Posting your sample

We provide everything you need to post your sample to our lab – including prepaid postage.


Package your sample

Place your sample in the specimen bag and seal it closed. Do not remove the absorbent pad from the bag. Place the bag in the white collection box.


Securely seal the box

Take the blue security seal provided and stick it over the dotted lines on the edge of the box, pressing down gently to ensure it's sealed tight.


Post it in a priority postbox

No need to use any stamps or queue at the post office: simply pop your box in your nearest Royal Mail priority postbox. Find out where yours is on the Royal Mail website.
