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
