Positive Iron Balance in Chronic Kidney Disease: How Much is Too Much and How to Tell?
<b><i>Background:</i></b> Regulation of body iron occurs at cellular, tissue, and systemic levels. In healthy individuals, iron absorption and losses are minimal, creating a virtually closed system. In the setting of chronic kidney disease and hemodialysis (HD), increased iron losses, reduced iron absorption, and limited iron availability lead to iron deficiency. Intravenous (IV) iron therapy is frequently prescribed to replace lost iron, but determining an individual’s iron balance and stores can be challenging and imprecise, contributing to uncertainty about the long-term safety of IV iron therapy. <b><i>Summary:</i></b> Patients on HD recei…
Automated Flow Cytometric Analysis of Blood Cells in Cerebrospinal Fluid
We compared the performance of an automated method for obtaining RBC and WBC counts and WBC differential counts in cerebrospinal fluid (CSF) samples with the reference manual method. Results from 325 samples from 10 worldwide clinical sites were used to demonstrate the accuracy, precision, and linearity of the method. Accuracy statistics for absolute cell counts showed a high correlation between methods, with correlation coefficients for all reportable absolute counts greater than 0.9. Linearity results demonstrated that the method provides accurate results throughout the reportable ranges, including clinical decision points for WBCs of 0 to 10/μL. Interassay precision and intra-assay preci…
