Cu (toxicity)
Copper measured in the context of heavy metal toxicity screening.
What is it
Copper is essential at normal levels but can be toxic in excess. This measurement is interpreted in the context of heavy metal screening, distinct from copper nutritional assessment.
Why it's measured
Copper toxicity is rare but has been studied in research on Wilson's disease and certain environmental exposures.
Reference range
Standard laboratory reference
70 – 175 μg/dL
Reference ranges vary by laboratory. Your individual reference range will appear on your test report and should be interpreted by your physician in the context of your overall health profile.

It's one of the markers used to build a fuller picture of your health. On its own it tells you very little, so it's most informative when reviewed alongside related markers.
It's measured from a standard blood draw at Quest or LabCorp. Copper (toxicity context) is one of the markers included in the OPTML Apex Panel, where your results are read across systems and reviewed by a U.S.-licensed physician.
Reference ranges vary by laboratory, and a single value rarely tells the whole story. Review your result with a physician in the context of your other markers, symptoms, and history.
