A group of investigators has developed a new diagnostic test for the detection of a serum marker, TAK, which is a structural component of the CG-23 capsule. A study is evaluating the performance of the new test among 500 healthy subjects who are followed-up for the development of symptoms. Blood is also withdrawn for real-time polymerase chain reaction (RT-PCR) analysis, the gold standard test for the detection of CG-23 DNA. The infectious organism's DNA is detected in 100 individuals by RT-PCR. The sensitivity and specificity of the novel test are 90% and 80%, respectively. What is the probability that a subject with a positive result in the new diagnostic test truly has the disease? C General Principles 2020-10-27T23:07:59Z 2459150.4638773 WBR0038
