You should report your positive, negative or void results to the NHS.

Interpretation of results

Positive Result

Two lines appear. One coloured line should be in the control line region (C), and another coloured line should be in the test line region (T) two lines, one next to C and one next to T, even faint lines, shows the test is positive.

Important: If you test positive you should self-isolate, your household should follow government guidelines on self-isolating: nhs.uk/conditions/coronavirus-covid-19/self-isolation-and-treatment/
What a positive result means

If you get a positive result, it is likely you are currently infected with COVID-19 and risk infecting others. You should self-isolate. When you report your result, you will be provided with further information on the next steps to take.

Negative Result

One coloured line appears in the control line region (C). No line appears in the test line region (T).

What a negative result means

If you get a negative result, you were likely not infectious at the time you took the test. A negative test result, however, is not a guarantee that you do not have COVID-19. If you test negative, you must continue to follow national and local rules and guidelines, including regular hand washing, social distancing and wearing face coverings, where required.

If you develop symptoms you should self-isolate and get the current recommended test at: gov.uk/get-coronavirus-test or by calling the customer contact centre on 119. Lines open every day, 7am to 11pm.

You and your household should follow national guidelines.

Void Result

Control line (C) fails to appear.

What a void result means

If you get a void result, this means that the test has not run correctly and it is not possible to say if you had the virus when the test was done. You need to use another test from the pack as soon as possible. Do not reuse anything from the first test, and start the test procedure from step 1.

If the problem persists, discontinue using the test kit immediately. Order a new pack of test kits by visiting: gov.uk/get-coronavirus-test, through the NHS COVID-19 App or or by calling the customer contact centre on 119. Lines are open every day, 7am to 11 pm.

You have only completed your test when you have reported your result to the NHS
