Research: Covid-19 can be detected by skin swab

Since the day Covid-19 emerged, PCR tests have generally been used to detect the virus. However, if such insider tests are not done correctly, they can give false results.

Scientists are also working on new Covid-19 tests, and they are working on the use of skin swab samples taken from the outer surface of the body to offer a fast and easy alternative to PCR tests.

With the Surrey study conducted by the UK Frimley NHS Trust, the University of Manchester and Leicester University, scientists have announced that Covid-19 can be detected with skin samples.

SKIN SAMPLES OF 67 PATIENTS WERE EXAMINED

Scientists collected sebum samples from 67 hospitalized patients with a test using an oily, waxy substance called sebum and produced by microscopic glands in the skin. While 30 of these people tested positive for Covid-19, 37 of them tested negative.

Especially when examining the sebum found in abundance on the face, neck or back, it was stated that the lipid levels on the skin of patients with a positive Covid-19 test were lower than those with a negative test.

DIRECT DETECTION RATIO 57 PERCENT, 79 PERCENT WITH OTHER CONDITIONS

While it was stated that this new test method gave 57 percent accurate results in correctly detecting Covid-19 samples as positive or negative, the accuracy rate increased to 79 percent considering the medications and additional health conditions used by patients.

Scientists who carried out the study in the Surrey region in the south of England stated that Covid-19 disrupted the functioning of the body’s metabolic mechanisms, showing that the virus’s ability to affect the body’s internal regulatory processes expanded to the production and maintenance of lipid levels in the skin.

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

‘NEW METHODS WILL BE USED IN THE FUTURE’

Co-author of the study, Dr. Melanie Bailey said, “Our study shows that we can use new methods from the outer surface of the body to test diseases such as Covid-19 in the future. I am sure it will be welcomed by everyone, “he said.

“Covid-19 harms many areas of metabolism. 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 can be a detectable symptom of the disease,” said Matt Spick, one of the study’s authors.
