In recent years, the U.S. Food and Drug Administration (FDA) has seen an increase in microfluidic medical device submissions, likely stemming from advancements technologies. This trend only been enhanced during COVID-19 pandemic, as microfluidic-based test kits have used for diagnosis. To better understand implications of this emerging technology, submissions to FDA 2015 2021 containing technologies systematically reviewed identify trends applications, performance tests, standards used, fabrication techniques, materials, flow systems. More than 80% devices with platforms were found be diagnostic nature, lateral systems accounting about 35% all identified devices. A targeted analysis over 40,000 adverse event reports linked revealed that flow, operation, data output related failures are most common failure modes these types. Lastly, paper highlights key considerations developing new protocols various applications use certain analytes (e.g., blood, urine, nasal-pharyngeal swab), detection mechanisms.
