Rapid Antigen Tests

We firmly believe that screening the population is the best way to identify people in the asymptomatic group and to help contain the spreading of the virus. 

COVID-19 Tests

Three types of tests are available. They all have different specificities and require different types of equipment.

  • Antigen RDT
  • RT-PCR Test
  • Serological Test

Rapid Diagnostic Test (RDT) that detects protein(s) from the virus particle without their amplification.

  • Rapid diagnostic test (lateral flow test)

  • Part of the Antigen tests family

  • Nasopharyngeal swab, fingerstick ,  blood draw or saliva sample type

  • Detects the proteins from a virus particle

  • Test location in a  point of care (temporary installation)

  • No equipment needed

  • Detection around 72 hours after the infection

  • Results obtained in 10 - 20 minutes

  • Sensitivity around 85-95% (the higher the % the less chance of creating false negatives)

  • Specificity around  99% (the higher the % less chance of creating false positives)

Reverse Transcription-polymerase chain (RT-PCR) reaction that detects genetic material through multiple amplification cycles of the viral genetic material.

  • Reverse transcription-polymerase chain reaction

  • Part of the Viral RNA tests family 

  • Nasopharyngeal swab or saliva sample type

  • Detects the viral genetic material through multiple amplification cycles in PCR testing

  • Test location in a complex laboratory

  • PCR machine needed for the test

  • Detection around 0 - 48 hours after the infection

  • Results obtained in 24 - 48 hours

  • Sensitivity around 92 - 99% (the higher the % the less chance of creating false negatives)

  • Specificity around  99% (the higher the % less chance of creating false positives)

Serological Test that detects the presence of IgM and IgG antibodies produced by the white globule cell in the natural body immune response.

  • Rapid diagnostic test (lateral flow test)

  • Part of the Antibody tests family

  • Fingerstick or blood draw sample type

  • Detects the presence of IgM and IgG antibodies

  • Test location in a  point of care (temporary installation)

  • No equipment needed

  • Detection around 7 to 10  days after the infection

  • Results obtained in 10 - 20 minutes

  • Sensitivity around 80-90% (the higher the % the less chance of creating false negatives)

  • Specificity around  99% (the higher the % less chance of creating false positives)

Why Choose Antigen Test

  • Reliable Lateral Flow Assay

    Lateral flow tests (antigen tests) are simple devices intended to detect the presence of proteins from the virus without the need to use any type of specific equipment.

  • Rapid And Efficient

    This type of test only takes a few minutes to develop and deliver test results in 15-20 minutes.

  • Efficient Technology

    Minimally invasive specimen collection with leading sensitivity and specificity. Authorized for nasal and nasopharyngeal sample collection.

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.
