District Health Department No. 4

Providing A Healthier Tomorrow Since 1930

❗️Did you have testing done by the National Guard in Mackinaw City on May 30 or 31?

We are actively working with the state to get the results for the 471 test that were done. DHD4 will report test results when the information becomes available to us but we are not receiving them in a timely manner. Reporting of tests results are backlogged for people that participated that weekend. We understand that waiting for results can be very frustrating.

One way for individuals tested at this event to get results is through the patient portal at bioreference.com/patient-portal. Start by selecting TEST RESULTS then CREATE AN ACCOUNT.

Questions can be directed to the contact information provided below.
