Flow cytometry, cytology and histology in the diagnosis of ocular hematologic neoplasms: a 15-year monocentric experience with a focus on ocular lymphomasAlessandra Faldaon December 30, 2025 at 11:00 am

by

Clin Chem Lab Med. 2025 Oct 9;64(2):489-504. doi: 10.1515/cclm-2025-0216. Print 2026 Jan 29. ABSTRACT OBJECTIVES: Ocular lymphomas are rare diseases that occur in ocular adnexa or specific intraocular regions. Although histology remains the gold standard, cytology and flow cytometry (FCM) are fundamental, mainly when a biopsy sampling is technically demanding. This study evaluated the effectiveness … Read more

ABSTRACT OBJECTIVES: Neurofilament light chain (NfL) is a biomarker of neuroaxonal damage in various neurological conditions, including multiple sclerosis (MS). With new analytical platforms entering the market, standardization of serum NfL (sNfL) measurement is essential. This study compared sNfL levels across three … Read more

Development and validation of a candidate reference measurement procedure for free triiodothyronine and free thyroxine in human serum using equilibrium dialysis isotope-dilution liquid chromatography-tandem mass spectrometryMin Zhanon December 17, 2025 at 11:00 am

by

Clin Chem Lab Med. 2025 Dec 18. doi: 10.1515/cclm-2025-0874. Online ahead of print. ABSTRACT OBJECTIVES: Free triiodothyronine (FT3) and free thyroxine (FT4) are important diagnostic markers for assessing thyroid function. However, their accurate quantification remains challenging due to low serum concentrations. Significant variability exists among current assay methods for measuring FT3 and FT4. This study … Read more
