If you did an NHS rapid lateral flow test, you should report the result of a home test as soon as possible. Find out about how to report your NHS test result. Antibodies are proteins that your immune system makes after mounting a successful immune response to the virus that causes COVID Molecular tests and antigen tests are the two types of tests that can tell you if you currently have COVID Molecular tests generally take longer but are more accurate. When taken within 5 days of the onset of your symptoms, they correctly identify a positive test more than 90 percent of the time, if done within 5 days of symptoms, according to a study.
However, the effectiveness of the test in identifying the presence of the new coronavirus quickly decreases to roughly 70—71 percent between days 9 and During a PCR test, your doctor typically takes a swab of your nose and throat. The sample is then sent to a lab for processing. Clinics that can process your results onsite may be able to provide you with your results within hours. Clinics that have to send away for results — or clinics with a backlog of tests — may take a week or more to return your results.
Rapid PCR tests are now available, although there is some concern among healthcare professionals about their accuracy. Results usually take 24 to 48 hours. You will receive a text message from the laboratory to let you know that your test is positive. The laboratory will notify ACT Health at the same time. See where to get tested in the ACT.
Do not stop at any shops, cafes and restaurants, or your workplace during this journey to and from the testing clinic unless there is an emergency.

That's why we can guarantee overnight results," said Sandy Walia, founder and director of Clear The company also offers same-day testing, which Walia called "the private jet of testing. The price for a rush test result? Molecular tests are more sensitive than rapid antigen or lateral flow tests, meaning they detect the virus, including the Omicron variant , early and before an individual is contagious in some cases.
They are gentle and non-invasive, meaning patients are no longer required to practically have their brains tickled with a long, thin nasal swab. Walia expects that current strict testing requirements for travel, which vary by country, will eventually loosen, and demand for overnight and faster results will recede.
But testing will remain crucial for preventing the global spread of new variants.
