Blood‐Based Biomarkers in Alzheimer's Disease: Advances in Detection Technologies and Clinical Applications [PDF]

AGING MEDICINE, EarlyView.
Blood‐based biomarkers are emerging as accessible tools for Alzheimer's disease screening, diagnosis, risk stratification, and longitudinal monitoring. This review summarizes major biomarkers, including Aβ42/Aβ40, phosphorylated tau species, NfL, GFAP, genetic risk markers, and exploratory inflammatory, synaptic, and proteomic candidates.

Sugammadex interference with serum progesterone measurement: an in‐vitro study [PDF]

Anaesthesia, Volume 81, Issue 11, Page 1489-1496, November 2026.
Summary Introduction Sugammadex may interfere with serum progesterone immunoassays, potentially rendering measured concentrations and resulting recommendations unreliable. Methods We investigated the effect of a range of sugammadex concentrations on serum progesterone concentrations in samples from pre‐menopausal female volunteers.

Serum Neurofilament Light Chain and GFAP in Amyotrophic Lateral Sclerosis on a Commercial ECLIA Platform [PDF]

Muscle &Nerve, Volume 74, Issue 5, Page 1398-1405, November 2026.
ABSTRACT Introduction/Aims In amyotrophic lateral sclerosis (ALS), SIMOA‐based studies show that baseline serum neurofilament light chain (NfL) predicts the revised ALS Functional Rating Scale (ALSFRS‐R) decline rate and survival. The Roche Elecsys electrochemiluminescence immunoassay (ECLIA) reports values approximately six‐fold lower; cross‐platform ...
