The InnoScreenTM COVID-19 Antigen Rapid Test Device is an immunochromatographic membrane assay that utilizes highly sensitive monoclonal antibodies to detect SARS-CoV-2 viral nucleoprotein antigens in respiratory specimens.The control antibody and the SARS-CoV-2 viral nucleoprotein antigen specific monoclonal antibodies are immobilized onto a nitrocellulose membrane as two distinct lines. Nucleoprotein antigen specific SARS-CoV-2 viral antibodies are also conjugated to colloidal gold particles by a proprietary method and then immobilized onto an inert fibrous support. The resulting conjugate pad and striped nitrocellulose membrane are combined to construct the test strip. This test strip is mounted on a plastic backing then fixed into a plastic housing to assemble the test device. Sample is treated with extraction buffer in the extraction tube to release the antigen from specimen before added to the test device. During testing, the extracted antigens bind to anti-SARS-CoV-2 antibodies conjugated colloidal gold particles to form a colored complex. As the specimen migrates along the strip by capillary action and interacts with reagents on the membrane, the complex will be captured by the anti-SARS-CoV-2 antibodies at the test region. Test results are interpreted at 15 minutes based on the presence or absence of pink-to-purple coloured Sample Lines. The presence of pink-to-purple colour Control Line indicates a valid assay.

Eco Test Covid 

Antigen Saliva Pen Test

There has never been a greater need for accurate, simple to use, low cost, rapid testing to enable governments, businesses, schools etc to defend against COVID-19.These easy to use tests serve as a front line defence against asymptomatic people unintentionally causing more infections and shutdowning the workplace resulting in loss of productivity and causing significant added expense.The Ecotest COVID-19 Saliva Antigen Pen is administered under health professional supervision, without the typical discomfort of standard COVID-19 tests.Its easy-to-use, non-invasive, no nasal swab technology means it is also effectivein testing children and the elderly.


Avoid the discomfort of taking nasopharyngeal sample

The COVID -19 antigen rapid test pen is in vitro immunoassay.The assay is for direct and qualitative detection of sars-CoV-2 viral nucleoprotein antigens from saliva samples 




  • child friendly
  • easy saliva sample – no nasal swab 
  • simple 2 step process
