COVID-19 Tests

About

What Are COVID-19 Tests? COVID-19 tests are diagnostic tools designed to detect the presence of SARS-CoV-2, the virus responsible for COVID-19. They are available in several formats to suit different needs, from quick lateral flow tests that deliver results within 15 to 30 minutes to PCR test kits that are sent to a laboratory for highly accurate analysis. With many people choosing to buy COVID-19 tests online in the UK, these kits have become an accessible and convenient way to confirm infection status without attending a clinic. Lateral Flow Tests (LFTs) Lateral flow tests, often referred to as rapid antigen tests, are the most widely used format for home testing. They work by detecting specific proteins produced by the coronavirus, providing a result within approximately 15 to 30 minutes. They are straightforward to use and do not require laboratory analysis, making them ideal for routine or pre-social testing. PCR Test Kits PCR (polymerase chain reaction) test kits are considered the gold standard for COVID-19 diagnosis. You collect a sample at home, typically a throat and nasal swab, and return it to a laboratory for analysis. Results are usually available within 24 to 48 hours and are highly accurate, making them suitable for travel requirements or clinical confirmation. What Are the Symptoms of COVID-19? Recognising the symptoms of COVID-19 can help you decide whether to use a rapid COVID test or seek further medical advice. Symptoms can range from mild to severe and may develop between two and fourteen days after exposure.
