How Our Blood Test Kits Revolutionise Health Monitoring

Our laboratory is calibrated for both venous and capillary blood samples, for equal accuracy. This means we can offer most of our venous tests (walk-in clinic phlebotomy) in a home test kit format. The results are the same and you will have the convenience of doing your sample at home.

Our retest guarantee: We build our kits to work first time, and they do work extremely well. However, should you require a retest or it doesn't quite go smoothly on the day - we'll send you another kit, absolutely free. We are with you for the long run, helping you look after your health.

For any test that you buy as a home kit, we will send you a sample collection box (it's a small box in discreet packaging), where you will find everything you need to collect a blood sample from your finger, at home. This is an easy and safe procedure, it takes about 10-15 minutes in the comfort of your home.

Tailored to Your Needs

With over 300 biomarkers available to test for, One Day Tests have got all your health concerns covered. As well as all the tests that the NHS cover, we offer more specialised tests and can custom-make panels bespoke to your needs.
