Additionally, a study of 50 patients at least 6 weeks post-infection with COVID-19 showed plasma ADAMTS13 levels were significantly reduced when compared to healthy controls (Lower limit of normal local reference for the study 399 ng/mL [Median 598 ng/mL vs. 630 ng/mL, p = 0.009]) [49]. Here, ADAMTS13 is linked to COVID-19.
