Sampling Priority
                   CWD samples should include both the obex and the medial retropharyngeal lymph nodes
                   (MRLN) when possible.

                   Not every deer is equal in the probability of detecting CWD. Deer exhibiting clinical
                   symptoms and road kills receive high priority. When presented with a high volume of deer,
                   the following priorities should be applied.

                       1.  Sample older-aged animals
                              o  Older aged animals are more likely to contract CWD, and the longer an
                                 animal has the disease, the more likely it is to be detected upon testing.
                              o  The minimum age of an animal to be tested is 1.5 years of age, while 2.5 and
                                 older is the priority.
                       2.  Sampling males over females
                              o  Bucks have a higher probability of testing positive, likely because of their

                   Permission to Collect Samples
                   Landowner permission and signature are required for MDWFP personnel to collect CWD
                   samples on private property. See “Permit and Right of Entry for CWD Sampling” form at
                   the end of the appendix.

                   Sample Information Collection
                   Obtaining accurate location and provider’s contact information for each and every sample is
                   critical. The MDWFP will use Collector for ArcGIS to record all data for each sample
                   collected. This app can be installed on android and iOS tablets and smart phones. All CWD
                   sample information (e.g., Collector, date, location) can be entered on the app. Please refer to

                   Sample Numbering
                   Every sample collected must be numbered with the number found on the top right hand
                   corner of the Biological Sample Tag (Figure 3). This number will be used to track the sample
                   through testing and identify the results back to the pertinent data collected. When dealing
                   with a hunter-harvested animal, the receipt should be given to the hunter. The hunter will
                   then be able to use the receipt number, log into the provided website, and find the appropriate
                   test result.
