"You feel unwell, and visit your doctor. They ask some questions and take some
blood for testing; a few days later they call to say you have been diagnosed
with a disease.
What are the chances you
actually have the disease? For some common
diagnostic tests, the answer is surprisingly low.
Few medical tests are 100% accurate. Part of the reason is that people are
inherently variable, but many tests are also built on limited or biased samples
of patients – and our own work has shown researchers may deliberately
exaggerate the effectiveness of new tests.
None of this means we should stop trusting diagnostic tests, but a better
understanding of their strengths and weaknesses is essential if we want to use
them wisely."
