Company Description: 

In today’s healthcare system, disease diagnosis often relies on invasive procedures, such as biopsies, which enable direct interrogation of cellular and tissue health at the suspected source of disease. Due to their invasiveness, cost, and general inconvenience to the patient, biopsies are often conducted after onset of symptomatic disease presenting one of the largest barriers to delivering interventions early in disease progression when they are likely to be most impactful. Flagship Labs 103, Inc. is a privately held early-stage company that is building advanced technological and computational platforms to pioneer the detection of cellular dynamics from minimally invasive biospecimens that can be leveraged to connect individuals to the most effective interventions to prevent onset and progression of disease
