Access to Ultra-Fast, Reliable COVID-19 Antigen Saliva Tests

Rapid and efficient screening tools are an essential step in the global fight against COVID-19 and key to ensuring a safe return to daily life and social interactions. Today, nucleotide-based testing (RT-PCR) is the gold standard for diagnosing the disease. But, while sensitive, these tests are limited by long turnaround times, high costs and a typically invasive and uncomfortable nature of sampling.

The 1-Minute COVID-19 Saliva Test Delivering Results Right Where You Need Them

Abionic’s COVID-19 saliva test allows for ultra-fast screening, using the abioSCOPE device to ensure lab quality results at the point-of-care. The device’s intuitive design combined with single-use kits enables COVID-19 testing to be done in a secure manner, reducing the need for trained personnel and personal protective equipment (PPE) 1. The user-friendly saliva swab ensures a discreet and non-invasive sample collection directly from the mouth, followed by 4 simple steps to read the capsule immediately.

Results are immediately sent to the patient in an electronic COVID-19 patient report, linked to a QR code.

What Does Abionic’s COVID-19 Test Measure?

The IVD CAPSULE COVID-19 test on the abioSCOPE device measures the presence of a specific SARS-CoV-2 viral antigen in saliva. The SARS-CoV-2 virus contains 4 structural antigens or proteins:

  • Spike glycoprotein (S)
  • Envelope protein (E)
  • Membrane protein (M)
  • Nucleoprotein (N)

The N protein is the package encompassing the viral RNA. It is abundantly expressed during COVID-19 infection, and if found in saliva, indicates an ongoing infection.The N protein is detected by the IVD CAPSULE COVID-19 antigen test on the abioSCOPE®, and is recognized by many health authorities as being the most valuable antigen to be targeted by rapid COVID-19 antigen tests1.

FAQs

An antigen test measures the presence of viral particles in saliva, if you have an ongoing SARS-CoV-2 infection, you will have these antigens present in your saliva.

SARS-CoV-2 antigen particles were found in saliva at the start of the pandemic. This was later confirmed in studies that found that the virus infects and replicates in epithelial cells of salivary glands 2. Comparisons of diagnostic test performances with matched nasopharyngeal and saliva samples have confirmed the suitability of saliva as a sample type for SARS-CoV-2 testing and has today gained scientific attention and approval by competent health authorities1,3.

An RT-PCR test detects the presence of SARS-CoV-2 using a molecular biology technique which amplifies the virus’ genetic material. In comparison, the antigen test will detect the presence of viral particles in the mouth directly. Since there is no amplification step, antigen tests are easy to perform on the spot and provide results within minutes.

The IVD CAPSULE COVID-19 test is read on the abioSCOPE® device, which is a small medical device that uses revolutionary nanofluidic technology to accelerate the interaction between molecules, reducing the time to results down to less than 1 minute. Compared to lateral flow techniques, Abionic’s nanotechnology ensures that lab-quality results can be obtained in an electronic COVID-19 health certificate with QR code, even at the point-of-care and in an ultra-fast time.

The IVD CAPSULE COVID-19 detects all known variants of SARS-CoV-2. Abionic Researchers continuously assess the product's performance regarding the evolution of the pandemic and the understanding of the disease. As the test targets the nucleoprotein (N) antigen, there is a lower risk that a novel variant might impact the test performances compared with tests targeting the spike (S) protein 4.
