Is the saliva-based Covid test more accurate in tracking Omicron?This is what scientists say

Health experts point out that saliva-based tests can prove to be particularly useful in detecting viruses caused by Omicron variants, which are known to replicate very quickly in the upper respiratory tract. I am.

Since the outbreak of the coronavirus pandemic, the most reliable method of diagnosing a coronavirus infection has been a swab test, including a nasal examination. Dr. Donald Milton, a respiratory virus expert at the University of Maryland, explained the health expert’s approach, saying that nasal examination is the traditional approach when it comes to diagnosing respiratory infections. I told Reuters.

However, questions about the accuracy of home tests, which also rely on nasal tests, have led experts to argue whether the best way to detect the virus is through the nose. The Health Experts section said that the absolute surest way to test for the presence of the virus is by mouth. According to Milton, the virus tends to appear first in the mouth and throat, and the testing approach adopted during the coronavirus pandemic poses a fundamental problem.

Several studies and studies have also suggested that testing the mouth may help identify the presence of the virus a few days before it appears in the nasal swab. However, the saliva testing approach has its own challenges, along with medical limitations, infrastructure gaps, and most testing laboratories are not equipped to process saliva.

Why saliva testing is useful

In the early days of the pandemic, health professionals and scientists were thinking about the possibility of using saliva to perform the Covid-19 test. Scientists were looking for an alternative to a deep cotton swab nose test that would make people hesitant and afraid to be tested. Scientists were initially skeptical of the usefulness of saliva testing, but by the end of 2020, many studies have found that saliva testing is an appropriate and accurate way to test for the presence of the virus. I pointed out.

Glenn Hansen, a member of the Institute for Clinical Microbiology and Molecular Diagnostic at the Hennepin County Medical Center in Minnesota, has evidence to point out that saliva is as good as a nasal swab when it is collected and processed. I told Reuters. Properly. The study also noted that the virus appeared in saliva a few days ago compared to nasal swabs.

A recent study involving Milton and his colleagues detected the presence of the virus in saliva three days before the onset of symptoms, and testing saliva is 12 times more likely to give a positive result on saliva testing. It turned out to be expensive. Nasal swab-based test. The study has not yet been published in a scientific journal, Reuters reported. The Food and Drug Administration has also approved a number of saliva-based PCR tests that have become useful in testing children in US schools in the past few months.

Health experts, and more importantly, saliva-based tests are particularly useful in detecting viruses caused by Omicron variants, which are known to replicate very quickly in the upper respiratory tract. Points out that can be proved. Studies in South Africa have shown that nasal swab-based testing is more reliable with the delta variant, while saliva-based testing is more useful with the omicron mutant.

However, definitive evidence that the scientific community can help curb the pandemic epidemic before the government takes decisive steps in adopting a saliva-based testing infrastructure. It is important to provide.
