ABSTRACT OBJECTIVES: Bone status indices (BSIs) are increasingly used in metabolic bone disease, yet global laboratory practices remain poorly characterized. Building on recent IOF-IFCC nomenclature and ESCEO-IOF-IFCC recommendations, we conducted an international descriptive survey of BSI practices. METHODS: A cross-sectional web-based questionnaire … Read more

Clin Chem Lab Med. 2026 Aug 7. doi: 10.1515/cclm-2026-0949. Online ahead of print. ABSTRACT Integrated diagnostics is an emerging multidisciplinary model of care that integrates traditionally siloed domains, including pathology, radiology, genomics, and laboratory medicine, into a coordinated framework designed to improve diagnostic accuracy, treatment selection, and clinical outcomes. In this position statement, the EFLM … Read more

Clin Chem Lab Med. 2026 Aug 6. doi: 10.1515/cclm-2026-0428. Online ahead of print. ABSTRACT OBJECTIVES: Therapeutic drug monitoring (TDM) of meropenem is critical for optimizing clinical efficacy and minimizing toxicity. We describe the validation of an isotope dilution-liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) candidate reference measurement procedure (RMP) for the quantification of meropenem in human serum … Read more

Clin Chem Lab Med. 2026 Aug 4. doi: 10.1515/cclm-2026-0711. Online ahead of print. ABSTRACT OBJECTIVES: Limited guidance on the use and interpretation of cardiac troponin (cTn) testing in pediatric populations has restricted its broader adoption, despite the significant burden of congenital and acquired cardiac conditions in children. This survey aimed to evaluate global availability, utilization … Read more

ABSTRACT OBJECTIVES: Pregnancy involves dynamic metabolic changes that cannot be accurately interpreted using population reference intervals (RI). The aim was to develop continuous reference curves for common hematology and biochemistry laboratory analytes in pregnancy and to assess their agreement with the RIs … Read more

ABSTRACT Population screening for type 1 diabetes (T1D) using pancreatic islet autoantibodies is increasingly recognized as a promising strategy to reduce diabetic ketoacidosis and identify individuals during the presymptomatic stages of the disease. In Italy, Law 130/2023 and the implementing decree of … Read more

Clin Chem Lab Med. 2026 Jul 29. doi: 10.1515/cclm-2026-0875. Online ahead of print. ABSTRACT BACKGROUND: Patient risk management has become central to clinical laboratory quality standards, including the Clinical and Laboratory Standards Institute (CLSI) EP23 2nd edition (CLSI EP23-ED2), International Organization for Standardization (ISO) 15189:2022, ISO 22367:2026, and ISO 14971:2019. A key component of risk … Read more

Clin Chem Lab Med. 2026 Jul 29. doi: 10.1515/cclm-2026-0469. Online ahead of print. ABSTRACT OBJECTIVES: Traditional urine immunofixation electrophoresis (uIFE) is cumbersome, has limited sensitivity, and is subjectively interpreted. This is especially problematic in renal impairment where accumulation of polyclonal free light chains may pseudonormalize the serum free light chain (sFLC) ratio, compromising its reliability … Read more
