DNA via Egg Shell Membrane

Egg Shell Membrane Sample Instructions (DNA Testing)

Sample Type:
Egg shell pieces containing membrane with a visible blood spot or vein, approximately quarter-sized.

Place each egg shell sample in its own plastic baggie.

Collection Guidelines

1. Prevent Cross-Contamination

• After handling each egg or bird, wipe fingers and all tools (tweezers, clippers, scissors) with a fresh alcohol wipe.

• Use clean tools between birds to avoid mixing DNA.

• Store each sample in a separate, labeled baggie.

2. Handling the Egg Shell Membrane

• Select shell pieces that contain:

  • A small blood spot, or

  • A dried membrane area with visible vein material

• The ideal piece is about the size of a quarter.

• Avoid collecting large, wet, or overly bloody membrane sections that may spoil.

3. Storage Before Shipping

• After bagging, you may store egg shell samples in the freezer. This helps reduce clotting and preserve tissue quality.

• Freezing is NOT required during shipping as long as:

  • Membranes contain minimal moisture, and

  • Samples are kept in separate, sealed baggies.

Important:
✔ Small dried membrane + a drop of blood = perfectly fine at room temperature
✘ Large wet pieces, full shells, or pooled blood = can spoil during transit and are not recommended
