Sensitivity
If a person has a disease, how often will the test be positive.
If the test is highly sensitive and the test result is negative, you can be nearly certain that they don’t have the disease
Specificity
The ability of the test to correctly identify pts without the disease.
If the test result for a highly specific test is positive you can be nearly certain that they actually have the disease
