Clinical Utility
Plasma Chromium concentrations can be used for nutritional assessment in patients on TPN. Plasma concentration reflects day-to-day Chromium variations. The measurement of Chromium in erythrocytes provides a better index of body content than the measurement of Chromium in plasma. Whole blood Chromium is recommended for monitoring following orthopedic arthroplasty.
