The research, which was not reviewed by the referee, suggested that coronavirus tests may be less likely to give incorrect results when performed in the afternoon compared to other times of the day.
The study, conducted by Candace McNaughton of Vanderbilt University Medical Center in Nashville, United States, and colleagues found that people can cause more covid-related transmission in the afternoon.
New research published in the Guardian report, which has not yet been reviewed by the reviewer, suggested that coronavirus tests may be less likely to produce incorrect results when performed in the afternoon compared to other times of the day.
The results of 30,000 PCR-based tests conducted in Nashville, USA between March and June last year were examined and the most accurate time to test positive within 24 hours was 14.00.
The scientists who carried out the research found that our immune cells interact with the coronavirus and are a repetition of the biochemical, physiological and behavioral rhythms on living things that occur as a result of the daily “circadian rhythm” ( Circadian rhythm; the 24-hour journey of the earth around its axis. In short, it’s not like we can also define it as the biological clock of our body. ) due to the rhythm, the amount of virus transmission may increase in the early afternoon hours.
Previous studies on other viruses, such as influenza, have also shown that an individual’s symptoms and transmission of the virus to others can vary over a 24-hour period.
Dr Rachel Edgar, a virologist at Imperial College London who was not involved in the study but explained it, suggested that changes in our physiology over a 24-hour day could affect the amount of viruses collected in nasal and throat swabs.
