Your complete history will be required by your veterinary professional as he collects his diagnostic information. This history will need to include dietary and feeding information like the type of feed offered, the frequency of feedings, whether the horse is turned out for pasture or field forage or if it is fed a hay and grain diet. You will likely need to determine the potentially poisonous plants which are within access of your horse, samples being provided if necessary. This will help the vet pinpoint the possible source of the poisoning or sickening of your horse. He will do a physical examination of your equine and assess the condition of it.

The veterinarian may need to collect blood and tissue samples for laboratory testing to determine if any of the blood components are out of balance, to determine if there are any bacterial or fungal components in the poisoning and to determine if there is any parasitic activity involved. Since many of the symptoms of this poisoning are similar to many other conditions and diseases known to horses, he may order radiographic imaging (x-rays) and CT imaging to rule out other causes. Once he has gathered all of this information , he can formulate and implement an appropriate treatment plan for your horse.
