Excalibur is nasopharyngeal - Bojo says no no to those!
How Does It Work?
This test is administered at the point of care, near-patient setting. ie, clinic, surgery, designated administration office in the workplace, aesthetic or dental clinic, home or designated test space.
The Excalibur Rapid Covid test uses a single nostril swab test (nasopharyngeal swab) to collect samples from the nasal cavity.
Once the sample is collected, it is processed using a fluid called extraction buffer. The sample is placed in an extraction tube with approx 4ml of buffer . After just 1 minute, the specimen is placed on an antigen test card, An accurate positive test result can be read from the card in a little as 2 mins. A complete test requires 15 mins to reveal if individual tests positive or negative for SARS-CoV-2 the virus that causes COVID-19.
