Module 1 Introduction Flashcards
1
Q
Congenital
A
- Present at birth
2
Q
Disease
A
- Change in normal body function/structure
- Leads to abnormal function
3
Q
Etiology
A
- Study of the causes of disease
4
Q
Genetic
A
- Heritable disorder
5
Q
Iatrogenic
A
- Disease caused by medical treatment
6
Q
Idiopathic
A
- Unknown cause of disease
7
Q
Incidence
A
- Number of new cases of disease/illness
- Within given population during time period
8
Q
Morbidity
A
- Health impairment by illness
9
Q
Mortality
A
- Causing death
10
Q
Pathogenesis
A
- Progression of disease
- Production & development of disease
- Sequence of cellular events
11
Q
Prevalence
A
- Number of cases of given disease
- Within population during time period
12
Q
Prognosis
A
- Predicted course & outcome of disease
13
Q
Sign
A
- Objective measurement
- Found through physical/clinical examination
14
Q
Symptom
A
- Subjective
- Complaint from patient
15
Q
Teratogen
A
- Chemical, biological, physical agent
- Causes physical defects in embryo
16
Q
Gross Exam
A
- Observe with eye
17
Q
Uses of Lab Tests
A
- Diagnosis of disease
- Screening of disease
- Determine illness severity
- Determine course of management
- Monitor surgical recovery
- Drug monitoring
- Identify drug abuse/poisonings
- Baseline/nutritional
- Legal protection
- Verify abnormal results (retest)
18
Q
Serum Specimen Collection
A
- Without anticoagulant (red) top
- Allow blood to clot
- Centrifuged & separated from cells
19
Q
Serum Seperation Tube (SST)
A
- Provide physical barrier
- Serum & cells after centrifugation
- Gold top
- Better stability & transport
20
Q
Plasma Specimen Collection
A
- With heparin to prevent clotting
- Green top
- Centrifuged & separated from cells
- Faster process with small volume (no clot)
21
Q
EDTA Plasma Collection
A
- Preserve cellular elements of blood
- Lavender top
- Hematology tests
22
Q
Accuracy
A
- Ability of data to match true value
23
Q
Precision
A
- Closeness of data to each other
- Spread of data from average
24
Q
Specificity
A
- Absence of disease
- Negative test in non-diseased subjects
- TN/TN + FP
25
Q
Sensitivity
A
- Power of test
- Positive result in diseased subjects
- TP/TP + FN
26
Q
Pre-Analytical Errors
A
- Highest frequency of errors
- Specimen retrieval
