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

Advancements in Blood Group Genotyping Technology and Clinical Applications

by

Clin Chem. 2026 Feb 18:hvag008. doi: 10.1093/clinchem/hvag008. Online ahead of print. ABSTRACT BACKGROUND: Blood group typing is essential in transfusion medicine, transplantation, and prenatal care. With the elucidation of the molecular genetics underlying blood group antigens, primarily single-nucleotide variants (SNVs), DNA-based genotyping has emerged as a powerful alternative to serological methods, enabling more accurate and … Read more

The ARRplus: a model for renin-dependent and sex-specific aldosterone cut-offs that improves screening for primary aldosteronismSybille Fuldon February 16, 2026 at 11:00 am

by

Clin Chem Lab Med. 2026 Feb 17. doi: 10.1515/cclm-2025-1670. Online ahead of print. ABSTRACT OBJECTIVES: Screening for primary aldosteronism (PA) using the aldosterone:renin ratio (ARR) has suboptimal diagnostic accuracy, particularly in females. We assessed whether accuracy could be improved using sex-specific relationships of aldosterone with renin. METHODS: Plasma aldosterone and renin were measured in 442 … Read more
