A postal testing service is available from the website. If you order a kit before noon Monday – Friday this will be shipped the same day and should arrive with you the following day. Orders placed after noon Monday – Thursday will be shipped the following day, arriving with you two days after order. Orders placed after midday on Friday will be dispatched on Monday and should arrive with you on Tuesday. You can then post the kit back to the lab.

Samples returned via Royal Mail Priority Post Boxes, Monday to Friday, should reach the lab in the following 24 hours.

Please note that our service is not suitable for those with a Saturday or Sunday ‘test’ date.

All customers purchasing these tests must use their own judgement about the best date to purchase, carry out and return the test to us. Klarity cannot take responsibility for any test timelines and associated outcomes affecting travel.
