Traditionally, methods for assessing the acid-base balance in patients are limited to systemic monitoring, however, in recent years, non-invasive pH measurement methods have been developed to assess the intra- and/or extracellular pH of tissues and biological fluids. The aim of the study was to determine the mechanisms of interaction between bromothymol blue and a test system for rapid diagnosis of diseases of the genitourinary tract. The study was carried out on a carrier based on cotton fiber with cellulose filler. It has been shown that the sorption capacity of cellulose is influenced by the pH of the medium, the ionic strength, the nature of the solvent, and temperature. As a result of the study, the mechanisms of the mechanisms of interaction between bromothymol blue and the test system were identified, the conditions of fixation of bromothymol blue on cellulose were identified and the duration of preservation of the properties of the resulting chip in time was investigated.</p>express diagnosticsurinary tract diseasesbromthymol bluepH meterэкспресс-диагностиказаболевания мочеполовых путейбромтимоловый синийpH-метрия
