CWD testing
CWD testing
As a responsible hunter, you understand the importance of monitoring the health of the deer herd for diseases like CWD. Fortunately, options are available to hunters who want to test their deer. We are here to provide the necessary information to help you make an informed decision about CWD testing to keep our deer population healthy and sustainable.
DNR focused head collection and testing
In 2025, the DNR is conducting focused collection for CWD testing in the following counties. CWD testing is free for deer harvested in these counties when submitted through DNR drop boxes and staffed sample submission sites. All heads tested for CWD are also screened for bovine tuberculosis. Results are posted to the DNR lab results webpage.
- Baraga
- Chippewa
- Dickinson
- Houghton
- Iosco
- Keweenaw
- Luce
- Mackinac
- Ogemaw
- Ontonagon
- Schoolcraft
Free self-sample shipping kit testing
Hunters in all other counties are eligible for free CWD testing by using a free lymph node shipping kit that includes overnight shipping. Hunters must extract lymph nodes themselves to submit to Michigan State University Veterinary Diagnostic Laboratory (MSU VDL) for CWD testing. Kits can be picked up from the locations below. Results from deer submitted to MSU VDL will be sent directly to the hunter from the VDL and will not appear on the DNR lab results webpage.

Due to the risk of bovine tuberculosis (bTB), hunters should not extract lymph nodes from deer harvested in the following counties: Alcona, Alpena, Cheboygan, Crawford, Iosco, Montmorency, Ogemaw, Oscoda, Otsego, Presque Isle, or Roscommon. Please submit heads from these deer to a DNR wildlife field office and request CWD testing in addition to bTB testing.
Hunters should call an office prior to arriving to ensure someone will be available to assist.
