Sample submission
  • Use the correct fixative
  • Tissue samples - 10% Neutral Buffered Formalin
  • Fluids - cytology fixative (methanol)
  • The container should be a suitable size for the specimen; ensure sufficient fixative is used. Ensure the correct lid is used and that it is screwed on correctly to avoid leakage.
  • Samples must be sent with an outer mailing container. Not doing so contravenes mailing regulations and increases the risk of breakage and leakage.
  • Please label the inner specimen pot, not the outer mailer which is re-used. We also recommend that you label the specimen container.
  • Do not use Sellotape to seal the containers. This is time-consuming to remove
  • Absorbent wadding should be included. Samples should be submitted in double waterproof packing with sufficient absorbent material to absorb spills.
  • Label as a pathological specimen and include your name as sender on the packaging.

NOTE: Extra-large specimens should be sliced into carefully and fixed in formalin for at least 48 hours. When the sample is brown rather than red with blood, wrap it in cotton wool or gauze dampened with formalin. Place in a heavy gauge plastic bag and seal, wrap with absorbent material and seal in another bag. Protect with an outer box for posting.
