We recommend that feathers or blood samples be taken by an experienced bird handler or veterinarian to ensure the process is free from any unexpected harm to both you and the bird.
When submitting an eggshell, please allow blood stains or the egg membrane to remain attached. This is where we collect the DNA for testing. Ensure that the eggshells are completely dry before placing them in a sealed ziplock bag. A wet eggshell can lead to environmental contamination, promoting the growth of microbes (e.g., bacteria or fungus). This cross-contamination phenomenon can increase the difficulty of DNA extraction and potentially cause the test to fail.
Please change to a new pair of gloves or wash your hands before collecting a sample for the next bird specimen to avoid DNA contamination, which may lead to false results.
