 Results of monitoring the condition of volunteer HA (22 years old) with an established positive reaction to the H. pylori test, with a violation of the treatment protocol.

Description of the volunteers’ condition at the time of testingComparison of signal fingerprints at zero load level (pink) and after 10 min (blue)Comparison of signal fingerprints at zero load level (pink) and after 30 min (blue)Final conclusion on the sensory assessment of H. pylori, taking into account the accepted hypothesis
HA1.0, H. pylori test not performed, nausea, 16/03/2022The test is positive (+), without inflammation of the esophagus.
I went to see a doctor and was prescribed therapy.

The relative difference in the area of the figures, d, %, correlates with the classification of the degrees of contamination of the mucous membrane of Helicobacter pylori (H. pylori) based on the number of microbial bodies in the field of view: lack of activity (–); the average (++) is up to 40 microbial bodies; high (+++) is more than 40 microbial bodies.
