Assessment of iron status in copper-deficient and -sufficient subjects
| Copper deficient | Copper sufficient | |
|---|---|---|
| Hemoglobin (g l−1) | 118.1 ± 3.6* | 129.6 ± 1.1 |
| Ferritin (pmol l−1) | 84.4 ± 21.8* | 213.3 ± 42.3 |
| Vitamin B12 (pmol l−1) | 447.0 ± 55.2 | 497.5 ± 35.1 |
Blood concentrations of hemoglobin, ferritin and vitamin B12 were obtained from patients undergoing roux-en-y gastric patients in study 1 (retrospective chart review) and study 2 (longitudinal study) who had normal copper status (n = 110) and those who developed copper deficiency (n = 25). An asterisk (*) depicts values that were significantly decreased compared with the value in copper-sufficient subjects, P < 0.05.
