Dogs incredibly accurately and quickly detect various objects and creatures due to smell and their incredibly developed sense of smell – that is why they are actively used in police and search works related to crimes and drug trafficking. However, today a team of specialists from the BioScentDX research laboratory, specializing in the study of the characteristics and possibilities of smell of various living beings, presented the results of their research on how accurately trained dogs can determine the presence of harmful cancer biomarkers in blood samples of patients suffering from it.
As an experiment, experts conducted preliminary training for participating dogs consisting of four beagles, and then proceeded directly to the experiment itself – and despite the fact that only three beacons participated in the experiment itself (since the fourth was not sufficiently motivated for the experiment), scientists received really eloquent and unusual indicators of the accuracy of the olfactory determination of blood samples in which cancer cells were actually present.
More specifically, scientists have achieved 97% accuracy in detecting cancer cells by dogs using a rich set of olfactory receptors of their nose. At the same time, a team of scientists divided the blood samples, in one group presenting the blood of absolutely healthy people, and in another group of patients with cancer. These results, however, were somewhat expected, since earlier studies in this context led to approximately the same indicators – however, the accuracy of the detection of infected blood samples by dogs is not surprising.
Thus, having acquired the final test results, the team came to the conclusion that it is necessary to use these results and the talents of trained bigli to create and test a conceptually new and more effective type of oncological diagnostics – which can be particularly useful and necessary at an early stage of oncological development. diseases.
