## 1 Introduction  
Chronic diseases and cancer continue to exert significant pressure on global health systems, contributing to over 70% of all deaths worldwide, according to the World Health Organization (WHO) [1]. The economic and societal costs associated with these conditions extend far beyond healthcare expenses, impacting workforce productivity, absenteeism and organizational resilience. Traditional diagnostic models, heavily reliant on centralized laboratories, often present barriers such as delays in diagnosis, limited accessibility and low participation rates, particularly among working populations who may struggle to prioritize medical appointments amid professional commitments. Since the workplace is the second most significant setting where individuals spend the most time after home, the development of diagnostic tests suitable for workplace-based screening of cancer and chronic diseases is an immediate requirement. Occupational health issues are denominated as 'employer's liabilities' in the context of regulatory compliance. Industries are compelled to keep track of employees' health status and lifestyle. In the counterpart of employees,though, no framework is available for them to monitor their health status directly without being susceptible to the employers' prejudgement and discrimination. In conjunction with cancer and chronic disease preliminary tests, focusing on the workplace and its intrusiveness and privacy issues, a tracking system neologism 'E-employment' should be introduced to provide on- and post-workplace application, along with the system overview and mechanism in tackling the concerns [2; 3]. Point-of-care testing (POCT) has emerged as a transformative approach to decentralized diagnostics, providing rapid and reliable results at or near the site of care [4; 5; 6; 7]. By minimizing logistical burdens and enabling immediate clinical decision-making, POCT offers a pragmatic solution for enhancing early detection efforts within occupational health initiatives. Awareness of health and preventive healthcare management has become a global trend since the outbreak of the COVID-19 pandemic in 2020. Since then, several routine health tests, such as COVID-19 rapid antigen tests, have been performed at an individual level, and healthy habits are being promoted by countries across the globe. Health screenings for chronic diseases such as diabetes, cardiovascular disease and cancer are becoming increasingly widespread in workplaces and communities as a part of corporate social responsibility. A variety of point-of-care (POC) and rapid testing technologies have been developed for such tests that have traditionally been performed in hospitals and clinical laboratories [8]. Conventional methodology involves sample collection and transportation to a testing center, a multi-step process to obtain analyzed results that could take anywhere from a few hours to a few weeks. Furthermore, the interpretation of test results is highly reliant on epidemiologists and laboratory technicians, irrespective of the testing platform, and well-trained professionals are needed for sample preparation and result analysis. To avoid misinterpretation of the results, secondary confirmation by a reference platform with a different methodology is often required. The emergence of alternative testing approaches, the advancements in testing technologies and the interests of various stakeholders have contributed to the development of rapid tests with higher accessibility and reliability [9]. COVID-19 rapid tests are a prime example of how testing technologies can be developed and deployed in a very short time by several stakeholders, and such innovations should also be focused on other health and wellness-related issues [10; 11; 12]. In addition, the COVID-19 pandemic catalyzed the development and widespread adoption of digital health passports--secure, mobile platforms for managing personal health information [13; 14; 15; 16].
