Dr. Susan Louw

Susan Louw is a South African laboratory hematologist and academic researcher whose work centers on coagulation, endothelial dysfunction, and thrombotic disorders in the context of infectious diseases. Affiliated with academic hospital practice in Johannesburg, her research bridges diagnostic hematology and clinical medicine, with a strong focus on HIV-associated complications and laboratory quality systems.

Her scholarship explores the mechanisms underlying HIV-associated thrombotic thrombocytopenic purpura, highlighting the roles of ADAMTS13 autoantibodies, complement activation, and endothelial inflammation. Additional studies investigate biomarkers of coagulation and inflammation in HIV, COVID-19, and other viral infections, emphasizing immunothrombosis, cytokine activation, and cardiovascular risk. Work on endothelial GM-CSF pathways further reflects interest in translational mechanisms linking chronic infection to vascular injury.

Louw also contributes substantially to laboratory practice through verification of hematology and coagulation assays, external quality assurance programs, and implementation of specialized tests for hemophilia management. This combination of mechanistic research and diagnostic validation underscores expertise in integrating laboratory science with patient-centered hematologic care.
