Homocitrulline and 3-year mortality in older hospitalised adults: an exploratory studyPeter Noujaimon July 1, 2026 at 10:00 am

by

Clin Chem Lab Med. 2026 Jul 2. doi: 10.1515/cclm-2026-0173. Online ahead of print. ABSTRACT OBJECTIVES: Reliable biomarkers may allow early risk stratification for mortality in older adults. Post-translational modification-derived products (PTMDPs), such as homocitrulline, and the tissue accumulation of advanced glycation end products (AGEs), measured by skin autofluorescence, have been suggested as potential biomarkers of … Read more

Analysis of albumin-to-creatinine ratio on automated analysers using a microsampling card (Capitainer DIP70 card) for the collection of urineJohan Olaussonon June 29, 2026 at 10:00 am

by

Clin Chem Lab Med. 2026 Jun 30. doi: 10.1515/cclm-2026-0034. Online ahead of print. ABSTRACT OBJECTIVES: Albuminuria is a key biomarker of kidney damage, yet preanalytical challenges with conventional liquid urine testing, limiting its utility for decentralized and large-scale screening. This study evaluated the analytical performance of a novel dried urine spot (DUS) device, for measuring … Read more

The effect of Sebia’s CZE IFCC-converted results on carbohydrate-deficient transferrin (CDT) interpretation in driver’s license assessmentsNathan Debunneon June 25, 2026 at 10:00 am

by

Clin Chem Lab Med. 2026 Jun 26. doi: 10.1515/cclm-2026-0346. Online ahead of print. ABSTRACT OBJECTIVES: Carbohydrate-deficient transferrin (CDT) is a specific biomarker for chronic excessive alcohol consumption. The IFCC Working Group on CDT Standardization recommends 2-sialo-transferrin (2-sialo-Tf) as the sole measurand, with a decision threshold of 2.0 % CDTIFCC using HPLC. This study evaluates the … Read more

by

Clin Chem Lab Med. 2026 Jun 26. doi: 10.1515/cclm-2026-0464. Online ahead of print. ABSTRACT OBJECTIVES: Accurate estimation of glomerular filtration rate (eGFR) is necessary for early detection and staging of chronic kidney disease (CKD), risk stratification, and guiding therapies that prevent complications and progression to advanced CKD. This study aimed to evaluate the performance of … Read more

New insights in primary aldosteronism diagnosis: a prospective multicenter studyKaijuan Wangon June 25, 2026 at 10:00 am

by

Clin Chem Lab Med. 2026 Jun 26. doi: 10.1515/cclm-2026-0579. Online ahead of print. ABSTRACT OBJECTIVES: The high variability in screening and confirmatory cut-off values for primary aldosteronism (PA) largely reflects the insufficient standardization of current analytical methods. Competitive and sandwich immunoassays show variable correlation with the reference liquid chromatography-tandem mass spectrometry (LC-MS/MS) technique. This prospective … Read more
