Clinical laboratories face ethical challenges on a daily basis. The ethics training provided for clinical laboratory staff is variable, with some receiving no training. We aimed to explore the perceived benefits of ethics education for laboratory professionals. Ethics training was provided to approximately 60 laboratory professionals in a UK not-for-profit blood cancer organisation, with group discussions incorporated into the session. The session covered dominant ethical theories and principles, the defining moments in medical research ethics and the ethical aspects of laboratory practices. At the end of the session a short optional paper survey was distributed to the participants to obtain feedback on the training. The feedback was anonymous and thematically coded. Attendees reported to be more aware of the existence and importance of ‘everyday’ ethics in their workplace. Responses also showed that the training session had provided participants with an opportunity for ethical reflection in themselves and in discussion with their colleagues. Despite clinical laboratory professionals being faced with ethical challenges daily, there is comparatively little ethics education provided. Ethics training is believed to improve the ethical attitude of laboratory staff and help them when making decisions in their work. We have shown that ethics education is important for laboratory professionals to develop and retain ethical awareness, and ethical reflection. By gaining insight into the ethical aspects of their practices, laboratory professionals can apply this understanding when faced with making challenging decisions in their workplace, in order to act in the best interests of their patients.
