What this Trial Is About

Researchers are evaluating new home-based methods to measure medication and chemical concentrations in sweat and saliva compared to standard blood tests in patients with chronic or infectious diseases who are receiving medications. The study aims to see if a smart wristband can accurately monitor substances like electrolytes and metabolites in sweat, which may help in health monitoring and disease diagnosis. This pilot observational study is focused on assessing the feasibility of these wearable sweat sensors. Participants provide sweat samples using a Macroduct Sweat Collection System, saliva samples, and blood samples within 24 hours after taking their medications. They also complete short questionnaires lasting 5 to 10 minutes and allow their medical records to be reviewed. The study collects samples and data to compare the new home-based methods against the standard liquid chromatography-mass spectrometry of plasma. During the study, patients are followed periodically after completing sample collection to monitor results and assess feasibility. Researchers measure how well the home-based sampling predicts medication levels and observe plasma concentrations within 4 hours. The study includes ongoing follow-up to evaluate the ease of obtaining home-based samples and to review medical data over time.
