You'll need to be a paid mOI member to access testing, and tests are priced separately. Browse and select your tests on the mOI website, then complete your purchase. All tests will be sent to you by post. For blood tests, after your kit has arrived, you'll need to book a phlebotomist to take your blood at home or a location convenient to you. It's important to wait for your kit before booking your phlebotomist to make sure you don't miss your appointment window. Phlebotomy is billed separately: a £99 service fee will be added as a separate line item at checkout. This isn't included in the cost of your test. For gut health tests, once your kit has arrived, it will contain everything you need, together with clear instructions, for you to be able to collect your sample at home.

A trained phlebotomist comes to you at a time that works between 8am and 2pm, Monday to Wednesday. They take your blood sample and centrifuge it on-site before it moves anywhere. Centrifugation spins the sample to separate serum from cells, which has to happen before transit to preserve the integrity of your results. Most at-home testing services skip this step, leaving whole blood sitting in a postal tube while it degrades. mOI phlebotomists do it at the point of collection, the same way a hospital would. They then handle delivery to the lab themselves. You don't need to do anything except be there.

That depends on which test you've taken. A blood test shows how your immune system, hormones, nutrients, and metabolism are functioning right now. A gut test shows what's happening in your digestive system and how it's interacting with your immune health. Whole Genome Sequencing shows how you're built at a genetic level and adds context to everything else. Visit ‘Our tests’ page to learn more about what each test covers.

Over time, and combined with your symptom tracking, your results help you see patterns, understand what's changing, and have more informed conversations with your clinician.

mOI doesn't tell you what's wrong. It helps you understand more about what's happening.

We aim to get your results to you as quickly as possible once your sample reaches the lab, though turnaround times vary by test and occasionally take a little longer for reasons outside our control. Turnaround times are estimates, not guarantees, and are subject to our Terms and Conditions of Sale. Most results appear directly in the mOI app, linked to your health record. They sit alongside your tracking data and insights rather than arriving as a standalone report. For some tests, including certain gut health results, you may receive a PDF report instead of in-app results. Where this applies, it will be made clear at the time. If your membership has lapsed or been cancelled when results become available, we'll deliver them to the email address held in your account instead.

Yes. Testing is only available with a paid mOI membership, and tests are priced separately. Membership gives you access to the full platform, including your results, longitudinal tracking, and the insights that connect your data over time. If you're not a member yet, you can create an account to get started.
