Week 2: Genetic Counselling Principles and Practice Flashcards
Analytical Validity
Ability of a test to accurately detect specific characteristics
Clinical Validity
Ability of a test to accurately detect clinical status
Analytic Accuracy
Agreement of the result with the true value of the analyte
Analytic Precision
Reproducibility; agreement between measurements
Analytic Sensitivity
The lowest level of the analyze that can be detected
Clinical Sensitivity
Frequency of positive results when the disease is present
Analytical Specificity
How well the test detects only the analyte in question (VUS reduction)
Clinical Specificity
Frequency of a negative test when the disease is not present
Clinical Utility
Ability of the test to affect positive outcomes
Positive Predictive Value
% of positive results that are true positives
Negative Predictive Value
% of negative results that are true negatives
When giving risks, always follow up by:
Addressing emotional impact
Representative Heuristic
An individual’s interpretation of probability is affected by prototypes or idealized examples
Availability Heuristic
An individual’s understanding of probability is influenced by actual or dramatic instances
Anchoring Heuristic
An initial value is adjusted to yield a final estimate
