CRP and acute respiratory distress syndrome: Along with the elevated levels of CRP, increased amounts of D-dimer have also been observed in infected pregnant women (Areia and Mota-Pinto, 2020; Zhou et al., 2021), and research suggested that elevated levels of D-dimer may have led to the progression of COVID-19 disease severity in several pregnant women since high amounts of D-dimer signified an increased chance of acquiring Acute Respiratory Distress Syndrome (ARDS) and being admitted into the ICU and dying (Vidali et al., 2020).
