Comprehensive Evaluation of Commercial Antibodies for High Sensitivity Detection of EPO‐Doping on Western Blots

Drug Testing and Analysis, EarlyView.
A large‐scale evaluation of 164 commercially available anti‐human EPO antibodies was conducted to identify an alternative to clone AE7A5 anti‐EPO antibody used in doping control for the detection of erythropoiesis‐stimulating agents (ERAs) on Western blots.

Simultaneous Detection of Steroid Esters and Multi‐Class Substances in Dried Blood Spots by LC‐HRMS/MS From a Single Spot for Human Doping Control

Drug Testing and Analysis, EarlyView.
A validated LC‐HRMS/MS method enabled, for the first time, the comprehensive detection of steroid esters and multi‐class menu substances from a single dried blood spot. Following extraction, the resulting extract is split into two aliquots, reducing sample consumption and simplifying the analytical workflow.

Estimating Illicit Stimulant Drug Consumption in Luxembourg Using Wastewater‐Based Epidemiology

Drug Testing and Analysis, EarlyView.
Wastewater‐based epidemiology provided nationwide estimates of illicit stimulant consumption in Luxembourg, revealing higher urban use, weekend increases in cocaine and MDMA, and cocaine as the dominant stimulant. The approach offers an objective complement to conventional drug surveillance for informing public health and policy.

A Single‐Aliquot Strategy for Simultaneous Carbon Isotope Confirmation of 6‐Oxo‐Androstenedione and Testosterone Misuse in Doping Control

Drug Testing and Analysis, EarlyView.
This method enables simultaneous carbon isotope confirmation of 6‐oxo‐androstenedione and testosterone markers from a single urine aliquot, using bench‐top extraction, two preparative HPLC steps with intermediate acetylation, and GC/C/IRMS analysis. It was fully validated according to WADA requirements, and real samples demonstrated its fitness for ...

Potential Contamination Cases in Anti‐Doping: Experiences and Practices of 33 Anti‐Doping Organisations

Drug Testing and Analysis, EarlyView.
Across 33 Anti‐Doping Organisations (ADOs), 85% reported experiencing at least one contamination‐claim case in 2024–2025, but only 36% operate a standardised process for handling such claims. Dietary supplements were the leading alleged contamination source (76% of ADOs), followed by food (42%) and pharmaceutical products, intimate contact, and other ...

Evidence for the Effectiveness of the Performance Passport Within an Intelligence‐Based Weightlifting Anti‐Doping Programme

Drug Testing and Analysis, EarlyView.
Anti‐doping programmes require efficient testing, as biological testing is costly; the Athlete Performance Passport (APP) uses performance data to identify at‐risk athletes alongside APMU and ABP methods. Since the introduction of the steriodal passport in 2014, the APP outperformed APMU (17%) and ABP steroidal profiles (10%) with 30% detection ...

Population‐Stratified Distributions of Post‐Mortem Blood Drug Concentrations: An Epidemiological Framework for Contextual Interpretation

Drug Testing and Analysis, EarlyView.
Post‐mortem blood drug concentrations exhibit substantial overlap between deaths in which a drug was implicated and those in which it was not. Analysis of over 58,000 NPSUM cases demonstrates that demographic stratification does not resolve this uncertainty, reinforcing the need for contextual, evidence‐based interpretation rather than concentration ...

Intra‐Individual Variability of Blood and Urinary Steroid Markers and the Response to Codeine Intake in Healthy Men and Women

Drug Testing and Analysis, EarlyView.
Short‐term codeine administration (1–3 days) caused individual alterations in Athlete Biological Passport steroid markers, including elevated urinary T/E ratios and decreased serum testosterone concentrations below individual thresholds, despite no significant changes at the group level.
