Home tests

When a test is due, test from home.

Your year includes a full thyroid test. A small device on your upper arm collects the sample, so there is no finger prick and no clinic visit. Our UKAS-accredited partner laboratory in Northern Ireland tests it, and the result goes on your timeline. Order yours from Tests in your account.

The Tasso+ device on an upper arm — How the home test *works*

Result
TSHThe brain’s signal telling the thyroid how much hormone to make. TSH is a hormone from a small gland at the base of the brain. It tells the thyroid how much hormone to make. When thyroid hormone is low, TSH goes up. When it’s high, TSH goes down. What your blood test shows Read the film’s words A usual thyroid blood test looks at TSH and free T4, and sometimes free T3. Many labs test TSH first, and only add the others if it isn’t normal. Guidance for doctors is to test TSH first. If TSH is above range, free T4 is tested from the same blood sample. If it’s below range, free T4 and free T3 are. A TSH above range means the body is asking the thyroid for more hormone. A high TSH with a low free T4 suggests an underactive thyroid that needs treatment. A high TSH with free T4 in range is called a mildly underactive thyroid. Each lab gives a range: what it sees in most healthy people. Your result is compared with it. Lab ranges are only a guide and vary from lab to lab, so each result is read against the range on its own report. People may feel well even when their thyroid tests are outside the range. High-dose biotin supplements can make thyroid test results wrongly high or low. The British Thyroid Foundation quotes the American Thyroid Association’s advice to stop biotin supplements two days before a thyroid blood test. Guidance for doctors is not to test the thyroid during a sudden illness, unless the thyroid may be the cause, because the illness can affect the results.
Free T4FT4Thyroxine, the hormone the thyroid makes. T4 is the main hormone the thyroid makes. The test measures the “free” part, which the body can use. What your blood test shows Read the film’s words A usual thyroid blood test looks at TSH and free T4, and sometimes free T3. Many labs test TSH first, and only add the others if it isn’t normal.

Guidance for doctors is not to test the thyroid during a sudden illness, unless the thyroid may be the cause, because the illness can affect the results.
Free T3FT3The active form of thyroid hormone, made mostly from T4. The body turns T4 into T3, the form it actually uses. Free T3 is usually only tested to check for an overactive thyroid, or how overactive it is. What your blood test shows Read the film’s words A usual thyroid blood test looks at TSH and free T4, and sometimes free T3. Many labs test TSH first, and only add the others if it isn’t normal.

TPO antibodiesTPOAbAntibodies from the immune system, often found in Hashimoto’s. TPO antibodies come from the immune system. They’re high in Hashimoto’s and sometimes in Graves’ disease. More than 9 in 10 people with Hashimoto’s have them, and so do about 1 in 10 people with no thyroid problem. TPO antibodies, in detail Read the film’s words TPO antibodies are raised in Hashimoto’s, and sometimes in Graves’ disease, an overactive thyroid: about 7 in 10 people with Graves’ disease have them. In Hashimoto’s, TPO antibodies usually stay. Levels may fall over time, but hardly ever go back to normal, even once treatment has brought thyroid levels back to normal. With a mildly underactive thyroid, antibodies can mean it may develop into full thyroid disease in future, but treatment isn’t needed yet. In people without a thyroid disorder, TPO antibodies may be a marker of autoimmunity: autoimmune disease may be more likely in future. Someone with autoimmune thyroid disease is more likely to develop another autoimmune condition, such as pernicious anaemia or coeliac disease, but the risk is still very small. Raise it with your doctor if new symptoms appear.
Tg antibodiesTgAbAntibodies checked mainly after thyroid cancer. Tg antibodies are sometimes high in Hashimoto’s. They’re also checked after thyroid cancer, because they can make another test used then less accurate. Tg antibodies, in detail Read the film’s words Thyroglobulin (Tg) is made by thyroid cells. It helps the body make, store and release thyroid hormone. After surgery and radioactive iodine for thyroid cancer, Tg shouldn’t be found in the blood, so it’s measured to keep watch. Tg antibodies are found in about 1 in 10 people. Where they’re present, the Tg result is less reliable, so other ways of monitoring are used too. When TSH is raised, Tg antibodies don’t usually add anything to TPO antibodies. After thyroid cancer, your specialist team reads these results with you.

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.

Underactive thyroid
- New diagnosis or dose change
  About every 3 months
  Until two results in a row are steady and in range.
- Steady on your dose
  Once a year
  The usual schedule when your results do not change.
Overactive thyroid
- On antithyroid medicine
  About every 6 weeks
  Until your TSH is in range. Then about every 3 months, while you take the medicine.
Pregnancy
- Planning a pregnancy
  Before you start to try
  So that you and your clinician can check your level first.
- Pregnant
  More often
  Tell your GP when you know that you are pregnant. Your GP, midwife or specialist sets the schedule.

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

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 received.

So she started Rowe & Wren: one place to see your results, your medication and your symptoms together, and to know when to test next.

The founder of Rowe & Wren

Questions, answered plainly.

How much does it cost?

7 days free, with no card needed. Then £89 for your first year and £99 a year after, with a full thyroid test included. With the HRT check too, £139 your first year, then £149 a year. Tested by your GP? Track your NHS results for £3.99 a month. A test's report is yours to keep, even if you cancel.

What is Tasso+? How does the home test work?

A small device that sits on your upper arm. Press its button, and a tiny lancet inside takes a small sample in a few minutes: no finger prick, no needle into a vein, and no clinic visit. You post it back in the prepaid envelope. Watch the 1-minute film

What should I do before my sample?

Read the kit's instructions first. The lab asks you to be well hydrated, and, unless it was prescribed, to stop taking biotin supplements at least 48 hours before you take your sample.

Who tests my sample?

Our partner laboratory in Northern Ireland, accredited by UKAS to ISO 15189, the standard for medical laboratories. Every home test includes the Tasso+ device, postage both ways and the lab test.

How long until my results?

Results 2 to 3 working days after the lab receives your sample, and with you within a working day of the lab's report reaching us.

What if my sample can't be tested?

If the lab can't test your sample, for example because there isn't enough blood, we tell you and explain what happens next.

Can I have a blood draw instead?

Not from us: our tests are home kits. Your GP can take blood at the surgery, and you can add that result to your timeline.

Do you test anything besides thyroid?

On HRT? The HRT check measures oestradiol, testosterone, free testosterone, SHBG, FSH and LH. It comes with the HRT year (£119 your first year, then £129 a year), or the thyroid and HRT year (£139 your first year, then £149 a year). Each from the same Tasso+ sample.

Can I cancel?

Yes, at any time, in Account. You keep access until the end of the month or year you've paid for, and you aren't charged again. Your record stays, so you can come back to it.

Is my information private?

Yes. Your health record is private to you. The privacy notice says what we keep, who handles it for us, and your rights.

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.

Which results can I track?

Thyroid (TSH, free T4, free T3 and antibodies), iron and vitamins (ferritin, iron, B12, folate, vitamin D), cholesterol, and hormones (oestradiol, progesterone, FSH, LH, testosterone, free testosterone, SHBG, prolactin, cortisol). From the NHS, a private clinic or a home test.

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 Rowe & Wren for?

Adults in the UK with a thyroid condition: underactive, overactive or Hashimoto’s, including in pregnancy. And anyone on HRT who wants to see their levels over time. Your other blood tests sit on the same timeline.
