Read your result in minutes, not days.

Most “home tests” mean posting a sample to a laboratory and waiting several days. Ours don’t. You take the test at home, read the line yourself in five to fifteen minutes, and nothing is sent anywhere. We never see your result.

Home diagnostic test kits, delivered across the UK

Seradiag supplies CE marked rapid diagnostic test kits for home and clinical use. Every kit is a lateral flow test: you collect a small sample, add it to the test cassette and read the result yourself in around five to fifteen minutes. There is no laboratory, no postage and no waiting for results to come back.

How a rapid test kit works

Depending on the test, the sample is a finger-prick blood drop, a urine sample or a saliva or swab sample. It travels along the test strip and reacts with antibodies or antigens printed on it. A control line confirms the test has run correctly, and the test line shows the result. Each kit includes step-by-step instructions, and our test guides explain how to read results and what to do next.

Tests for home and professional use

Our range covers cancer screening, allergy, hormone and general health testing, along with tests for professional and clinical settings. You can browse every test, or use Find a Test if you are not sure which one suits you. If you would like advice before ordering, email us and we will help you choose.

What a result means

A home test is a screening tool, not a diagnosis. A positive result should always be confirmed with a GP, pharmacist or clinic, and a negative result does not rule out a condition if you have symptoms or ongoing concerns. If you feel unwell, speak to a healthcare professional whatever the test shows.

Private, fast UK delivery

Orders placed before 2pm on a working day are dispatched the same day from UK stock, in plain outer packaging with nothing on the label to indicate the contents. Your result stays with you: the test is read at home and nothing is sent to us. See our delivery information and refund policy for details.
