Background: Soluble transferrin receptor (sTfR) is a useful marker in the differentiation of anemia. Clinical utility is limited by lack of standardization between measurement procedures and interpretative recommendations. Our objective was to evaluate the analytical performance of a research sTfR immunoturbidimetric assay (Alinity c, Abbott Diagnostics) and compare it to three established measurement procedures.

Background: The objective of this study was to compare The Binding Site's Freelite on Optilite and Diazyme's Kappa/Lambda free light chains (K/L FLC) on Abbott Architect c8000 with healthy and renal insufficient populations and to evaluate their respective reference intervals for serum free light chains (sFLCs).

Methods: Two hundred sixty serum samples were measured for creatinine and sFLCs by both assays and a subset by immunofixation electrophoresis. Verification of manufacturer-defined reference intervals was assessed.

Background: We evaluated analytical and Sigma performance for 6 next generation chemistry assays on the Abbott Architect c8000 system.

Methods: Albumin with bromocresol purple or green, amylase, cholesterol, total protein, and urea nitrogen were analyzed using photometric technology. Analytical performance goals were defined based on Accreditation Canada Diagnostics (ACD) and Clinical Laboratory Improvement Amendments (CLIA).

Background: Glucose-6-phosphate dehydrogenase (G6PD)/hemoglobin (Hb) ratio helps detect G6PD deficiency, an X-linked disorder that can be asymptomatic or cause acute hemolytic anemia and chronic hemolysis. We investigated preanalytical, analytical, and postanalytical aspects to optimize G6PD/Hb measurement and interpretation.

Methods: G6PD was measured with the Pointe Scientific assay and Hb with Drabkin's reagent on Alinity c® (Abbott Diagnostics).
