From Hematologistʼs desk: The effect of COVID-19 on the blood system To the Editor:

Fan et al. critically studied the difference in hematological parameters between the ICU vs non-ICU COVID-19 cases. 1 The study underscores the pertinent hematological parameters, which might help the treating physicians to anticipate ahead of time regarding the potential need of the intensive level of care. COVID-19 is a rapidly evolving and emerging disease, and AJH readers would certainly benefit from further discussion and refinement.

Concern over coagulation abnormalities in COVID-19 patients: Fan et al did not discuss the coagulation parameters of their patient series. 1 Currently, the exact significance of coagulopathy in COVID-19 patients is yet to be determined. But preliminary results from recent studies have shown that a high D-dimer value correlates with ICU requirement and a higher mortality, when compared to individuals with normal/mild elevation of the D-dimer levels. 2 System, Singapore recently published a case series of two patients who presented to the hospital for fever and myalgia. 5 On evaluation, they were found to be mildly thrombocytopenic and tested positive for dengue fever.
