We offer on-line diagnostics questionnaires, developed by former faculty members of Johns Hopkins University School of Medicine. One questionnaire, The Pain Validity Test, can predict with 95% accuracy who will have moderate or severe abnormalities on the correct medical test. Then the Headache Diagnostic Test gives diagnoses with a 94% correlation with diagnoses of Johns Hopkins Hosptial doctors, while the Pain Diagnostic Test gives diagnoses with a 96% correlation with diagnoses with Johns Hopkins Hosptial doctors. The B2C website is www.DiagnoseMyPains.com and the B2B website is www.PainValidityTest.com. The B2B tests offers recommendations for the correct medical test for each diagnosis, based on Johns Hopkins Hospital protocols.
