Comparison of the newly formulated beckman access free T4 (Thyroxine) assay on the DXI 800 analyzer with the current Beckman free T4 (Thyroxine) assay for biotin Interference: New assay is free from biotin interference.

Background: Biotin causes significant positive interference with Free T4 (thyroxine) measurement using the current Beckman assay. Recently, Beckman reformulated the FT4 assay to overcome biotin interference. We compared the effect of biotin on both current and newly formulated FT4 assays.

Clinical Evaluation of the Heparin Therapeutic Window Using Activated Clotting Time in Neurological Interventional Radiology at an Academic Medical Center.

Context.—: Activated clotting time (ACT) is useful for monitoring heparin therapy in neurointerventional radiology (NIR). We previously used the Hemochron Signature Elite instrument for measuring ACT in NIR.

The hierarchy of needs for laboratory medicine requires a foundational care delivery model.

Under the collective weight of growing test volume, staffing constraints, and Medicare reimbursements cuts, an enhancement-based, alternative payment structure focused on rewarding the laboratory's care delivery efforts via benchmarking is appealing. However, achieving a value-based payment model requires the development of an inclusive laboratory care delivery model (LCDM) framework. Today, a holistic, practical LCDM framework for laboratory medicine does not exist.
