Patent number: 11959858Abstract: Chronic Kidney Disease (CKD) is characterized by the progressive loss of renal function which eventually leads to End Stage Renal Disease (ESRD). CKD affects roughly 30 million Americans, costs billions of dollars in healthcare spending annually, and leaves thousands of patients reliant on burdensome dialysis treatments while waiting for a transplant. Fortunately, CKD may be controllable if diagnosed early in the disease progression. RAMETRIX™ is a novel public health screening technology for early diagnosis and detection of CKD. This technology uses Raman spectroscopy and chemometrics to analyze the molecular composition of urine and other biological fluids. RAMETRIX™ is a fast, non-invasive, accurate, and inexpensive diagnostic tool that can revolutionize the way healthcare providers detect and treat CKD. The RAMETRIX™ AutoScanner is a system enabling more efficient sample processing in large-scale settings such as hospitals and medical laboratories.Type: GrantFiled: June 11, 2021Date of Patent: April 16, 2024Assignee: Virginia Tech Intellectual Properties, Inc.Inventors: John L.
