Rapid Antigen Tests
We firmly believe that screening the population is the best way to identify asymptomatic individuals and to help contain the spreading of the virus.
Our Rapid Antigen Tests
Neobex offers three types of Antigen Tests. They all have different efficacy rates and have their own particularities.
Why Choose Antigen Test?
COVID-19 Rapid Antigen Test Device
The Rapid Response™ COVID-19 Antigen Rapid Test Device is an in vitro immunochromatographic assay for the direct and qualitative detection of SARS-CoV-2 viral nucleoprotein antigens from nasal and nasopharyngeal secretions from individuals suspected of COVID-19 within 6 days of symptom onset. This test is authorized for use at the Point of Care i.e., in patient care setting. Results are for the identification of SARS-CoV-2 viral nucleoprotein antigen. Antigen is generally detectable in nasopharyngeal and nasal secretions during the acute phase of infection.
Positive results indicate the presence of viral antigens, but clinical correlation with patient history and other diagnostic information is necessary to determine infection status.
Negative results should be treated as presumptive, and do not rule out SARS-CoV-2 infection and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions. Negative results should be considered in the context of a patient’s recent exposures, history, and the presence of clinical signs and symptoms consistent with COVID-19, and confirmed with a molecular assay, if necessary, for patient management. The Rapid Response™ COVID-19 Antigen Rapid Test Device is for use at the Point of Care for professional use only.
Pursuant to section 5 of the Interim Order Respecting the Importation and Sale of Medical Devices for Use in Relation to COVID-19, made by the Minister of Health on March 18, 2020, the Rapid Response™ COVID-19 Antigen Rapid Test Device is now authorized for sale or importation in Canada.

SD Biosensor COVID-19 RAPID Antigen Test
SD Biosensor COVID-19 RAPID Antigen Test is a rapid chromatographic immunoassay for the qualitative detection of nucleocapsid antigens to SARS-CoV-2 present in human nasopharynx. This test is for administration by healthcare workers and labs only, as an aid to early diagnoses of SARS-CoV-2 infection in patients with clinical symptoms with SARS-CoV-2 infection.
SD Biosensor provides only an initial screening test result. The result of this test should not be the sole basis for the diagnosis; confirmatory testing is required. To be vigilant against COVID-19 perform a Rapid Antigen Test at least once a week. If there is concern of potential exposure, multiple Rapid Antigen Tests will be necessary.
SD Biosensor remains responsive to the detection of the new COVID-19 variants. The test can also detect active infections in less than 30 minutes, even in those who may be asymptomatic. It identifies those who may be more “contagious” especially from day 2 to 7.

Rapid SARS-CoV-2 Antigen Test
Rapid SARS-CoV-2 Antigen Test Card is a lateral flow immunoassay intended for the comparative detection of nucleocapsid protein from SARS-CoV-2 in nasal swab specimens. Samples are to be collected within 7 days of symptom onset by professional POC healthcare providers in response to individuals reporting suspected symptoms of COVID-19.
Any qualified Health Care professionals can easily use the three-step portable testing kit. Testing can be easily administered in almost any environment without additional special equipment.The result of this test should not be the sole basis for the diagnosis; confirmatory testing is required.
Compared to standard RT-PCR tests which could take multiple days for patients to receive their results, Boson Antigen testers will show results within 15–20 minutes.
