Introduction: To perform simulation studies on patient-based real-time quality control (PBRTQC) for aspartate aminotransferase (AST), iron (Fe), potassium (K), and thyrotropin (thyroid stimulating hormone, TSH) analytes, focusing on optimizing systematic error detection while minimizing data loss.

Methods: Clinical laboratory data for the four analytes were analyzed using various truncation methods. Among these methods, truncation limits corresponding to fixed percentiles (e.

Introduction: Gestational diabetes mellitus (GDM) is defined as glucose intolerance during pregnancy. We aimed to investigate the potential effects of betatrophin and ApoC2 in GDM, focusing on their roles in LPL (lipoprotein lipase) regulation and their relationship with hPL to elucidate the possible impact of hPL on lipid metabolism and its potential contribution to the development of GDM.

Methods: Thirty pregnant women with normal glucose tolerance and 29 with gestational diabetes mellitus (diagnosed by 75g OGTT between 24 and 28 weeks) were included in the study.

Article Synopsis
  • * Results indicated that certain tests, particularly cardiac biomarkers, blood gases, and specific drug levels, were perceived to pose a higher risk for patient harm due to erroneous results.
  • * There was strong agreement (91%) between medical biochemists and clinicians regarding the severity scores, highlighting the tests that require focused quality improvement efforts.

Article Synopsis
  • The study investigates a new method for establishing population-based reference intervals (popRIs) using biological variation (BV) data rather than traditional single measurement results from 120 reference individuals.
  • The proposed model defines the population set point (PSP) using a combination of BV and analytical variation, calculating RI limits by analyzing data from 143 individuals across 48 clinical measures with varying sample sizes.
  • Results indicate that the BV-based popRIs largely align with conventional intervals, needing fewer reference individuals while still achieving acceptable coverage of the population, suggesting easier implementation if reliable BV data is accessible.

Artificial intelligence (AI) and machine learning (ML) are becoming vital in laboratory medicine and the broader context of healthcare. In this review article, we summarized the development of ML models and how they contribute to clinical laboratory workflow and improve patient outcomes. The process of ML model development involves data collection, data cleansing, feature engineering, model development, and optimization.
