What it measures
The test measures copper in whole blood, blood cells included, rather than in serum or plasma. Most copper tests use serum, so a whole blood result has its own range and is not directly comparable with a standard copper result.
Why people test it
- Included in some mineral panels that measure several elements in whole blood.
- Looked at alongside serum copper and caeruloplasmin when copper levels are in question.
Typical range
Whole blood ranges differ from serum copper ranges. Ranges vary by lab, method, age and sex, and your report shows the lab's own range.
Finger-prick or vein?
Taken from a vein, and providers offer it only as a vein draw. Ordinary needles and tubes can add tiny amounts of metal, so labs use trace element tubes.
