,9 Similarly, other investigators have shown high CRP and D-dimer, as important inflammatory markers, and thrombocytopenia to strongly correlate with COVID-19 disease severity and prognosis.10, 11, 12, 13 These findings suggest that potential biological differences in host response to COVID-19 occur between ethnic groups, identifiable in routinely collected biochemical data. The gene discussed is CRP; the disease is Thrombocytopenia.
