How it works

Step 1 Icon | Medusa19
Sample | Medusa19


Suck your cheeks to collect saliva and spit into the tube up to the 1ml line. Do not count froth or bubbles.

Step 2 Icon | Medusa19
Test | Medusa19


Dispense all of the buffer solution into the tube. Screw the cap back onto the tube and shake vigorously for 10 seconds.

Step 3 Icon | Medusa19
Activate | Medusa19


Squeeze and release the pipette 3 times inside the tube, filling the pipette so the bulb is at least half full. Using the pipette, slowly drop 7 droplets into well B of the Lateral Flow Cassette.

Leave the Lateral Flow Cassette to conduct the test and read the results after 15 minutes. 

The Science Behind the Test

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.

Medusa 19 Life Sciences also hold ISO 13485:2016 certification, and cGMP Good Manufacturing Practice Certification for the quality production of medical devices.

How many tests do you have in stock?

We always aim to have at least 2 million units in stock readily available. Our production line is entirely scalable to meet customer needs.

Can you provide biohazard bins and equipment to undertake the testing?

As the RSPT is a saliva test and doesn’t require blood, they can be disposed into general waste.

Do the tests need to be stored in any specific conditions?

The tests should be stored between 4 and 30 degrees Celsius. All packaging indicates the appropriate temperature for storage.
