Dr. Lindi-Marie Coetzee

Lindi-Marie Coetzee is a South African laboratory scientist affiliated with the National Health Laboratory Service, with expertise in HIV and tuberculosis diagnostics, laboratory systems, and health economics. Her work centres on strengthening national diagnostic programmes through data-driven evaluation of CD4 testing, reflex cryptococcal antigen screening, and TB molecular diagnostics within public health settings.

Her publications highlight cost analyses of extending CrAg screening thresholds, mobile Xpert MTB/RIF services, and reagent utilisation modelling across a national laboratory network. She has examined the impact of COVID-19 on advanced HIV disease detection, assessed CD4 specimen rejections, and demonstrated how refined turn-around time reporting can uncover inefficiencies masked by aggregated data.

Coetzee’s research demonstrates strengths in large-scale laboratory data analytics, operational optimisation, and policy-relevant economic evaluation. By linking diagnostic performance, quality assurance, and patient access, her contributions support evidence-based decision-making to improve care for immunocompromised populations in resource-constrained, high-burden environments.
