Evaluation of Sensitive Analytes to Hemolysis Interference on an Automated Chemistry Analyzer.

Background: Hemolysis is a common reason for specimen rejection in the laboratory. Our experience suggested that hemolysis (H) flag limits are too strict for some analytes leading to unnecessary specimen rejections. This study summarizes H flags for commonly rejected analytes on the Beckman Coulter DxC 700 AU analyzer.

A rare occurrence of Anaplasma-associated peritonitis.

Anaplasmosis or human granulocytic anaplasmosis is a tick-borne illness caused by the bacteria, Anaplasma phagocytophilum, resulting from an infected tick bite. Examination of a blood smear within the first week of exposure may show microcolonies of anaplasmae (morulae) in the cytoplasm of neutrophils that are highly suggestive of anaplasmosis but not definitive. We present the first case describing Anaplasma-related peritonitis and morulae in peritoneal fluid granulocytes in a peritoneal dialysis patient who developed anaplasmosis.

Comparison of antibody response durability of mRNA-1273, BNT162b2, and Ad26.COV2.S SARS-CoV-2 vaccines in healthcare workers.

Objectives: There are limited comparative immunologic durability data post COVID-19 vaccinations.

Methods: Approximately 8.4 months after primary COVID-19 vaccination, 647 healthcare workers completed surveys about COVID-19 vaccinations/infections and blood draws.

Challenging the Good Life: An Institutional Theoretic Investigation of Consumers' Transformational Process Toward Sustainable Living.

In pursuit of sustainable living, ethics researchers as well as consumers themselves have challenged the status quo of consumption as an institution. Fueled by global economic, environmental, and societal concerns, responsible consumption has become an integral part of the sustainability and consumption ethics literature. One movement toward sustainability consists of confining living space into a smaller ecological footprint.

Evaluation of the Beckman Coulter DxC 700 AU chemistry analyzer.

Objectives: We evaluated and defined the analytical performance of the Beckman Coulter DxC 700 AU analyzer compared to the Siemens Dimension Vista 500 analyzer.

Design: and Methods: Performance characteristics included intra and inter-run precision, linearity/analytical measurement range, method correlation, and reference range verification. A total of 53 assays including 11 critical care, 19 general chemistries, 11 proteins, 10 urines, and 2 CSF analytes were tested.
