Rapid Saliva Protein Test | Medusa19

Rapid Saliva Protein Test

The Rapid Saliva Protein Test (RSPT), from Medusa 19, provides results on the spot in 15 minutes. It is a lateral flow test (LFT) using a simple saliva sample to indicate the immune response to infection, particularly in patients who do not know they have an active SARS-CoV-2 infection and have no specific symptoms.

The RSPT is a simple, non-invasive, on the spot test indicating the immune response to infection from SARS-CoV-2, the virus underlying COVID-19. The LFT requires a simple saliva sample, a comfortable and non-invasive collection process, providing rapid results within 15 minutes.

Developed in the UK and Spain, the test indicates a user's immune response to SARS-CoV-2.

Relative sensitivity of 92%, relative specificity of 98% and 97% accuracy.

How Does It Work?

Sample | 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.

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 | Medusa19

The Science Behind the Test

At the early stage of infection, human cells produce an immune response and generate immunoglobulin G (IgG), but more specifically, immunoglobulin M (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.

Our tests have been developed by industry-leading scientists with over 25 years experience in the medical devices industry.

Delivering Results

The Rapid Saliva Protein Test (RSPT) has a relative sensitivity of 92%, relative specificity of 98% and 97% accuracy.

Sensitivity measures how often a test correctly provides a positive result for people who have COVID-19, whilst specificity measures how often it correctly delivers a negative result for those without the virus. The accuracy is the overall accuracy between sensitivity and specificity.
