Emerging data from the management of patients with coronavirus disease 2019 (COVID-19) suggests multi-systemic involvement, including the hemopoietic system. The haematological manifestations of COVID-19 include blood count anomalies notably lymphopenia and neutrophilia which are of prognostic significance. ⋯ Furthermore, there is considerable evidence of a distinct coagulopathy associated with COVID-19 characterised by elevated D-dimers and an increased risk of thrombotic events. This comprehensive review summarises the latest evidence from published studies and discusses the implications of the various haematological manifestations of COVID-19 with a view to guiding clinical management and risk stratification in this rapidly evolving pandemic.
