A new do-it-yourself kit could provide hope for those who hate having a cotton swab stuck up their nose to test for COVID-19.
Developed by scientists at Palacky University in Olomouc, Czech Republic, the self-test involves gargling tap water.
After gargling for around 30 seconds, the water is spat into a test tube that contains a special powder.
The test — which researchers say is as reliable as a nasal swab test — is then sent off to the laboratory.
Marian Hajduch, director of the university's institute of molecular and translational medicine, said: “The test tube contains a powder which helps to stabilise the virus for several days at normal room temperature.
