Serum transferrin, estimated by total iron-binding capacity (TIBC), may be a marker of protein-energy wasting (PEW) in maintenance hemodialysis (MHD) patients. We hypothesized that low TIBC or its fall over time is associated with poor clinical outcomes. In 807 MHD patients in a prospective 5-year cohort, associations of TIBC and its changes over time with outcomes were examined after adjustmen...

BACKGROUND We previously reported the development of a fully automated assay for total iron-binding capacity (TIBC) in serum, using a multipurpose automated analyzer. However, this method requires four different reagents and is thus useful only with a limited number of available analyzers. We simplified our original assay and compared the analytical performance of the modified method with that ...

Ferritin values for 250 selected sera were compared with values for iron, total iron-binding capacity (TIBC), and transferrin saturation, to assess the potential of the ferritin assay for the detection of latent iron deficiency. The specimens were grouped (50 in each group) according to their values for iron and TIBC. In Group 1 (low iron, high TIBC) the saturation and ferritin values both indi...

BACKGROUND Tumor infiltrating B cells (TiBc) have not yet been investigated in detail. This may at least in part be due to technical difficulties. Here we describe a straightforward and reproducible method to isolate and culture TiBc from primary colorectal carcinomas (CRC). METHODS/RESULTS TiBc cultures were generated by Epstein-Barr virus (EBV) immortalization. With this method, monoclonal ...

iron concentration or UIBC value is below detectable limits, TIBC cannot be determined. In conclusion, TIBC values determined by DTIBC assay were strongly correlated with TRF concentrations. The slope of the regression line for the DTIBC values plotted against the TRF is consistent with the theoretical TIBC/ TRF ratio. TIBC values calculated from the sum of serum iron and UIBC were significantl...

The serum iron was determined in 60 normal subjects (38 males and 22 females) with a mean age of 32.0 and 36.2 years respectively. The plasma total iron-binding capacity (TIBC) was also determined in 54 of these subjects (32 males and 22 females). Serum iron and TIBC determinations were performed between 8.45 am and 9.15 am. The mean serum iron concentration is 138.3 +/- 4.3 mug/100 ml (SD +/- ...

We sought to determine if serum total iron-binding capacity (TIBC) is equivalent to serum transferrin (TRF) so that a low-cost colorimetric chemical assay for unsaturated iron-binding capacity (UIBC) could be substituted for a high-cost immunologic assay for TRF. Our study design included independent and blinded measurements of UIBC, serum iron, and TRF concentrations in human serum samples. Da...

I evaluated a commercial electrochemical method (Environmental Science Associates), based on potentiostatic coulometry, for determining iron and total iron-binding capacity (TIBC). The method requires 25 and 100 microL of serum, respectively, for these measurements. Serum iron concentrations so determined in 99 normal volunteers satisfactorily correlated with those determined by the Iron Panel ...

BACKGROUND Present methods for measuring serum total iron-binding capacity (TIBC) involve manipulation of samples or performance of two assays on each sample. We developed a direct automated assay (DTIBC) for TIBC. METHODS We added to serum a saturating amount of iron bound to an excess of chelating dye at a low pH, recorded a blank reading that represented the sum of the saturating amount of...

OBJECTIVE To determine the diagnostic accuracy of serum iron and total iron binding capacity (TIBC) in detection of iron deficiency. STUDY DESIGN Descriptive, analytical study. PLACE AND DURATION OF STUDY Department of Chemical Pathology and Endocrinology, from January 2013 to October 2015. METHODOLOGY Data of 1,815 patients with results of serum iron, TIBC and ferritin from January 2013 ...
