Towards harmonization of autoantibody detection in relation to paraneoplastic neurological syndromes (PNS): a European Survey on laboratory practicesMatthijs Oyaerton October 6, 2025 at 10:00 am

by

Clin Chem Lab Med. 2025 Oct 7. doi: 10.1515/cclm-2025-1030. Online ahead of print. ABSTRACT OBJECTIVES: Detection of paraneoplastic anti-neuronal antibodies (PNS autoantibodies) aids in diagnosing the particular syndrome and guides the search for an underlying tumor. To identify opportunities for harmonization that could enhance diagnostic value, we assessed variability in autoimmune serological testing for PNS … Read more

Estimated waste generation from 1 million basic metabolic panels: a multisite U.S. studySeema Khattri Bhandarion October 6, 2025 at 10:00 am

by

Clin Chem Lab Med. 2025 Oct 7. doi: 10.1515/cclm-2025-1162. Online ahead of print. ABSTRACT OBJECTIVES: Clinical laboratory operations consume large amounts of electricity and water and generate considerable quantities of solid waste. In this study, we quantified and compared the estimated solid waste produced from performing one million basic metabolic panels (BMPs) across five major … Read more

Serum neuron-specific enolase – reference interval in Danish children and the impact of preanalytical factorsJacob Rudjord Therkildsenon October 2, 2025 at 10:00 am

by

Clin Chem Lab Med. 2025 Oct 3. doi: 10.1515/cclm-2025-0582. Online ahead of print. ABSTRACT OBJECTIVES: Neuron-specific enolase (NSE) is a clinically relevant biomarker used in the assessment of neuronal damage and in the diagnosis and monitoring of certain cancers. Despite its diagnostic importance, paediatric-specific reference intervals (RIs) for NSE are currently lacking. This study aimed … Read more

Post-analytical practices in clinical mass spectrometry laboratories: an international survey across 57 countriesJenny Yeuk-Ki Chengon October 1, 2025 at 10:00 am

by

Clin Chem Lab Med. 2025 Oct 2. doi: 10.1515/cclm-2025-1136. Online ahead of print. ABSTRACT OBJECTIVES: Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is increasingly used in clinical laboratories due to its high analytical specificity and multiplexing capabilities. While the pre-analytical and analytical phases have seen significant advances in automation, the post-analytical phase remains a bottleneck with limited … Read more

Serum N-glycans as independent predictors of the incidence of type 2 diabetes: a prospective investigation in the AEGIS cohortIago Carballoon September 30, 2025 at 10:00 am

by

Clin Chem Lab Med. 2025 Jun 24;63(11):2330-2340. doi: 10.1515/cclm-2025-0045. Print 2025 Oct 27. ABSTRACT OBJECTIVES: Glycosylation is a tightly controlled co-translational and post-translational enzymatic modification. Total N-glycome profiling in blood serum/plasma provides information on the most common serum/plasma glycosylation. Total plasma N-glycome from various population samples displayed predictive ability for type 2 diabetes incidence in … Read more
