A new smartphone application can interpret the novel coronavirus or SARS-CoV-2 in serological rapid diagnostic test (RDT) results by combining camera imaging with machine learning, as per an ANI report.

Researchers say the visual interpretation of the results “can be highly subjective” with the application showing “only” 18 false negatives and five false positives from the 3,344 samples tested from 11 RDTs, thus leading them to suggest the application “could increase confidence in RDT tests.”

Moneycontrol could not independently verify the report.

"The app displays results unambiguously (positive, negative, or invalid) without interpretation, translation errors, or jargon. App location data can direct users to local health services for medical advice," the authors said.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

It found that using an app to help RDT users confirm infection presents “strong advantages” such as teaching them through video demonstrations how to perform valid tests or blood sampling schematics. It also noted that the app’s 7-15 minute long “timely reading” reduces the possibility of false positives – helping in human error-free results, and allows for the real-time update of results.

The research further noted that the app only allows “only quality-controlled and locally authorised RDTs to be read.”

Besides, using the app, the researchers suggest that health authorities use fully anonymised location data could produce live disease maps.

The study, co-authored by Paris-based researchers Gary JH Atkinson, Silvestre Bahi, Sandrine Bernabeu, Laurent Dortet, Cécile Emeraud, Delphine Girlich, David A Mendels, Thierry Naas Saoussen Oueslati, and Jean-Baptiste Ronat was published in the Proceedings of the National Academy of Sciences of the US (PNAS) journal.
