Should I Test?
Visual aids designed in collaboration with Dr. Daniel Morgan of the University of Maryland to help medical professionals understand the benefits, risks, and results of tests.
The guides ask in visual language: What difference will it make in the patient's life? What is the likelihood of the disease given the patient's history? And what would a positive test mean?
A warm/cold color contrast represents positive and negative results. The form of a dial is used to consider pretest probability, and two waffle charts compare the chance of a true-positive versus false-positive results based on the patient's background. An icon system helps doctors see at a glance what percentage of a test result is a true and false positive or negative.
