HOW THE ANTIGEN PCR TEST WORKS
The back to lab antigen test looks for the presence of the COVID-19 virus to determine if someone has COVID-19 at the point in time the test is taken.
The virus is detectable at highest accuracy 1-3 days after symptoms appear. The test can also pickup SARS-CoV-2 (COVID-19) up to two days prior to symptoms appearing and 5 days post symptoms appearing.
The test works in the lab by looking for the RNA of the virus through real time PCR. A real time PCR test works by detecting the genetic signature of the virus. This genetic signature can be present before the body has symptoms or has had a chance to produce the antibodies.
ACCURACY OF RESULTS
The Antigen test we provide at DNA Workplace has been trialed
extensively and found to have the following accuracy:
Sensitivity 98% - confirming almost all cases of active COVID-19
virus are detected.
Specificity 100% - confirming no false positives.
A positive test confirms infection however a negative test does
not rule out the person having COVID-19 in all capacities. All
negative tests should be repeated if the patient is showing
Please note that this test does not indicate whether you have
had the COVID-19 virus recently or in the past.
Testing can be carried out by the staff member either at your organization’s offices or at the staff members home. Online training is provided to ensure the collection process is strictly followed otherwise the result may be invalid.
Where the sample will be taken:
• Mouth and Nose Swab (UK & USA)
• Mouth Swab (USA)
After the collection is completed, the kit is sent to the designated laboratory.
Within 2-3 working days results are released to the nominated clinical lead or representative for your organization who is responsible for delivering the
information and advice to the staff members.
