In the study conducted by the National School of Veterinary Medicine and Necker-Cochin Animal Hospital in France, dogs proved to be more successful than lateral flow tests (LFT) used to get fast results in bulk areas. A recent review of 64 studies found that LFTs correctly identified an average of 72 percent of people infected with the virus with symptoms and 58 percent of people without symptoms.
Within the scope of the research conducted by scientists, various samples and cotton pads pressed under the armpits for two minutes were collected from 335 people between the ages of 6 and 76. The pads were then sealed in jars and sniffed to nine dogs used in the trial. The dogs detected 97 percent of 109 people whose PCR test was then positive and 91 percent of those who were PCR test negative.
Professor Jean-Marc Tréluyer, one of the researchers involved in the study, said the following on the subject: “It is quite impressive that dogs give faster and more accurate results in case detection than lateral flow tests. Unfortunately, this success of dogs cannot replace polymerase chain reaction (PCR) tests, which are more reliable than LFT tests. Dogs can only help identify people who need a complete viral test. Because the dogs’ response is so fast, they can facilitate collective testing in places such as airports, railway stations, and concert halls. “
Finland and the United Arab Emirates began using sniffing dogs at international airports in Helsinki and Dubai last year, while researchers in countries such as Australia, Germany, and the UK were experimenting with dogs to detect Covid-19.
