About One Day Tests

A range of convenient at-home testing options are available through One Day Tests, providing you with a simple way to check for various health conditions, including sexually transmitted infections and COVID-19. Each test kit is designed for easy use, allowing you to collect samples in the privacy of your home and send them to a certified lab for accurate results. With a focus on privacy and reliability, One Day Tests aims to make health monitoring straightforward and accessible for everyone.

Why should I use Repayclub for One Day Tests voucher codes?

Because every One Day Tests coupon, discount code and deal on this page is captured and verified by a real person, not copied in by a bot. The card already tells you what the code does and doesn't do – minimum spend, exclusions, first order only, expiry – we read the small print, note the bits that matter, and try the code on One Day Tests's own checkout before it goes live.

We keep looking after that, too. The date listed as "Updated" at the top of this page is when the One Day Tests list was last checked. Codes that no longer work are removed from the list on the same day. If it sounds too good to be true, it doesn't make the list. Cash back is the same – if One Day Tests pays cash back, the rate you see here is the rate you get, paid in real money, not points or vouchers, and you can use a One Day Tests voucher code and still get it on the same order.

One other thing – we only link to the official site of One Day Tests, onedaytests.com. No fake stores, no "download this to get your code", no pop-ups. Choose a code, grab it, shop. That's the whole point.
