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

Interlaboratory comparison of two homemade pencil type ionization chambers

Brazilian Journal of Radiation Sciences
Computed tomography (CT) is a diagnostic exam responsible for the highest dose values received by the patients during the procedure. Over the years, this kind of equipment has been improved to ensure that the patients do not receive unnecessary doses ...

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 ...

Analysis of interlaboratory comparisons affected by correlations of the reference standards and drift of the travelling standards

, 2011
The paper describes a method for analysing interlaboratory comparison results among accredited laboratories. Interlaboratory comparisons are used in order to achieve or to maintain the accreditation following the ISO/IEC 17025 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

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

UK recommendations for Ki‐67 immunohistochemical staining and interpretation in breast cancer

Histopathology, EarlyView.
Where possible, a validated digital imaging system should be utilized. If this is not available, then intermediate scores (5%–30%) should be thoroughly assessed using the Ki‐67 International Working Group guidance. Difficult cases should be double scored.
