Accepted DNA Sample Types
Accuracy begins with the sample
Blood Spot
Blood samples are preferred because they provide the highest DNA quality and the most reliable results.
Freshly Plucked Feathers
Feather samples may contain limited genetic material, increasing the likelihood of inconclusive or delayed results.
Post-Hatch Eggshells
The most efficient method for newly hatched chicks. DNA is extracted from the blood vessels in the inner shell membrane, minimizing handling stress.
Step-by-Step Selection Guide
Feather Collection
01. Preparation
Wash hands thoroughly or use fresh nitrile gloves between birds. Cross-contamination can lead to inconclusive or mixed results.
02. Extraction
Pluck 2 to 3 feathers from the chest area. Ensure they are plucked, not shed, as fresh follicles contain the DNA required for testing. Do not touch the bulbs.
03. Labeling
Place feathers in a clean Ziploc bag. Label with the bird ID and submit with the printed order form confirmation.
Blood Spot Collection
01. Clip & Blot
Sanitize a pair of clippers. Snip the very tip of a toenail and blot one or two drops of blood directly onto the edge of a coffee filter or printer paper.
02. Dry
Allow the blood to air dry completely for at least 2 hours at room temperature. Keep away from direct sunlight.
03. Labeling
Place in a clean Ziploc bag. Label with the bird ID and submit with the printed order form confirmation.
Eggshell Collection
01. Preparation
Select clean, recently hatched eggshells with membrane intact. Fresh material ensures optimal DNA extraction results.
02. Collection
Let the shell dry completely. It is best to send both halves of the shell to allow the tech to select the best part to use.
03. Labeling
Place shell in a separate Ziplock bag labeled with bird ID and printed order form confirmation.
Submission & Mailing
