From: Low FXIII activity levels in intensive care unit hospitalized COVID-19 patients
AÂ Mixing FXIII activity assay performed on plasma of four severe COVID-19 patients with low FXIII activity levels show significant increase to normal range values. Baseline and mix (1:1 with normal plasma) results are shown (p<0.0001). Dashed line, the lower threshold of normal FXIII activity range. BÂ FXIII-A antigen levels in COVID-19 patients. FXIII-A antigen levels were determined, and correlated with FXIII activity in the same samples. R2 value of the regression comparison between the antigen and activity levels are indicated.
