Serum
Clinical Utility
Serum Chromium concentrations can be used for nutritional assessment in patients on TPN. Serum 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 serum. Whole blood Chromium is recommended for monitoring following orthopedic arthroplasty.
