DocNomo is a convenient graphical tool to enhance the bedside interpretation of a diagnostic test result. From the diagnostic sensitivity and specificity of the test and the probability of the patient having the target disorder before running the test (Pre-Test Probability), DocNomo calculates for you the probability of the patient having the target disorder after running the test (i.e. Post-Test Probability). Using the convenience of tactile sliders, each of these parameters may be changed to visually assess their impact on the Post-Test Probability.
DocNomo is the digital adaptation of the Two-Step Fagan Nomogram which is the updated version (2013) of the original Fagans nomogram developed by Dr. Terrence J. Fagan (1975).
