Inborn errors of metabolism (IEM) are a group of genetically derived diseases that are individually rare but collectively common and can be very severe. While high-income countries usually employ modern scientific technologies like tandem mass spectrometry for IEM investigation, these disorders are, in contrast, only rarely screened for in developing countries due to misconceptions that the required facilities are beyond the reach of these countries. This paper attempts to educate scientists and clinicians in developing countries on low-technology IEM screening methods that only require moderate facilities. Although a definitive diagnosis of IEM may require specialised laboratory investigations and attendant interpretation, in most cases, the basic facilities available in the average clinical chemistry laboratory in developing countries can allow the early detection of IEM. This early detection would facilitate critical early decision making, thus leading to better management, optimised treatment, and reduced morbidity and or mortality of IEM in these resource-limited countries. With this approach, a few referral centres for confirmatory investigation, comparable to those existing in developed countries, could be established. This can be integrated into creative health education for healthcare professionals and families who have individuals with IEM.What this study adds: IEMs are important enough that every country, developed or developing, should have screening plans and basic laboratory facilities that are adequate for initial IEM diagnosis. No country should therefore give up on testing for IEMs on the excuse of a paucity of advanced facilities.

Laboratories generate various forms of wastes which contribute to a complex network of profound and multifaceted environmental challenges and associated public health issues if not properly managed.Traditional laboratory practices particularly in developing countries, often lead to excessive waste generation, chemical contamination and resource depletion, coupled with inefficient waste management which poses risks to both ecosystem and public health. As the environmental impact of laboratory waste escalates, the need for effective waste management becomes increasingly important and urgent for safeguarding environmental health. This review examines the impact of laboratory waste management practices on environmental health and explores sustainable laboratory medicine as a mitigating response. Sustainable laboratory medicine adopts practices such as green laboratory principles involving waste minimization, resource conservation, the use of eco-friendly materials as well as energy-efficient protocols and innovative waste segregation and treatment technologies. This approach complies with regulatory standards as well as emphasizes proactive orientation towards environmental stewardship, operational efficiency and innovation while maintaining scientific integrity. Sustainable laboratory medicine appears to be a crucial framework that mitigates the environmental health impacts associated with laboratory-derived waste. This review advocates for a paradigm shift towards sustainable laboratory operations and emphasizes the need for comprehensive training, institutional commitment, and regulatory support.
