Currently, there are various methods for diagnosing sexual infections, which differ in sensitivity, ease of use and accessibility. Experience in the treatment of sexually transmitted infections shows that the appointment of diagnostic measures and necessary tests to detect the disease requires an individual approach and the development of new, more informative Express methods. Goal: To investigate easily volatile organic compounds of various classes characteristic of a certain type of sexually transmitted infections. Many STI pathogens, multiplying in the nutrient medium of the mucous membranes of the internal genitals, emit light-volatile organic compounds of various classes, including alcohols, aldehydes, carboxylic acids, aliphatic and aromatic amines, etc.These compounds can be considered marker gases and their presence in the test sample indicates the development of the disease. The most frequently diagnosed STIs are characterized by individual odor secretions and the composition of the equilibrium gas phase (RGF) above them. It is possible to use the method of piezo-quartz micro weighting, based on the selective absorption of STI marker gases by thin highly specific films-modifiers of piezo – quartz resonators.
