Rapid Saliva Protein Test (RSPT)

 

The RSPT is a non-invasive test indicating the immune response to infection from SARS-CoV-2, the virus underlying COVID-19:

 

–        Provides results on the spot in 15 minutes

–        Less intrusive than a swab or blood test

–        Simple saliva sample required

–        Can be taken on the premises (with a healthcare professional present)

 

It enables businesses with a healthcare professional present to test on a wide scale and build confidence to return to work quickly and safely.

The RSPT works by using a lateral flow device. Users provide a small saliva sample into a tube and add Medusa 19’s novel solution which isolates and solubilises protein structures present in saliva, produced in response to SARS-CoV-2 infection.

 

This mixture is placed on the lateral flow device which migrates the saliva sample along the device. As the sample moves along the device, the antibodies to SARS-CoV-2 that are present in the saliva will attach to chemicals in the device, capturing them on test and control lines.

 

A colour change along these lines will appear depending on the presence of proteins (G for IgG and M for IgM).

 

The results are within 15 minutes

The non-invasive test requires simple saliva collection, and is less intrusive than a blood sample, nasal or throat swab. Developed in the UK and Spain, the test indicates a user’s immune response to SARS-CoV-2, the virus underlying COVID-19.

 

Users provide a saliva sample into a collection tube, mixing this with a solution, which isolates and solubilises the protein structure present in saliva. This mixture is applied to a lateral flow device which migrates the saliva sample along the device. The test identifies antibodies unique to COVID-19, capturing them on test and control lines.

 

The RSPT isolates the protein complexes in saliva, allowing for recognition of saliva antibodies produced after the first contact with the virus, immunoglobulin M (IgM) and immunoglobulin G (IgG). Antibodies are produced when a virus is present as part of the body’s immune system response to infection.

 

At the early stage of infection, human cells produce an immune response and generate IgG, but more specifically IgM at the point of contact with the virus, which for COVID-19 is in the throat and respiratory tract. The antibodies are then transported from the lymph nodes into blood and saliva. In the early stage, detection in blood is not sensitive enough due to a high dilution effect, whereas in saliva, the independent clinical data indicates it is detectable.

  

The test is CE marked to 98/79/EC, registered with the MHRA, and is for use under supervision from a medical professional throughout Europe. It could prove pivotal in helping companies safely reopen workplaces and take action in line with government guidance.

Independent clinical trials demonstrated the following:

Relative specificity 98% (174/177), relative sensitivity 92% (34/37) and accuracy of 97% (208/214)
