How  accurate and reliable are pathology tests?

The value of any sort of test can be assessed in two ways; firstly - does the test give the correct answer and secondly - is the test reproducible, in other words, does it give the same answer each time it is used. These are the concepts of accuracy (getting the correct answer) and precision (getting the same answer each time the test is used).  These two concepts are not the same as it is possible to consistently get the wrong answer with a test or to get the correct answer but with a broad spread of results.
