Do I return my sample first class, recorded delivery or special delivery?

Return your sample using our Freepost label or envelope included in your test kit.

You don't need to put any other information on the envelope. 

You won't need an address as the Freepost address is registered to the relevant laboratory address.

If you would prefer to guarantee delivery to our fulfilment centres within 24 hours, then you may arrange a special delivery with a courier of your choice.
