Our Referral Policy

[ + Expand ]

    • The Animal Endocrine Clinic will only perform those laboratory tests, medical procedures, or therapies for which
      the cat or dog has been referred.

    • We will not provide elective or wellness care to cats or dog referred to us by another veterinarian. We do not carry
      vaccines in our facility.

    • If unanticipated diseases or medical conditions are identified during the referral examination or hospitalization period,
      we will promptly contact the referral veterinarian and act in partnership with him or her to decide on the best course of action.

    • In the rare event that critical or life-saving measures become necessary, we will always act responsibly to assure each
      patient’s health and well-being. In such rare cases, we will promptly inform the referring veterinarian as soon as possible,
      and provide daily updates as needed.

    • We at the Animal Endocrine Clinic will always refer clients (ie, owners) back to their primary referral veterinarian after the
      endocrine condition has been evaluated or managed. Once the cat or dog has been evaluated or treated at our facility,
      we will contact the referring veterinarian both by fax and phone to discuss our recommended future follow-up care.
