Saliva Based COVID-19 Prototype Looking for Partners to Bring Kit to Market

A research team based in Iran have been working on detecting the presence of COVID-19 by identifying specific proteins on the viral surface that can cause a colour change in the presence of particular indicator reagents. 

The advantages of using saliva include:

  • specimen collection can be done without a healthcare professional
  • no additional equipment such as swabs or transport media are needed
  • as nasopharyngeal specimens can be 'uncomfortable' use of saliva-based testing may encourage recruits to clinical trials of vaccines.

So far two prototypes have been designed:

1) For Home Testing: Disposable test kits where an individual adds a saliva sample into a vial containing the indicator reagent, the presence of the COVID-19 virus is indicated by a positive test as shown by a colour change.

2) Reusable Low Cost Test Kits for Healthcare Professionals:  Where there is a low concentration of virus in saliva, for example in the first days after infection, viral proteins can be concentrated using a saliva condensation function. In this situation, multiple samples of saliva are placed into a device which can condensate the samples to increase concentration of any virus present. After the test has been completed, the vessel can be disinfected for ready for re-use.

One of the most important properties of this approach is a much lower error rate than has been found in other devices. (errors found in other tests are in various submitted articles to different journals). The re-usable nature of this professional test could make it a practical solution for low-income countries where large scale expensive PCR testing is not an option.
