Pre-treatment diagnostics and patient evaluation

Required pre-radioiodine diagnostics include the following diagnostic tests within 30 days of treatment, preferably from a major veterinary laboratory (IDEXX or Antech):

  • CBC
  • Chemistry Profile
  • T4
  • Urinalysis, +/- urine culture
  • IDEXX SDMA (if available)
  • Blood pressure
  • Chest radiographs (minimum 2 views, ideally 3 views)
  • Abdominal radiographs +/- abdominal ultrasound (most applicable to patients suspected to have, or known to also have, significant non-thyroid disease)

If the cat has been on methimazole or other medical management (carbimazole, etc.) treatment prior to radioiodine treatment, we require the cat to have been off the medication for at least 7-14 days prior to I 131 treatment, and a T4 level at least 7 days after cessation of methimazole

Previous records, including the information above, along with other pertinent information (patient weight history, surgeries, biopsies, etc.) can be FAXed to Cat Hospital of Chicago at 773-478-0605, or emailed to Dr. Currigan using the Contact form.
