Can I return my test to you over the weekend or a public holiday?

  • Updated

You can, but it's better if you can post your sample back to us on Monday to Thursday, because we want to analyse your sample as soon as possible after you have taken it.


We provide Royal Mail Tracked 24 return envelopes for your sample but Royal Mail has early last collection times on a Saturday and doesn’t deliver to the lab at all on Sundays or public holidays. 

  • If you post on a Saturday morning before last collection - your sample should arrive in the lab on Monday morning.
  • If you post your sample after last collection on Saturday or on a Sunday - your sample will not be collected until Monday and will not arrive in the lab until Tuesday.
  • On Bank Holidays samples posted after last collection on Saturday will not be collected until Tuesday and will arrive in the lab on Wednesday.
