Please give details to solve the following question:
Calculate the value based on this information. A new screening test for Lyme disease is developed for use in the general population. The sensitivity (ability to identify infected persons) is 60% and specificity (ability to identify non- infected persons) is 70%. 300 people are screened (assume the true prevalence of Lyme disease is 10%) The predictive value of a positive test is:© BrainMass Inc. brainmass.com June 4, 2020, 4:17 am ad1c9bdddf
Since the sensitivity is 60% and specificity is 70%, we can make use of the following table for all calculations:
The solution gives detailed steps on computing predictive value of a positive test. All formula and calcuations are shown and explained.
