Abstract/OtherAbstract:
BACKGROUND: A false-positive sweat test in patients with deficiency of glucose-6-phosphate-1-dehydrogenase (EC 1.1.1.49; G6PD) is repeatedly reported. METHODS: Sweat chloride or conductivity was measured in 11 patients with G6PD deficiency. RESULTS: Mean (SD) chloride level (n = 8, median age 9.2 years, range 1.9-48.5) was 18.8 (9.6 mmol/l) and, mean (SD) sodium level was 26.0 (10.0 mmol/l), respectively, and mean (SD) conductivity (n = 3, median age 6.6 years, range 1.9-40.5) was 34.3 (6.5 mmol/l). CONCLUSION: In sweat of 11 patients with G6PD deficiency we did not find any abnormality. The reason for alleged false-positive sweat test in patients with G6PD deficiency is not known and we were unable to identify any original reference. It appears that tables of putative false-positive sweat tests in several disease states have been directly "copied and pasted" from one paper or textbook to another without verifying the original literature, a phenomenon one can call "chain citation".
