COVID-19 Testing: Antigen and Antibody Tests
Antigen Test
Anyone experiencing symptoms of COVID-19 or asymptomatic individuals can undergo an antigen test to determine if they are infected with the virus. This test, also known as the "swab" test, is commonly used for diagnosis.
Test Procedure
The antigen test involves collecting a swab sample from the nose and throat using a cotton bud. Individuals aged 12 and above can self-administer the swab, while children under 12 require assistance from a parent or guardian.
Testing Options
There are two methods of obtaining an antigen test: scheduling an appointment at a drive-through or walk-through testing site, or requesting a home test kit via mail.
Result Interpretation
The test outcome determines whether the individual should continue self-isolating, return to work, or undergo re-testing.
Antibody Test
An antibody test assesses whether an individual has previously been infected with COVID-19, but it does not indicate the level of protection or immunity.
Testing Methods
Antibody testing can be performed through two approaches: a blood sample taken by a healthcare professional, primarily offered to NHS and social care staff, hospital inpatients, and care home residents; and a finger prick self-test for home use.
Current Status
As of July 2020, finger prick self-tests are not widely available due to accuracy concerns. The government plans to offer these tests in the future once more reliable options are accessible.
Result Notification
Upon completion of the test, individuals will receive their results via text or email. Results from test sites may take up to 48 hours, while home test results may require up to 72 hours.
