Chromium, Serum
Test ID: CR S
Test
Method
HR-SF-ICP-MS
Platform
High Resolution Sector Field Inductively Coupled Mass Spectrometry
Report Includes
Specimens
Avoid gel separator tubes; 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.
