The diagnosis of hyperthyroidism is a clinical diagnosis
verified by laboratory tests. Because many factors affect thyroid laboratory
test results, one normal value does not exclude the diagnosis in a symptomatic
patient. A medical history, physical examination by a veterinarian, and
diagnostic tests are required to confirm the diagnosis of feline hyperthyroidism.
Pretreatment Evaluations & Tests
In addition to the physical examination, referring veterinarians
perform the following procedures before the cat is admitted:
- Laboratory Evaluation
- Complete Blood Count (CBC)
- Urinalysis with sediment exam
- Complete chemistry/electrolyte panel
- T4 or Free T4 or both
- Electrocardiogram (optional at discretion of referring veterinarian)
- Chest Radiograph (2 views, VD and Lateral)
- Blood Pressure (waived if the patient is extremely anxious)
Laboratory studies and other evaluations may be performed
up to four weeks prior to admission. The Cat Thyroid Center reserves discretion
to repeat any tests after examining the patient. If a cat is referred
without the requisite procedures, pretreatment studies are performed on
site for an additional charge.
Selection Criteria for Treatment
Referring veterinarians must ensure that a cat is fit
for hospitalization and therapy. Dr. Ott accepts only medically stable
cats. The cats we have treated have ranged in age from 4-19 years. Those
with advanced renal disease may be poor candidates and require further
evaluation before they are eligible.
If a cat is currently receiving antithyroid medication,
e.g. Tapazole (methimazole), it must be discontinued at least 24 hours
prior to treatment.
