HPCSA Pathology Registrar Research Requirements

All HPCSA pathology registrars must complete a research project during their 4-year specialist training programme. The research protocol should be developed early in training, approved by a supervisor, submitted for institutional ethics review before data collection, and aligned with clinically relevant diagnostic pathology and laboratory medicine priorities in South Africa.

Given South Africa’s pathology priorities – including HIV, tuberculosis, cervical cancer screening, breast cancer diagnostics, haematological malignancies, anaemia, antimicrobial resistance, transfusion safety, laboratory turnaround time, diagnostic accuracy, and quality assurance – pathology research topics should be practical, ethically sound, and relevant to real-world laboratory service delivery while maintaining strong academic and methodological standards.
