These faecal samples were recently sent to our laboratory packed inside a plastic bread bag and were leaking everywhere on receipt. They provide a good example of inappropriate/illegal sample packaging.
Plastic bags tear easily, are prone to leakage, are awkward to extract samples from, do not meet the legal requirements for biological samples and are not an acceptable sample container for any sample type. We request you use the regular/compliant hard plastic, yellow-lidded sample pottles.
If you are unsure of your legal requirements for shipping samples you can find all the information required on our website here.
