Ma Test 5 Flashcards
Analytes
Substance or constituent for which a laboratory conducts testing
Aliquots
Portions of the original specimen
Antibodies
Proteins found in the body in response to foreign substances
Centrifugation
The process of separating blood or other body fluid cells from liquid components
Hypersensitivities
Disorders in which the immune system responds inappropriately to harmless compounds or responds to intensely
Immunohematology
Involves a wide variety of procedures used in donor selection component preparation and use, and techniques used to detect antigen/antibody reactions which may adversely affect a patient receiving a transfusion
Immunology
Testing blasted on the reactions of antibodies in the presence of antigens
Microbiology
The study if pathogen identification and antiobiotic susceptibility determination
Product insert
Contains instructions and critical details for performing a test
Quality assurance
Designed to ensure thorough patient care
Quality control
Procedures to monitor and evaluate testing procedures ,supplies, and equipment to ensure accuracy in laboratory performance
Specimens
Small portions of anything uses to evaluate the nature of the whole
Calibration
A method provided by the manufacture to standardize a year or laboratory instrument
Control
A device or solution used to monitor the test for accuracy and precision
Precision
Similar results if asked to repeat the test
Proficiency testing
Testing programs provide unknown samples to test as if they were patient specimens
Reagent
A substance that produces a reaction with a patient specimen so the analyte can be detected or measured
Sensitivity
The lowest concentration of an analyte that can reliably be detected or measured by a test system
Specificity
The ability of a test to detect a particular substance or constituent without interferences or false reactions by other substances
Trends
When results increase or decrease over time
Albumin
One of the proteins that rarely passes through healthy kidneys
Benedict reaction
Cooper reduction test
Bilirubin
Formed during breakdown of hemoglobin
Glucose oxidase
Chemical reaction to detect the presence of glucose in the urine
Ictotest
Diazo tablet method to detect bilirubin
Ketones
Group of chemicals produced during fat and protein metabolism
Leukocyte esterase
Enzyme reaction that detects pyuria
Nitrite
Positive test that indicates bacteriuria which occurs with urinary tract infections
Nitroprusside
Reaction is used to detect keytones
Pyuria
White cells in urine
Reducing sugars
Sugars including glucose
Sediment
Cells and other matter collect in bottom of tube when centrifuging urine specimen
Specific gravity
Reflects ability of kidney to concentrate or dilute the urine
Sulfosalicyclic acid (SSA)
Common confirmation test for protein in urine
Supernatant
Urine above the sediment when the tube of urine is centrifuged
Urobilinogen
One of the parts of bilirubin when enzymes break into parts
