I'm not so sure you need to do anything different than you would in any casetaking: look for the symptoms characteristic to the patient's expression of the disease, not at the typical symptoms of the disease. The remedy you need will cover these typical symptoms but it will also, more importantly cover the symptoms which are characteristic to the patient and not the disease. If you think you'll find information that is useful in the patient's history (something consistent, let's say, for the entire case...goes back a long way and remains throughout the case or has been changed by the interventions alone...) then by all means, use it!

By the way, the vet's knowledge of pathology is limited if he's blaming the remedies for the lack of RBC production.
