CWD Testing Process — What Do Hunters Need to Know?

April 5, 2026

Quick Answer

Hunters need to know the CWD testing process involves sampling deer heads and submitting them to a lab for analysis, which typically takes 6-8 weeks for results, and that sampling dates may vary by state or region.

Sampling Requirements

When submitting deer for CWD testing, hunters should ensure the head is removed from the carcass within 48 hours of harvest and placed in a sealed bag or container to prevent contamination. The deer head should be submitted to a state wildlife agency or a participating lab, and hunters should check with their state agency for specific sampling dates and locations.

Lab Analysis and Reporting

The lab will analyze the deer head for the presence of CWD prions using a rapid test or immunohistochemistry (IHC) method, which takes about 6-8 weeks. Hunters can check the status of their sample on the state wildlife agency’s website or by contacting the lab directly. If the sample tests positive for CWD, the state agency will contact the hunter to obtain additional information and may require them to report the positive sample to the agency.

Precautions and Safety Measures

Hunters should take precautions when handling deer that may be infected with CWD, such as wearing gloves and washing their hands thoroughly after handling the deer. CWD is a prion disease, and while it cannot be transmitted to humans through handling infected deer, it can be transmitted to other animals that come into contact with infected deer. Hunters should also be aware of the risks associated with consuming meat from CWD-positive deer and consider having their deer tested before consuming it.
