Test Code CRWB Chromium, Blood
Ordering Guidance
High concentrations of gadolinium and iodine are known to interfere with most metal tests. If either gadolinium- or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours.
Specimen Required
Container/Tube: Royal blue top (EDTA) Vacutainer plastic trace element blood collection tube
Specimen Volume: 1 mL
Collection Instructions:
1. See Metals Analysis Specimen Collection and Transport for complete instructions.
2. Send whole blood specimen in original tube. Do not aliquot.
Useful For
Monitoring exposure to chromium using whole blood specimens
Monitoring metallic prosthetic implant wear
Special Instructions
Method Name
Inductively Coupled Plasma-Mass Spectrometry (ICP-MS)
Reporting Name
Chromium, BSpecimen Type
Whole bloodSpecimen Minimum Volume
0.3 mL
Specimen Stability Information
Specimen Type | Temperature | Time | Special Container |
---|---|---|---|
Whole blood | Refrigerated (preferred) | 28 days | |
Ambient | 28 days | ||
Frozen | 28 days |
Reference Values
0-17 years: Not established
≥18 years: <1.0 ng/mL
Interpretation
Results greater than the reference range indicate exposure to chromium (see Cautions about specimen collection).
Prosthesis wear is known to result in increased circulating concentration of metal ions. Increased blood trace element concentrations in the absence of corroborating clinical information do not independently predict prosthesis wear or failure.
