Testing the Construction Industry: COVID-19 Antigen Test

Healagen Covid-19 Test


The last 12 months have been testing for the construction industry, but we have all stepped up and remained open over a number of COVID lockdowns. 

Quick, regular testing, using  Public Health England & UK Government assessed tests, reduces the risk of transmission of COVID through the workforce, making building sites safer and more productive without long absences while waiting for testing. UK Government has issued guidance for employers about workplace testing in an article entitled Coronavirus (COVID-19) testing: guidance for employers and third-party healthcare providers.

Test results:

  • POSITIVE - The presence of two lines as control line (C) and test line (T) within the result window indicates a positive result.

  • NEGATIVE* - The presence of only control line (C) within the result window indicates a negative result.

  • INVALID - If the control line (C) is not visible within the result window after performing the test, the result is considered invalid. Some causes of invalid results are because of not following the directions correctly or the test may have deteriorated beyond the expiration date. It is recommended that the specimen be re-tested using a new test.
