Pruebas de drogas en el lugar de trabajo - son los métodos legalmente defendible? Una encuesta de expertos, árbitros
JAMA
|July 24, 1987
Resumen
La prueba de drogas del empleador mediante análisis de orina tiene implicaciones legales. Este estudio encuestó a expertos y árbitros para evaluar la defensa legal de los métodos analíticos, encontrando una variación significativa y la necesidad de una mejor orientación para los directores médicos.
Área de la Ciencia:
- Toxicología Forense.
- Salud ocupacional y salud en el trabajo.
- La medicina legal es la medicina legal.
Sus antecedentes:
- Las pruebas de drogas en el lugar de trabajo a través del análisis de orina son comunes, con importantes consecuencias profesionales y legales para los empleados.
- La selección de métodos analíticos y laboratorios apropiados es crucial para la defensa legal de los resultados de las pruebas de drogas.
- Los directores médicos de la empresa a menudo carecen de datos suficientes para elegir laboratorios y métodos de manera efectiva.
Objetivo del estudio:
- Evaluar la defensa legal de varios métodos analíticos utilizados en el análisis de orina en el lugar de trabajo.
- Proporcionar a los directores médicos de la empresa datos para informar las decisiones sobre la selección de laboratorios y métodos de análisis de orina.
Principales métodos:
- Se realizó una encuesta entre expertos técnicos, laboratorios comerciales de pruebas de drogas y árbitros.
- Los participantes calificaron la defensa legal de los diferentes métodos analíticos utilizados en el análisis de orina.
- Se evaluó la experiencia de los árbitros con casos de consumo de drogas y su comprensión del análisis de orina.
Principales resultados:
- Los expertos técnicos informaron diferencias sustanciales en la defensa legal percibida de varios métodos analíticos.
- Los árbitros, a pesar de su amplia experiencia, no pudieron distinguir de manera confiable la defensabilidad legal de diferentes métodos analíticos.
- Las prácticas comerciales de laboratorio en las pruebas de análisis de orina muestran una considerable variabilidad.
Conclusiones:
- Hay una notable falta de consenso y claridad con respecto a la defensa legal de los métodos de análisis de orina.
- La incapacidad de los árbitros para diferenciar la defensabilidad del método pone de relieve una brecha en la comprensión o la estandarización.
- Se necesita información mejorada para guiar a los directores médicos en la selección de servicios de análisis de orina confiables y legalmente sólidos.

02:07Blind Procedures
Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which child was...
01:25Drug Regulation
Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...
01:15Data Validation
Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
Key parameters for method validation include:

01:02Sample Handling
Transportation of samples from the collection point to the laboratory, as well as storage and preservation techniques, are crucial for maintaining sample integrity and ensuring accurate and reliable test results.
Samples should be transported carefully from collection points to the laboratory. They should be properly sealed and clearly labeled to prevent cross-contamination. To preserve the sample integrity, optimal temperature conditions during transport are essential. This could involve using...

01:13Bioequivalence studies: Biowaivers
In certain scenarios, in vitro dissolution tests can replace in vivo bioequivalence studies. This is particularly true when a drug product, though available in varying strengths, maintains proportional similarity in its active and inactive ingredients. In such cases, the need for in vivo bioequivalence studies for lower strength variants may be waived, provided dissolution tests and in vivo studies on the highest strength yield satisfactory results.Bioequivalence can be indicated through...
01:23Toxicity Testing in Animals
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
