Laboratory considerations amidst the coronavirus disease 2019 outbreak: the Spedali Civili in Brescia experience.

Coronavirus disease 2019 emergency has created an enormous stress on providers that have been transformed into coronavirus disease hospitals. This article presents the experience of the clinical laboratory of Spedali Civili in Brescia (a teaching hospital in Lombardy with over 1500 beds) in managing the crisis, and to offer practical considerations for laboratory testing for this cohort of patients. Our contribution is threefold: by comparing the demand for tests in two representative period before and within the crisis, we show the change in compositions of the analytes that other labs may expect; we present the new panels of tests that hospital staff can order with different advantage for wards and laboratory; and we show how to reorganize staff on the basis of changes mentioned above.

Novel bone metabolism-associated hormones: the importance of the pre-analytical phase for understanding their physiological roles.

The endocrine function of bone is now a recognized feature of this tissue. Bone-derived hormones that modulate whole-body homeostasis, are being discovered as for the effects on bone of novel and classic hormones produced by other tissues become known. Often, however, the data regarding these last generation bone-derived or bone-targeting hormones do not give about a clear picture of their physiological roles or concentration ranges.

Evaluation of the performance of an immunoturbidimetric HbA1c reagent applied to the Siemens ADVIA 2400 automatic analyzer.

Objectives: A new immunochemical reagent based on latex particles and antibodies against HbA1c (Axis-Shield), using Siemens ADVIA 2400 Instrument was evaluated.

Design And Methods: Intra-assay and total imprecision, interferences studies (bilirubin ~850 μmol/L, triglycerides ~16.9 mmol/L, total protein ~140 g/L, sodium cyanate ~50 mg/dL, ascorbic acid ~50 mg/dL, urea ~24.
