Lab Test: Copper (Blood) Level
|
|---|
- Measurement of copper in serum for evaluation of copper deficiency, toxicity, and disorders of copper metabolism.
- Adults: 70-140 mcg/dL (11-22 micromol/L)
- Infants, 0 to 6 months: 20-70 mcg/dL (3.1-11 micromol/L)
- Children, 6 years: 90-190 mcg/dL (14.1-29.8 micromol/L)
- Children, 12 years: 80-160 mcg/dL (12.6-25.1 micromol/L)
- Pregnancy (at term): 118-302 mcg/dL (18.5-47.4 micromol/L)
- Levels in African-Americans are 8% to 12% higher
- Pregnancy complications secondary to suspected copper deficiency - severe maternal copper deficiency can result in embryonic and fetal abnormalities
- Suspected idiopathic copper toxicosis - serum copper and ceruloplasmin levels are normal or slightly elevated.
- Suspected Indian childhood cirrhosis - plasma copper concentration may be normal or elevated
- Suspected Menkes syndrome - serum copper < 11 micromoles/L (< 70 micrograms/dL)
- Suspected Wilson disease - typically present with hypocupremia (40 to 60 mcg/dL), low ceruloplasmin levels and an increase in urinary copper excretion.
- Results increased in: women, patients with dilated cardiomyopathy, immediately after myocardial infarction.
- Diurnal variations occur with highest levels noted in the morning.
