A new screening test for Lyme disease is developed for use in the general population. The sensitivity and specificity of the new test are 65% and 75%, respectively. Four hundred people are screened at a clinic during the first year the new test is implemented. Assume the true prevalence of Lyme disease among clinic attendees is 15%. Calculate the predictive value of a negative test.

Suppose that your company has just developed a new screening test for a disease and you are in charge of testing its validity and feasibility. You decide to evaluate the test on 1000 individuals and compare the results of the new test to the gold standard. You know the prevalence of disease in your population is 30%. The screening test gave a positive result for 292 individuals. Two hundred eighty-five (285) of these individuals actually had the disease on the...

5. A company is testing a new method for screening for Lyme disease. Before offering the test, the company is interested in finding out how Clinically Sensitive and specific it is and found 600 volunteers suspected of having Lyme disease and who were followed up via a physician over a five year period. 500 tested negative for Lyme. Of these, 20 WERE FOUND TO HAVE LYME 100 tested positive for Lyme. However, 10 of these patients...

The prevalence of undetected diabetes in a population to be screened is approximately 1.5%, and it is assumed that 10,000 persons will be screened. The screening test will measure blood serum glucose content. A value of 180 mg% or higher is considered positive. The sensitivity and specificity of associated with this screening test are 22.9% and 99.8%, respectively . 10. Construct a 2x2 table. What is the positive predictive value? What is the negative predictive value?

Use the following information to answer questions. A new screening test for Lyme Disease is being evaluated. It was administered to 1,235 people in southern Maine. While 115 people with the disease tested positive for it another 47 people who do not have disease tested positive for Lyme. 721 people who did not have Lyme tested negative. [Data are fictitious but realistic.] Using the data above, complete a 2x2 table:
