An onsite coronavirus test is the key to keeping your workplace safe and operational. According to recent data, 80% of COVID-19 infections are mild or asymptomatic [1], which means that one or more of your employees could be attending work as usual and unwittingly infecting other members of your workforce.

There are two options for onsite coronavirus testing: an antigen or an antibody test. Both are CE marked for workplace use, easy to administer, and give results within 15 minutes. Both tests can be performed by the individual themselves, supervised by a health professional, or by a company nurse or Occupational Health personnel.

Onsite antigen coronavirus testing

The COVID-19 Antigen (Ag) Rapid Test can detect whether an individual has an active case of COVID-19 and is therefore likely to be infectious to the rest of the workforce. The onsite antigen test can detect a current infection after the onset of symptoms or from 14 days after initial exposure to the virus.

The sample collection involves using a sterile swab (much like an extra-long cotton wool bud) to collect a sample from the nasal and throat areas. The swab is then mixed with a buffer solution and placed in the sample well of the immunoassay device. When the sample flows through the testing device cassette, a quality control line appears. If the result is positive, both the control line and the antigen detection line appear. This means that COVID-19 specific antigens have been detected.

Onsite antibody coronavirus testing

The IgM-IgG Combined Antibody Rapid Test is useful in helping employers to determine which staff might have experienced an historic case of COVID-19. The test can identify an employee’s immunological response to a coronavirus infection from 21 days after exposure to the COVID-19 virus or from 7 days onwards after the onset of symptoms. It can also provide information on the stage of infection.

The test works by detecting both early and late marker IgM/IgG antibodies in a finger-prick blood sample, therefore highlighting a recent infection that may still be active (IgM) or a previous infection (IgG). Interpreting the results are easy. Like the antigen test, lines will appear on the testing device cassette to denote whether a sample is positive or negative.

Why onsite coronavirus testing?

With both the onsite coronavirus antigen and antibody test, if an individual tests positive, they can be immediately removed from the workplace to begin self-isolating. Other staff members can also be identified if they have come into contact with them, further safeguarding employees and limiting any additional spread of the virus. Staff with negative results can safely return to work.

In addition, with regular onsite screening for coronavirus, employers can start to build up a profile of high-risk roles and readjust work practices accordingly. With a virus like COVID-19, we all need to get as much data and information about it as we can. It is only by testing that we can hope to limit its spread.

A further option is AlphaBiolabs’ Rt PCR Laboratory test, which is similar to the antigen test in method but requires a laboratory procedure to determine a result. Samples are processed using the latest, cutting-edge automated PCR extraction methods and results returned within 1–2 days.
