Clin Chem. 2025 Jun 16:hvaf070. doi: 10.1093/clinchem/hvaf070. Online ahead of print. ABSTRACT BACKGROUND: Cell-free DNA (cfDNA) is a promising biomarker and carries information about physiological and pathological states. Nucleosome and transcription factor footprints have been extensively studied based on double-stranded cfDNA sequencing; however, protein-DNA interaction footprints in single-stranded cfDNA fragments remain undercharacterized. METHODS: We used … Read more
Clin Chem Lab Med. 2025 Jun 16. doi: 10.1515/cclm-2025-0076. Online ahead of print. ABSTRACT OBJECTIVES: Heavy Metals (HMs) concentrations vary with living environments, diet, and personal habits. This study aims to establish health-related reference intervals (RIs) for selected HMs in healthy, non-occupationally exposed young adults living in an urban environment. METHODS: The Uni4Me study enrolled … Read more

ABSTRACT BACKGROUND: For 20 years, the United States has experienced a progressive rise in syphilis cases, increasing to >209 000 cases in 2023. The current case rate of 62.5 per 100 000 persons represents a 30-fold increase since 2000-2001, when a concerted national effort … Read more

ABSTRACT BACKGROUND: The generalizability and applicability of circulating tumor DNA (ctDNA) KRAS mutations in patients with pancreatic adenocarcinoma (PAC) remain elusive. We aimed to propose a cut-off value of mutant KRAS (mKRAS) concentration in ctDNA and validate its clinical utility. METHODS: This prospective, multicenter … Read more
Clin Chem. 2025 Jun 10:hvaf068. doi: 10.1093/clinchem/hvaf068. Online ahead of print. ABSTRACT BACKGROUND: Cardiac troponin (cTn) levels exceeding the 99th percentile upper reference limit and a rise/fall pattern are key for diagnosing myocardial injury and infarction. Macrotroponins, formed by patient anti-cTn antibodies targeting cTn, can cause persistently elevated cTn levels without ongoing myocardial injury. The … Read more
Clin Chem Lab Med. 2025 Jun 9. doi: 10.1515/cclm-2025-0433. Online ahead of print. ABSTRACT The sweat test is used as a biological marker of cystic fibrosis transmembrane conductance regulator (CFTR) dysfunction, but there is growing recognition that sweat chloride concentrations of people with cystic fibrosis (CF) can overlap with those without CF. There are also … Read more
Clin Chem. 2025 Jun 4:hvaf063. doi: 10.1093/clinchem/hvaf063. Online ahead of print. ABSTRACT BACKGROUND: The consequences for health outcomes of the discordance in cystatin C-based (eGFRcys) and creatinine-based (eGFRcr) estimated glomerular filtration rates are gaining attention. However, the association of discordance with all-cause mortality in the general population has not been explored. METHODS: A total of … Read more
