Research: Covid-19 can be detected by skin swab

According to research conducted in the UK, it was announced that Covid-19 could be detected using a skin swab test. The study, carried out by scientists from the University of Surrey, found that people infected with Covid-19 had lower levels of lipids in natural fats covering the skin surface.

Since the advent of Covid-19, PCR tests have been used in general to detect the virus. However, such insider tests can give incorrect results if they are not performed correctly. Scientists are also continuing their work on the new Covid-19 Tests, studying that skin swab samples taken from the outer surface of the body can be used to provide a quick and easy alternative to PCR tests..

With the Surrey study, carried out jointly by Frimley NHS Trust of England, the University of Manchester and the University of Leicester, scientists explained that Covid-19 could be detected with skin samples.

SKIN SAMPLES OF 67 PATIENTS WERE EXAMINED

With the test, conducted through an oily, waxy substance called Sebum and produced by microscopic glands on the skin, scientists collected sebum samples from 67 hospitalized patients. 30 of these people tested positive for Covid-19, while 37 tested negative. Especially when examining sebum, which is abundant on the face, neck or back, patients who tested positive for Covid-19 had lower lipid levels on the surface of the skin than those who tested negative.

DIRECT DETECTION RATE 57 PERCENT, WITH OTHER CONDITIONS 79 PERCENT

This new form of testing showed 57 percent accurate results in correctly detecting Covid-19 samples as positive or negative, while the accuracy rate rose to 79 percent when taking into account the drugs used by patients and additional health conditions. Scientists who carried out the study in Surrey, south of England, noted that Covid-19 disrupts the functioning of the body’s metabolic mechanisms, their findings show that the virus’s ability to influence the body’s internal regulatory processes extends to the production and maintenance of lipid levels in the skin.

“Given that samples can be provided quickly and painlessly, we concluded that sebum is worth consideration in the future for clinical sampling,” the researchers said.

‘NEW METHODS MAY BE USED IN THE FUTURE’

Co-author of the study Dr from the University of Surrey Melanie Bailey, on the other hand, said: “Our study shows that in the future we can use new methods from the outside of the body to test for diseases such as Covid-19. I’m sure it will be welcomed by everyone,” he said. “Covid-19 damages many areas of metabolism,” said Matt Spick, one of the study’s authors. In this study, we showed that skin lipidoma can be added to the list, which suggests that it can both have effects on the barrier function of the skin and be a detectable symptom of the disease,” he said.
