Research Highlights: In this commentary published in the American Journal of Human Biology, Dr. Thomas McDade reflects on the transformative potential of dried blood spot (DBS) sampling over the past decade. He emphasizes how minimally invasive methods like DBS enable researchers to measure key biomarkers in large-scale, community-based studies without the logistical burdens of venous blood collection. As a scientific advisor to Salimetrics, Dr. McDade’s continued leadership in the field underscores the value of our collaboration in advancing high-quality, validated DBS testing. His insights reinforce our shared mission to expand access to biomarker research through innovative, field-friendly methods that bring laboratory precision to everyday health monitoring.
