Miscellaneous viral infections and diseases 13. PROBLEMS 89-99: Rule-out diagnoses 2: Presumptive diagnosis is based upon the absence of other etiologies combined with a diagnostically appropriate history, clinical signs, and/or pathology. Definitive diagnosis is based upon presumptive evidence combined with further, more extensive work-up with a specific identification of the problem 89. Nutritional deficiency 90. Hypercarbia 91.
