Our science correspondent, Hannah Devlin, looks into a new technique could cost a 10th of a PCR test:
Scientists have developed a highly sensitive Covid test that relies only on low-tech kit and a smartphone, which could be used as a quicker, cheaper alternative to PCR testing.
The team behind the 25-minute saliva test say it provides a highly reliable platform for testing in the workplace or at home. It requires a basic lab kit that includes a cardboard box, a small hot plate and LED light that can be produced for less than £75. The cost of running a test, including the reagents, is about a 10th of a PCR test and is also cheaper than a lateral flow test. The team’s findings are published in the journal JAMA Network Open.
“As new Covid variants emerge globally, testing and detection remain essential to pandemic control efforts,” said Dr Michael Mahan, of the University of California, Santa Barbara and lead author. “Nearly half the world’s population has a smartphone, and we believe that this holds exciting potential to provide fair and equal access to precision diagnostic medicine.”
The app, which is freely available, uses a smartphone’s camera to measure colour changes indicating a chemical reaction and determines a diagnosis in 25 minutes. When tested in 50 patients with Covid, it matched PCR testing for sensitivity. The same technique was also applied successfully to diagnosing flu infections.

All the money spent on getting science to be exact and precise and now they want to use your mobile phone camera to produce your test result. Great idea but really?
My phone camera is blurry, jumpy and colours keep flitting between different shades. Think I need a new phone.
