Liquid Biopsies: The Future of Diabetic Foot Care

In this episode of Diabetics with Files, Dr. G explains liquid biopsies — blood tests that detect cell-free DNA and other molecular signals — and how they work. We explore how this technology could help detect infection early, identify harmful inflammation, predict a wound’s healing potential, and personalize treatment for diabetic foot ulcers. The episode also covers current limitations — cost, access, standardization, and need for clinical validation — and explains that liquid biopsies would complement, not replace, clinical exams and imaging. Ultimately, liquid biopsies could shift wound care from reactive to predictive and improve limb salvage in the future.
