TRIALS show a new test, developed in Southampton, could provide rapid, inexpensive testing of COVID-19

The diagnostic test, developed by the University of Southampton's Zepler Institute for Photonics and Nanoelectronics (ZIPN), can detect the virus that causes COVID-19 in 10 to 15 minutes.

This is much quicker than current testing which requires samples to be sent to a laboratory meaning results are not available until one or two days later.

The new test involves taking a patient’s nasal swab and mixing it with a solution in a tube.

Working in a similar way to the commonly available pregnancy test, a paper strip containing a capture antibody is then dipped into the tube to absorb the solution and as the liquid moves up the strip, a red line will appear if the virus is present in the sample.

The University's Faculty of Medicine have carried out trials using 150 patient swabs, 125 of which had tested positive with a PCR test and 25 that had tested negative.

The results showed the new product can reliably detect COVID-19 in individuals with moderate to high viral levels.

The team are now in discussions with manufacturers who would be able to produce the test on a larger scale and begin the process for obtaining the necessary regulatory approvals.

Dr Collin Sones, the ZIPN lead said: "A cheap rapid test such as ours could complement existing tests being used to control the spread of virus.

"Its key strength is that it can be used at home by anyone, making daily testing of the population an achievable reality.

"The individuals whose samples were identified as positive by our test would be the ones more likely to spread the disease because of their high viral loads."
