Chromium, Plasma

Test ID: HCR P

Test

Method

ICP-TripleQ MS

Platform

Inductively Coupled Plasma Triple-Quad Mass Spectrometry

Report Includes

Chromium

Specimens

Avoid gel separator tubes; Plasma (K2-EDTA)

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.
