Impact of intervention on preanalytical errors assessed by six sigma and Pareto’s principle [PDF]

Al Ameen Journal of Medical Sciences
Introduction: Preanalytical steps are the major sources of error in the clinical laboratory. The analytical errors can be corrected by quality control procedures but there is a need for stringent quality checks in the preanalytical area as these ...

Preanalytical variables affect predictive immunohistochemical biomarker testing in non–small cell lung carcinoma cytology specimens

Cancer Cytopathology, Volume 134, Issue 11, November 2026.
Abstract Background Several therapeutic targets for non–small cell lung carcinoma (NSCLC) rely on protein expression by immunohistochemistry (IHC). Most biomarkers are validated on formalin‐fixed, paraffin‐embedded (FFPE) tissue; however, cytologic specimens, including cell blocks (CBs), that are subject to preanalytical variables are increasingly used.

Toward a digital urinary biopsy for early risk stratification in diabetic kidney disease: Anchoring shed cells, vesicles, and cell‐free DNA to spatial kidney cell states

Clinical and Translational Medicine, Volume 16, Issue 11, November 2026.
In diabetic kidney disease, one urine specimen carries shed cells, extracellular vesicles and cell‐free DNA released along the whole nephron. Reading all three against spatial kidney atlases is proposed as a testable route to cell‐resolved, non‐invasive risk stratification, and the clinical outputs shown are not yet demonstrated.

Preanalytical requirements of urinalysis [PDF]

, 2014
Urine may be a waste product, but it contains an enormous amount of information. Well-standardized procedures for collection, transport, sample preparation and analysis should become the basis of an effective diagnostic strategy for urinalysis.

Performance Evaluation of Dry Chemical Colorimetry for Plasma Ammonia Detection on the VITROS 350 Chemistry System

Journal of Clinical Laboratory Analysis, Volume 40, Issue 21, November 2026.
This study comprehensively validates the analytical performance of the VITROS dry chemical colorimetric assay for plasma ammonia on the VITROS 350 system. The assay shows excellent precision, accuracy, and linearity throughout the analytical range. It is highly resistant to common interferents such as bilirubin, lipids, and vitamin K1.

HIL Interferences on Three Hemostasis Analyzers and Contribution of a Preanalytical Module for Routine Coagulation Assays.

, 2016
Preanalytical issues are a major part of routine coagulation laboratory errors. Automation in detection of preanalytical problems, including hemolysis, icterus and lipemia (HIL), improper tube fill volume, and undue clotting, has recently been ...

Liquid Biopsy: Past, Present, and Future

MedComm, Volume 7, Issue 11, November 2026.
Liquid biopsy has expanded from cancer genotyping to a broader strategy for probing both oncologic and nononcologic conditions through circulating analytes and multilayer molecular readouts. This review traces the field's past, present, and future—summarizing where liquid biopsy is most actionable today, why performance varies across contexts, and ...

Severe pseudohyperkalaemia in a cat with profound creatine kinase elevation after suspected trauma

Veterinary Record Case Reports, Volume 14, Issue 4, November 2026.
Abstract A 5‐year‐old, neutered, male domestic shorthair cat (5.0 kg) was presented for acute lethargy and inappetence after a suspected traumatic event. The cat was painful over the caudal abdomen and lumbar region, with superficial abrasions.
