Clinical screenings

Validity has two components: sensitivity and specificity.  The sensitivity of the test is the ability of the test to identify correctly those who have the disease. The specificity of the test is the ability of the test to identify correctly those who do not have the disease (Gordis, 2013).

 

Discuss the Sensitivity and Specificity of different clinical screenings.  Why are they important in clinical screenings?  Calculate the specificity and sensitivity from the following table.
