Home tests
When a test is due, test from home.
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. Start your free trial and you can order one straight away: tests cost extra, with £5 off your first test.
How the home test works
Step 1
Your kit comes by post
Order a kit from your account when you want one, and it comes to your home. You do not go to a clinic.
Step 2
Collect from your upper arm
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.
Step 3
See your result
Post it back, postage paid, to our partner laboratory in Northern Ireland. Results come 2 to 3 working days after the lab receives it, and go on your timeline, read against the lab's own range.
How Tasso+ works
- Not a full blood test: a tiny lancet takes a small sample
- No finger prick, and no needle into a vein
- One button, and a few minutes, at home
- Postage paid both ways
Your home test uses Tasso+, a small device that sits on your upper arm.
It isn’t a full blood test. A tiny lancet inside the device takes a small sample, with no needle into a vein.
Put it on and press its button. It does the rest in a few minutes.
There’s no finger prick, and no clinic to visit.
The lab asks you to drink water beforehand: it helps your blood flow, which makes it easier to collect a good sample.
Post it back to our partner laboratory in Northern Ireland. Postage is paid both ways.
Results come 2 to 3 working days after the lab receives your sample, ready to add to your timeline.
Read your kit’s own instructions before you start.

Most tests end with a PDF. Rowe & Wren puts every result next to your dose and your symptoms, and tells you when the next test is due. No “optimal hormone” promises.

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.

Questions, answered plainly.
How much does it cost?
The first 7 days are free. Then membership is £3.25 a month when you pay £39 a year, which saves 18%, or £3.99 if you pay monthly. Home tests cost extra: £59.99 for the basic thyroid test (TSH, free T4 and free T3), or £69.99 for the full thyroid test, which adds TPO antibodies and thyroglobulin (Tg) antibodies, with £5 off your first test. You order one from your account when you want, from the first day of your free trial. A test is paid for when you order it, separately from membership, and its report is yours to download even if you cancel.
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. 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.
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, SHBG, 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. Your other blood tests sit on the same timeline.
