Clin Chem Lab Med. 2026 Mar 3. doi: 10.1515/cclm-2026-0083. Online ahead of print. ABSTRACT OBJECTIVES: We evaluated the diagnostic performance of the Atellica HEMA 580 hematology analyzer for complete blood count (CBC) parameters compared with the ADVIA 2120i and assessed its capability to flag abnormal cells, and determined optimal cut-offs for immature myeloid cell detection. … Read more

Machine learning-based integration of antiphospholipid antibodies for predicting pregnancy outcomes in patients with recurrent spontaneous abortion: a multicenter prospective studyXinli Jiangon March 1, 2026 at 11:00 am

by

Clin Chem Lab Med. 2026 Mar 2. doi: 10.1515/cclm-2026-0088. Online ahead of print. ABSTRACT OBJECTIVES: Antiphospholipid antibodies (aPLs) are closely associated with recurrent spontaneous abortion (RSA) and adverse pregnancy outcomes (POs). Non-criteria aPLs may aid in diagnosing seronegative aPL-related RSA, but their limited performance often leads to missed or delayed diagnosis. This study aimed to … Read more

Urinary aldosterone and tetrahydroaldosterone by LC-MS/MS with enzymatic hydrolysis: validation and age-stratified reference intervalsIrene Wijbenga-van der Kooion March 1, 2026 at 11:00 am

by

Clin Chem Lab Med. 2026 Mar 2. doi: 10.1515/cclm-2025-1679. Online ahead of print. ABSTRACT OBJECTIVES: Primary aldosteronism (PA) is a common cause of secondary hypertension. To address the specificity limits of immunoassays, we developed and validated an LC-MS/MS method for urinary aldosterone and tetrahydroaldosterone and established method-matched reference intervals for excretion in 24 h urine. … Read more

T-cell receptor beta constant 1 flow cytometry for diagnosing clonality in mature T-cell neoplasms: a systematic review and meta-analysis of diagnostic accuracyPablo Adrian Biaggionion February 19, 2026 at 11:00 am

by

Clin Chem Lab Med. 2026 Feb 20. doi: 10.1515/cclm-2025-1376. Online ahead of print. ABSTRACT INTRODUCTION: Accurate assessment of T-cell clonality is key for diagnosing mature T-cell neoplasms. TRBC1-based flow cytometry provides a rapid, robust, and cost-efficient approach. This systematic review and meta-analysis assessed the diagnostic accuracy of TRBC1 flow cytometry (TRBC1-FC) for detecting T-cell clonality … Read more

Stability of different biochemical parameters in pooled left-over sera stored for 14 days after pooling either at room temperature or at 2-10 °CMaja Zabelon February 18, 2026 at 11:00 am

by

Clin Chem Lab Med. 2026 Feb 5. doi: 10.1515/cclm-2025-1693. Online ahead of print. ABSTRACT OBJECTIVES: This stability study aimed to evaluate the stability of 48 biochemical analytes in pooled serum samples derived from leftover sera over 14 days at room temperature (RT) and at 2-10 °C, and to assess the consistency of storage effects across … Read more
