Sensitivity and Specificity Calculation
St. Broncoville Regional Medical Center is evaluating whether to
replace annual the current HIV blood test which is sent out to the
reference laboratory with a new HIV rapid test which can be done in
house. Approximately 3% of the 76,000 Broncoville population is HIV
positive. The new HIV rapid test is 97.5% sensitive and 95%
specific. Develop a 2 x 2 table.
Enter only numbers into your answer. Round to two decimal places
after completing mathematical operations. Express your answer as a
percent with two decimal places, but do NOT place a % sign after
your answer.
1. Calculate the Positive Predictive Value (PPV) for the new
rapid HIV test
2. Calculate the Negative Predictive Value (NPV) for the new
rapid HIV test
In the previous question you were asked to calculate the
positive and negative predictive values of a new rapid HIV test.
Interpret your answer. Be specific and thorough using the numeric
values from the previous question to support your
recommendations. Is this a good test? Would you recommend the
new test be used at St. Broncoville Regional Medical Center? Why or
why not?
