What should you know about a free COVID-19 test?

COVID-19 tests look for signs of the virus in a sample, commonly collected from the nose or throat. A positive result supports current infection, while a negative result lowers the chance but may not exclude infection, particularly if testing is done very early or the sample is not collected well. A test does not measure how severe illness will become. Fever, cough, fatigue, headache and feeling generally unwell can have other causes, so symptoms still matter.

Check whether the service is genuinely free, how to book or collect the test, how the sample must be handled and how results are delivered. Follow the kit instructions exactly and avoid sharing a test with another person. While unwell, limit close contact and use local public-health advice. If the result is positive, follow the instructions provided and tell a healthcare professional if you are at higher risk of severe illness. If it is negative but symptoms continue, ask whether repeat testing or another assessment is appropriate.

Get urgent help for marked breathing difficulty, chest pain, collapse, new confusion, blue or grey lips, or inability to stay awake. Contact a clinician if fever is persistent, symptoms are getting worse, or you cannot maintain fluids. A worsening cough with breathlessness may need assessment for pneumonia. Ongoing symptoms after infection should be discussed because Long COVID and other conditions can require separate care.

Ask which test suits your symptoms and timing, how to interpret an unclear result, and whether medicines or health conditions change your risk. Confirm when you should repeat testing or seek examination.
