Test Description
Antech’s stone analysis provides quantitative data on the composition of each stone, evaluating both the core (nidus) and outer layers. Reports include dietary recommendations to guide selection of the most appropriate nutritional profile for the patient, based on the stone’s specific mineral makeup. These insights support individualized dietary and lifestyle strategies to help minimize recurrence risk, as stone composition often reflects the patient’s diet and urinary chemistry.
