Urinary cell-free DNA is a biomarker for infection

We recently analyzed over a hundred samples of urine supernatant from patients who received kidney transplants. Most patients who receive kidney transplants will have an infection in the first few years after receiving their transplant. Thus, it is tremendously important for biomarkers to predict urinary tract infections. We found urinary cell-free DNA to be an sensitive and accurate measure of bacterial UTIs and has the ability to predict viral UTIs weeks before the patient attended the physician with symptoms.
