With results in only 15 minutes, the COVID-19 Antigen Test is a nasopharyngeal swab test which detects the COVID-19 Antigen. Early detection allows more efficient and effective control of the virus.
An Antigen test detects the presence of a specific viral antigen, which implies current viral infection.
this means that among 1,000 people who have had coronavirus, 967 of them will correctly test positive.
this means that among 1,000 people who have not had coronavirus, 999 of them will correctly test negative.
A negative covid 19 antigen test result means that the test did not detect the presence of the COVID-19 antigen in your nasal secretion.
Please Note: A negative result does not rule out the presence of COVID-19 antigens (and hence covid-19 infection) as they may be present below the minimum detection level. The amount of antigen in a sample may decrease as the duration of illness increases e.g. specimens collected after 10 days are more likely to be negative. A negative test therefore should not be used as the sole basis for treatment or patient management decisions.
A negative test result is still accompanied by the advice to wear a face mask, practice regular hand hygiene and follow social distancing recommendations
A positive test result means that the test did detect the presence of the COVID-19 antigen in your nasal secretion. A positive result would suggest that you are currently infected with COVID-19.
A positive result does not rule out co-infections with other pathogens.
As this is a preliminary test, a positive result warrants further PCR testing.
If a Patient receives a positive Antigen test result they should be instructed to:
Contact their GP for instruction.
