Abstract

A biomarker detection device is a wearable device utilized to detect and analyze a sample of bodily fluid for the presence of various biomarkers that are indicative of a variety of medical conditions. A microneedle array is inserted into the user'"'"'s skin in order to draw a sample of bodily fluid into an H-filter within the biomarker detection device. A reagent with antibodies is released into the H-filter as well and the antibodies are able to bond to biomarkers within the bodily fluid sample after the sample and the reagent have been mixed. A sensor connected to the H-filter comes into contact with the bonded antibodies and biomarkers. A computing unit electronically connected to the sensor detects the biomarkers bonded to the antibodies and performs analysis to determine if the level of biomarkers present in the acquired sample is unsafe or outside of a “normal” range.
