World Health Organization
In response to the recent urgent need for the fast development of health products in the treatment of COVID-19, the World Health Organization (WHO) are in the process of developing a Good Manufacturing Practice (GMP) document to address the manufacturing of developmental batches, pilot batches and the sequential stability data that is submitted in product applications (dossiers) for marketing authorization and the prequalification of medical products.
There are currently no regulatory guidelines which address this matter, although the data collected from these batches influences the following aspects of the product:
- Stability
- Process validation
- Analytical method development and validation

ZES Director Steps Down From The RCT After Over 6 Years
The Register of Clinical Technologists (the RCT) – formerly the Voluntary Register of Clinical Technologists – was formed in 2000 with the aim of protecting the public by advocating statutory, professional regulation for Clinical Technologists. The register now holds the details of over 2000 healthcare professionals who have achieved the standards set out by the RCT through education or equivalence. They abide by a regularly-reviewed Code of Professional Conduct and take part in continuing professional development (CPD) to maintain their professional status for the protection of the public at all times.
The Management Board are responsible for all aspects of the management of the register including overseeing the assessing and approving of applications to join the RCT. They are also responsible for reviewing and updating the criteria for membership of the RCT as well as all processes and documentation used. The RCT Management Board are supported by an administrative team from the Institute of Physics and Engineering in Medicine (IPEM) office.
The RCT Management Board actively promote the RCT to government, the Department of Health, government agencies, the Health and Care Professions Council, other professional bodies, educational establishments and the medical device industry.
Iain Threlkeld, Registrar explains
'Dave and I joined the RCT management panel, as it was then called, back in 2013 when IHEEM replaced the IET as the third professional body administering the RCT, and is therefore one of the longest serving of our current members.
I would like to thank Dave on behalf of everyone on the RCT management board for all his help and support over the years and would like to wish him all the best for his future.'
David adds
'I've been the IHEEM representative on the RCT management board for over 6 years and in that time I've contributed enthusiastically to the register's activities in a small but essential way, primarily being the improvement of safety standards for patients, by helping to ensure and raising the standards within the Medical Device maintenance activity, carried out in hospitals.
I would like to thank the other members of the Management Board, both previous and current, for their contribution and their professionalism throughout my tenure. I would like to sincerely wish the RCT every success in the future.'
