Differential diagnoses must be considered before choosing a final diagnosis. What criteria must be met before a final diagnosis can be made? Give an example of three differential diagnoses for a patient who complains of a sore throat. Examples GERD, acute pharyngitis, influenza, strep throat. Support your differential diagnoses with a brief statement of reason. You do not have to have a final diagnosis for this patient; just work up the differential diagnoses. This is a common complaint for many patients. To support your work, use your course and text readings and also use the South University Online Library. As in all assignments, cite your sources in your work and provide references for the citations in APA format. References must be in APA format properly along with use of in-text citations.
