HPCSA Biochemistry Registrar Research Requirements

All HPCSA biochemistry 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 clinical biochemistry, chemical pathology, laboratory medicine, and metabolic health priorities in South Africa.

Given South Africa’s biochemistry priorities – including diabetes, dyslipidaemia, chronic kidney disease, liver dysfunction, thyroid disease, vitamin deficiencies, HIV and TB-related biochemical abnormalities, cardiac biomarkers, inflammatory markers, toxicology, laboratory turnaround time, quality assurance, and rational test utilisation – biochemistry research topics should be practical, ethically sound, and relevant to real-world laboratory and clinical service delivery while maintaining strong academic and methodological standards.
