Unsaturated iron-binding capacity: a screening test for C282Y hemochromatosis?
with “BD SST 1 double centrifugation” (P ,0.0001, paired t-test). Deming regression analysis yielded the following: slope 5 1.16 [95% confidence interval (95% CI), 1.03–1.29]; intercept 5 0.04 mg/L (95% CI, 0.02– 0.06 mg/L). Table 1 shows the assay values of the six apparently falsepositive results. These results prompted a second phase, during which the BD Thrombin sample was also centrifuged ...
متن کاملAutomated measurement of unsaturated iron binding capacity is an effective screening strategy for C282Y homozygous haemochromatosis.
BACKGROUND C282Y hereditary haemochromatosis is an appropriate condition for population screening. Transferrin saturation, the best screening test to date, is relatively expensive, labour intensive, and cannot be automated. Unsaturated iron binding capacity is a surrogate marker of transferrin saturation and its measurement can be automated. AIMS To evaluate a screening strategy for C282Y her...
متن کاملRedox active plasma iron in C282Y/C282Y hemochromatosis.
Labile plasma iron (LPI) represents the redox active component of non-transferrin-bound iron (NTBI). Its presence in thalassemic patients has been recently reported. The aim of the present study was to quantify LPI in HFE genetic hemochromatosis (GH) and to characterize the mechanisms accounting for its appearance. We studied 159 subjects subdivided into the following groups: (1) 23 with iron o...
متن کاملIntravenous iron-dextran: studies on unsaturated iron-binding capacity.
A method is described for measuring the plasma unsaturated iron-binding capacity in the presence of very high concentrations of iron as iron-dextran. The procedure utilizes (59)Fe to label the apotransferrin with subsequent separation of ionic iron from transferrin-bound iron on an ion exchange or Sephadex G.25 column. The unsaturated iron-binding capacity has been measured in rabbits and dogs ...
متن کاملIron absorption in carriers of the C282Y hemochromatosis mutation.
Hereditary hemochromatosis is a disorder of iron homeostasis in which the body iron content may be greatly increased. Most patients with hereditary hemochromatosis are homozygous for the C282Y mutation of the HFE gene. Because the iron content of the body is regulated by modulation of iron absorption, the increased body iron of those who are homozygous for the C282Y mutation must be due to enha...
