antigens. Collected in four special tubes |
TcB | Transcutaneous Bilirubin - Noninvasive way to measure bilirubin in newborns |
TDM | Therapeutic Drug Monitoring - Involves collection of drug levels at specific times |
therapeutic | Pertaining to treatment |
TnT/TnI | Troponin T/Troponin I - Heart muscle proteins elevated after a heart attack. Proteins specific to heart muscle used in diagnosing a heart attack (AMI) & also to monitor the effectiveness of thrombolytic therapy |
toxicology | The scientific study of toxins (poisons) |
trace elements | Metals measured in small amounts that traces of them in the glass, plastic, or stopper material of evacuated tubes may leach into the specimen, causing falsely elevated test values. Ex: aluminum, arsenic, cadmium, chromium, copper |
trough level | Drug level collected when the lowest serum concentration of the drug is expected, usually immediately prior to administration of the next schedules dose |
