Rowe & Wren

The home for managing your thyroid

Make sense of your thyroid.

Rowe & Wren puts your blood results, medication and symptoms on one timeline. You see what changed, and you know when your next test is due. When you need a test, you do it from home.

Planned prices: membership £12.99 a month. Home tests cost extra, from £50. Early access is for adults in the UK with an underactive or overactive thyroid, and it is free to join.

Know when to test.

How often you need a blood test depends on where you are now. Rowe & Wren tells you when a test is due. When no test is due, it tells you that too.

These are the usual schedules in UK clinical guidance. If your clinician gives you a different schedule, use that one.

When a test is due, test from home.

Home tests are part of the service. A small device on your upper arm collects the sample, so there is no finger prick and no clinic visit. Each result goes directly onto your timeline.

How the home test works

Planned price · from £50 a test

  1. Step 1

    Your kit comes by post

    We send a kit to your home when a test is due. You do not go to a clinic.

  2. Step 2

    Put the Tasso+ device on your upper arm and press one button. It collects a small sample in a few minutes. There is no finger prick.

  3. Step 3

    See your result

    Post the sample to a UK laboratory. Your result goes on your timeline, with a plain explanation.

After your test

  1. When a result arrives

    See what has changed

More than another blood test.

Most home tests end with a PDF. Rowe & Wren puts each result next to your dose and your symptoms, and tells you when the next test is due. It is only for thyroid conditions, and it makes no “optimal hormone” promises.

The founder of Rowe & Wren

Why we started

Rowe & Wren started with a diagnosis.

Our founder has hypothyroidism. After her diagnosis, she was not satisfied with the care and support that she got.

She wanted to understand accurately what was happening in her body, and to learn what was behind it. So she started Rowe & Wren: one place to see your results, your medication and your symptoms together, and to know when to test next.

Questions, answered plainly.

How does the home test work?

We post a kit to you. You put the Tasso+ device on your upper arm and press one button. The device collects a small blood sample in a few minutes, with no finger prick. You post the sample to a UK laboratory, and your result goes on your timeline.

How much does a test cost?

Home tests are part of the service, and each test is an extra cost. The planned price is from £50 for a basic thyroid test, and a fuller thyroid test costs more. The planned price of the membership is £12.99 a month. You buy a test only when one is due.

How often do I need a test?

That depends on where you are now. With an underactive thyroid, the usual schedule after a new diagnosis or a dose change is a test about every 3 months, until your results are steady. After that, it is once a year. With an overactive thyroid on antithyroid medicine, tests are more frequent. If you plan a pregnancy or you are pregnant, you need tests more often, and your GP, midwife or specialist sets the schedule. Rowe & Wren keeps the schedule for you.

Does Rowe & Wren replace my GP or endocrinologist?

No. Rowe & Wren supports health tracking, education and conversations with qualified healthcare professionals. It does not diagnose conditions, and it does not recommend medication changes on its own.

Can I add results that I already have?

Yes. Upload results from the NHS or from a private provider, then add your medication, symptoms and important health changes. A test from us is optional.

Who is early access for?

Adults in the UK with an underactive thyroid (hypothyroidism), an overactive thyroid (hyperthyroidism) or Hashimoto’s. This includes people who plan a pregnancy and people who are pregnant.
