The New York City A1C Registry

Info. for Patients | Info. for Health Care Providers

An A1C resulttells you what your blood glucose has been over the last 3 months. If your A1C is high, you and your doctor may discuss changes to your diet, exercise and possibly medications. Decreasing your A1C can reduce your chances of having heart, kidney, eye and foot problems. A1C is also used to diagnose diabetes.

Utilizing A1C Registry data, the Health Department implements projects to support patients with diabetes in managing their care. For example, letters were sent to adult patients with high A1C results (over 9%) as a reminder to follow up or return to care. As part of the Registry program, you may have received one of these letters in the mail if you had a high A1C result, or you may have received calls or mailings informing you of free programs.

If you do not want to be contacted, either by letter or phone, about your A1C results through registry-related programs and you do not want your provider(s) to receive your A1C information through registry-related programs, you must submit a “Do Not Contact” request. You can:

  1. Submit an on-line request OR;
  2. Print and mail the completed request form (PDF)
    Other languages: [Español] to the Health Department using the address on the form OR;

  3. Call 311 and ask to be directed to the A1c Registry Program.

Submitting a "Do Not Contact" request will in no way affect the current care you are receiving or information your provider (s) receives from the laboratory directly. In addition, you will still be able to receive resources from your provider(s).
