How Do Sensitivity and Specificity Affect False Positives and False Negatives?
- False Positives: A test with low specificity will yield a high number of false positives, meaning that many people without cancer will be incorrectly diagnosed as having it. This can lead to unnecessary anxiety, further testing, and even treatments that are not needed. - False Negatives: A test with low sensitivity will yield a high number of false negatives, meaning that many people with cancer will be incorrectly diagnosed as not having it. This can delay treatment and negatively impact prognosis.
