Automated sample annotation for diabetes mellitus in healthcare integrated biobanking.

Healthcare integrated biobanking describes the annotation and collection of residual samples from hospitalized patients for research purposes. The central idea of the current work is to establish an automated workflow for sample annotation, selection and storage for diabetes mellitus. This is challenging due to incomplete data at the time of sample selection.

Optimization of Tumor Dissection Procedures Leads to Measurable Improvement in the Quality of Molecular Testing.

Molecular tests have an inherent limit of detection (LOD) and, therefore, require samples with sufficiently high percentages of neoplastic cells. Many laboratories use tissue dissection; however, optimal procedures for dissection and quality assurance measures have not been established. In this study, several modifications to tissue dissection procedures and workflow were introduced over 4 years.

Performance of fluorescence in situ hybridization in biliary brushings with equivocal cytology: an institutional experience.

Introduction: Biliary brushing (BB) cytology has a sensitivity of 15%-65% and specificity approaching 100% for detecting malignancy. Fluorescence in-situ hybridization (FISH) using the UroVysion probe set has been advocated to enhance the detection of malignancies with reported sensitivity of 43%-84%. We sought to evaluate the performance of FISH in BB with equivocal cytology at our institution.
