Introduction: Calcium (Ca) isotope marker (CIM) measured in serum (δ44/42Ca-serum) and urine (δ44/42Ca-urine) have been demonstrated in earlier studies (c.f. Eisenhauer et al. 2019, David et al. 2023) with a restricted number of participants to be a sensitive, reliable and minimal invasive BCaB marker. The purpose of this surveillance study was to further refine and confirm the validity of the CIM approach to a larger randomized number of people not selected based on specific criteria, but rather showing a wide range of diseases and therapies.
