Diagnosis is the process of determining which disease or health condition explains a person's test results and symptoms.
DDxHub - Differential diagnosis Hub is the System distinguishing of a particular disease or health condition from others that present similar symptoms and lab test results.
DDxHub is a concentrator that holds a lot of disease descriptions. DDxHub is useful when you try to find a right diagnosis by comparing several different possible diagnoses. You may enter your own disease definition into DDxHub repository and share the disorder descriptions with other DDxHub users around the world. In turn, you will be updated with disorder descriptions from other DDxHub users.
