Local CWD Testing Facilities — Where Can You Find Them?

Finding Local Facilities

To locate a CWD testing facility near you, start by contacting your state wildlife agency’s wildlife health division. They will be able to provide you with a list of licensed laboratories that conduct CWD testing in your area. You can also search online for veterinary diagnostic laboratories that specialize in CWD testing. Some examples include the National Veterinary Services Laboratories (NVSL) and the USDA’s Animal and Plant Health Inspection Service (APHIS).

Understanding the Testing Process

CWD testing typically involves collecting a tissue sample from a deer or elk, which is then sent to a laboratory for analysis. The most common method of testing is through a rapid frozen section (RFS) examination, which involves examining a thin tissue section under a microscope. This method can provide a positive or negative result within a few hours. Alternatively, a more sensitive test called the immunohistochemistry (IHC) test can be used, which involves staining tissue sections with antibodies that specifically bind to the prions that cause CWD. The IHC test can take several days to produce a result.

Preparing for Testing

Before submitting a sample for testing, it’s essential to follow proper procedures to ensure the accuracy of the results. This includes collecting the correct tissue samples, such as the rectal mucosa or lymph nodes, and handling them properly to prevent contamination. It’s also crucial to provide accurate information about the animal’s history, including its age, sex, and location. This information can help laboratories to better understand the potential risk of CWD and provide more accurate test results.
