What do I need before I schedule my cat for radioiodine therapy?

Thank you for considering making an appointment at AVMI for radioiodine therapy for your cat's hyperthyroidism. Our goal is to provide the highest quality service in a timely fashion. In general the referral process is expected to proceed as follows:

• Your referring veterinarian diagnoses your cat with hyperthyroidism, usually based on a blood test and physical exam findings, and refers you to AVMI for radioiodine therapy.
• You contact AVMI to schedule an appointment for the radioiodine therapy.
• AVMI creates a digital medical record for you and your cat to which copies of any previous medical records information can be attached.
• AVMI will submit a written request to your referring veterinarian for a copy of your pet's medical records including previous laboratory results and diagnostic imaging studies. To ensure you are familiar with the specifics of the communication between your referring veterinarian and AVMI, you will receive a copy of this request. Because we have no way of knowing what specific laboratory, diagnostic imaging or other testing have previously been performed, our request will be a general request for copies of all laboratory and diagnostic imaging results within the last calendar year. Upon receipt of those records we have no way of knowing if those records are comprehensive. Only you and your referring veterinarian know the dates you took your pet to their office and the testing you paid them to perform. As a result it has to be YOUR responsibility to ensure that we receive copies of all pertinent laboratory and diagnostic imaging testing you want us to use to formulate the details of your pet's radioiodine therapy. Toward that end, please consider either bringing a physical copy of your pet's medical records with you or calling to confirm we have received copies of the specific tests you know to have been performed. Delays in receiving copies of previous testing may result in either duplicate charges for repeated testing or delays in treatment and hence a prolonged hospitalization interval.

Pretreatment Recommendations

While not inexpensive, it is well established that because radioiodine therapy actually cures your cat's hyperthyroidism, ultimately it is the least expensive treatment option and therefore a good investment in your cat's long term health. Like most investments, it is typically preceded by a certain amount of  "due diligence". At AVMI there are NO absolute pre-radioiodine therapy requirements, as each patient is unique and each client's resources will vary. Never-the-less, there are certain tests the results of which provide a comprehensive understanding of the overall condition of the patient and allow us to ensure a more consistently favorable outcome following radioiodine treatment. These tests include:

Laboratory Tests

•   CBC
•   Serum Chemistry
•   Serum Electrolytes
•   T4
•   FELV & FIV screening
•   Urinalysis

These tests are generally performed by your primary care veterinarian to ensure your cat is a good candidate for referral for radioiodine therapy and copies of the results are provided as part of the referral process. Depending on a number of factors including but not limited to 1) the results of these tests, 2) the interval between the date these tests were performed and the admission date for radioiodine therapy, and 3) the condition of the cat at the consultation appointment, repeating any and/or all of these tests as well as performing other tests not included in this list may be indicated. If additional testing is indicated at the time of admission the indicated tests and their costs will be included in an itemized estimate that will be provided at the end of your consultation appointment.
