Accuracy of genetic test
...Accuracy of genetic test A genetic condition is found that affects 10% of adults in the U.S. population. In a city with 100,000, that means that approximately 10,000 people have the condition, and 90,000 people do not. Fortunately, there is a genetic test for the gene that causes the disease. The test has an error rate of 1% (that is, 1% of people tested get the wrong result). This means that if we test all 100,000 people. Of the 10,000 people who have the condition, 1% of them will have false negatives. In other words, this test will not detect the condition in 1% of the people who actually do have the condition. If false positives also occur at the rate of 1%, then about...
