Obtaining Samples
Accuracy starts with the sample
Proper sample collection is the most critical step in ensuring the 99.9% accuracy of our testing. The integrity of the biological material—whether feathers, eggshells, or blood spots—directly impacts the laboratory's ability to extract DNA. By following our precise instructions, you help minimize environmental contamination and ensure a swift, reliable result for your avian companions.
Freshly Plucked Feathers
Highly Preferred. The gold standard for DNA testing in both chicks and adults. Freshly plucked feathers contain active follicle cells on the root tip.
Accepted DNA Sample Types
Accuracy begins with the sample. We utilize high-precision PCR technology to extract genetic data from various biological sources. High-grade results depend on collecting clean, high-quality samples that are free from cross-contamination.
Post-Hatch Eggshells
Ideal for Breeders. Most efficient for newly hatched chicks. DNA is extracted from the blood vessels in the inner shell membrane. Minimizes stress by avoiding bird handling.
Blood Spot
Specialized marker tests. Though less common for standard sexing, blood cards are excellent for ensuring enough DNA is submitted for testing.

Preparation
Wash hands thoroughly or use fresh nitrile gloves between birds. Cross-contamination can lead to inconclusive or mixed results.
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.
Labeling
Place feathers in a clean Ziploc bag. Label with the bird ID and submit with the printed submission form.
Step-by-Step Selection Guide
Proper sample collection is vital for genetic accuracy. Clean hands and fresh material ensure our laboratory tech can provide the 99.9% accuracy your flock deserves.
COLLECTION PROTOCOL
Blood Spot Collection

2
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.
3
Dry
Allow the blood to air dry completely for at least 2 hours at room temperature. Keep away from direct sunlight.
Labeling
Place in a clean Ziploc bag. Label with the bird ID and submit with the printed submission form.

Mailing/Drop Off Instructions
Place all labeled sample bags into a single padded envelope or box. Include a copy of your online order submission forms. Mail or drop off to our North Carolina laboratory. Samples may be mailed using a carrier of your choice.

Sample Submission
420 Raymond Tharrington Road
Louisburg, North Carolina 27549
Preparation
Select clean, recently hatched eggshells with membrane intact.
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.
Labeling
Place shell in a separate Ziplock bag labeled with bird ID and printed submission form.
Common Questions
Can I use feathers found on the ground?
No. DNA is located in the live follicle. Shed feathers quickly lose viable genetic material and are often contaminated.
How long are the samples valid?
When stored in a cool, dry place, plucked feathers and dried blood spots remain viable for up to 3 weeks before analysis.
Frequently Asked Questions
How long are feathers or membranes stable for testing?
Feather follicles and blood cards are highly stable. When kept dry and stored at room temperature, they remain viable for several weeks. Eggshell membranes should be mailed within a few days of hatching for optimal DNA extraction results.
Can I send multiple birds in a single shipping envelope?
Absolutely. You can include samples from your entire flock in one package. It is critical, however, that each sample is individually sealed in its own labeled bag or pouch to prevent any cross-contamination between specimens.
What is the minimum age for testing day-old chicks?
Molecular gender testing can be performed effectively on day-old chicks. We recommend nail clipping for blood spot or using the membrane from a fresh eggshell for immediate sexing results.
How long does it take to get my certified lab results?
Once our technicians receive your package, the standard turnaround time is 1 business day. All efforts will be made to post results the same day.You will receive an automated email as soon as your secure results are ready.
