From Model to Practice: Testing Near‐Infrared Spectroscopy as a Bone Collagen Prescreening Tool

Archaeometry, EarlyView.
ABSTRACT Collagen is a vital archaeological material, preserving biochemical signatures that provide insights into past environments, diets, and human–animal interactions. However, diagenetic processes can lead to rapid and often inconspicuous degradation of collagen. Given the variability in collagen preservation and its significance for analyses such

Interlaboratory performance testing on EPIC v2.0 CNS tumor profiling demonstrates high reproducibility of tumor classification but reveals the need for harmonized copy number variation reporting

Brain Pathology, EarlyView.
Using the Infinium MethylationEPIC v2.0 array and Heidelberg Brain Tumor Classifier v12.8, 24 international laboratories achieved highly reproducible CNS tumor classification (97.9% correct; median β‐correlation r = 0.99), while copy number variation interpretation showed substantial interlaboratory variability, highlighting the need for harmonized CNV

Hyperlipidaemia in youth with type 1 diabetes: Are current guidelines clinically useful?

Diabetic Medicine, EarlyView.
Abstract Aims Dyslipidaemia in youth with type 1 diabetes mellitus (T1D) is emerging as an important modifiable cardiovascular risk factor. International consensus guidelines to screen this entity have evolved over time. To further evaluate this in an Australian context, we investigated adherence to such guidelines over the course of patient care ...

Interlaboratory Comparison of Radioimmunological Calcitonin Determination [PDF]

cclm, 1982
An interlaboratory study for the radioimmunological determination of calcitonin was performed within the European PTH Study Group (ESPG), to improve comparability using external quality control. Twelve laboratories determined calcitonin in 21 deep frozen samples using their respective calcitonin radioimmunoassay systems. The samples included a standard

Triple Oxygen Isotope Compositions of Isotopic Reference Waters: Implications for VSMOW‐Scale and VSMOW–SLAP‐Scale Δ′17O Calibration

Geostandards and Geoanalytical Research, EarlyView.
Key Points Triple oxygen isotope ratios of two primary (VSMOW, SLAP) and twelve secondary water isotopic reference materials were precisely measured using BrF5 fluorination‐IRMS. The measured Δ'17OVSMOW value for SLAP (34 ± 6 per meg) demonstrates that VSMOW‐SLAP normalisation ensures interlaboratory comparability, but introduces systematic offsets for

Interlaboratory comparison of magnetic thin film measurements

Journal of Research of the National Institute of Standards and Technology, 2003
A potential low magnetic moment standard reference material (SRM) was studied in an interlaboratory comparison. The mean and the standard deviation of the saturation moment m s, the remanent moment m r, and the intrinsic coercivity H c of nine samples were extracted from hysteresis-loop measurements. Samples were measured by thirteen laboratories using

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Accuracy of Factor VIII Assays for Measuring Damoctocog Alfa Pegol: A Comparative Analysis

Haemophilia, EarlyView.
ABSTRACT Introduction Accurate monitoring of treatment with modified factor VIII products remains challenging, due to known variability in assay performance across different laboratory methods and reagents. For the extended half‐life product Damoctocog alfa pegol discrepancies have been reported.
