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. Randox Health's 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.
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 Randox Health's 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.
Randox asks you to drink water beforehand: it helps your blood flow, which makes it easier to collect a good sample.
Post it back to Randox Health's 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.
