Serum copper in a RYGB clinic population. Serum copper concentrations were determined in patients (n = 136) who had undergone RYGB surgery at the Emory Bariatric Center and had visited the clinic for medical and nutritional follow-up during March 2007 and March 2009. Each patient number and their copper measurement(s) is (are) plotted; some patients had multiple clinic visits. Closed squares are values in the normal range, (12.6–24.3 µmol l−1)29, 13 samples are below the normal cutoff and considered deficient (open squares).
