Scientific Expertise

Our 20+ years of scientific expertise and clinical experience make us established leaders in the care of patients with urolithiasis by utilizing 24-hour urine chemistries in the metabolic evaluation of kidney stone patients. Litholink, Labcorp's proprietary 24-hour urine product, was founded by Drs Fredric Coe and John Asplin to bring their knowledge and expertise to a wider audience. Our commitment to superior service ensures that our clients receive patient results in a unique graph and table format, accompanied by expert interpretation of the laboratory results. For ordering providers, our medical directors are available for consultation on specific patient results and urolithiasis in general.
