Global Adoption of High-Sensitivity Cardiac Troponins and the Universal Definition of Myocardial Infarction [Evidence-Based Medicine and Test Utilization]
CONCLUSIONS: There has been global progress toward the recommendations of the UDMI, particularly in the use of the 99th percentile diagnostic threshold and serial sampling. However, high-sensitivity assays are still used by a minority of sites, and sex-specific thresholds by even fewer. Additional efforts are required to improve risk stratification and diagnosis of patients with myocardial infarction. (Source: Clinical Chemistry)

Trueness Evaluation and Verification of Interassay Agreement of 11 Serum IgA Measuring Systems: Implications for Medical Decisions [Pediatric Clinical Chemistry]
CONCLUSIONS: Although the harmonization among most commercially available IgA MSs is good, the implementation of traceability to higher order references is inadequate, especially at concentrations ≤0.7 g/L. This analytical background information needs to be considered carefully when defining traceable reference intervals in the pediatric population. (Source: Clinical Chemistry)

Predicting Acute Myocardial Infarction with a Single Blood Draw [Proteomics and Protein Markers]
CONCLUSIONS: Serial sampling does not seem necessary for predicting AMI and concurrent decision-making in about 10% of patients, as it only marginally increases the PPV for AMI and not in a statistically or clinically significant way.

Quality Monitoring of a FIT-Based Colorectal Cancer Screening Program [General Clinical Chemistry]
CONCLUSIONS: Variations were observed in positivity and detection rates between collection devices and reagents, but there was no detected variation in PPV. Although the overall population effect of these variations on the screened population is expected to be modest, there is room for improvement. (Source: Clinical Chemistry)

Implications of Monoclonal Antibody Therapeutics Use for Clinical Laboratory Testing [Reviews]
BACKGROUND: Monoclonal antibody therapeutics (MATs) represent a rapidly expanding class of biological drugs used to treat a variety of diseases. The widespread use of MATs increasingly affects clinical laboratory medicine. CONTENT: This review provides an overview of MATs currently approved for clinical use in the US, starting from basic biology of antibodies to the engineering, pharmacokinetic and pharmacodynamic properties, nomenclature, and production of MATs. Immunogenicity and the production of antidrug antibodies (ADAs) play a major role in loss of therapeutic response and the development of treatment failure to cer...

Next-Generation Sequencing for Biodefense: Biothreat Detection, Forensics, and the Clinic [Reviews]
BACKGROUND: Next-generation sequencing (NGS) is revolutionizing a variety of molecular biology fields including bioforensics, biosurveillance, and infectious disease diagnostics. For pathogen detection, the ability to sequence all nucleic acids in a sample allows near limitless multiplexability, free from a priori knowledge regarding an etiologic agent as is typically required for targeted molecular assays such as real-time PCR. Furthermore, sequencing capabilities can generate in depth genomic information, allowing detailed molecular epidemiological studies and bioforensics analysis, which is critical for source agent ide...
