Microsampling techniques find application in various fields, including the collection of small blood samples for analysis and the extraction of portions of otoliths for subsequent analysis. In the realm of blood sampling, microsampling typically involves gathering minute blood samples, often less than 50µl, using minimally invasive techniques like a simple finger prick. This approach proves particularly valuable in applications such as therapeutic drug monitoring and pediatric pharmacokinetic studies, where only a small blood quantity is necessary for analysis. The advantages of microsampling are manifold, encompassing the reduction of the required blood volume for analysis, enabling convenient sample collection at home, and facilitating direct shipment to the laboratory for analysis. These innovations contribute to the advancement of medical research and diagnostics, offering a streamlined and patient-friendly approach to sample collection and analysis.
