Dr. Doreen Jacob

Doreen Jacob is a South African laboratory medicine researcher whose work centers on clinical chemistry, therapeutic drug monitoring, and public health laboratory systems. Her scholarship reflects a strong engagement with diagnostic quality assurance and the optimization of laboratory services within resource-constrained healthcare environments.

Her research on immunosuppressive drug measurement evaluates the comparability of mass spectrometry and immunoassay platforms in transplant settings, highlighting analytical performance, cross-reactivity concerns, and clinical implications for patient management. This work underscores expertise in method validation, assay performance assessment, and the practical challenges of implementing gold-standard technologies in diverse healthcare contexts.

In addition, her work examining the impact of the COVID-19 pandemic on non-communicable disease testing in South Africa demonstrates a broader systems-level perspective. By analyzing national laboratory data, she contributes to understanding healthcare access disruptions and their implications for chronic disease management. The current profile is based on a limited set of available publications.
