Comparison of ADAMTS13 assays with FRETS-VWF73 and FRETS-rVWF71. (A) Citrated plasma from subjects with thrombotic microangiopathy (closed circles), other causes of thrombocytopenia (open triangles) and healthy controls (open squares) were assayed with FRETS-VWF73 and FRETS-rVWF71. Linear regression (solid line) gave a slope of 0.92 and R2 of 0.95. (B) ADAMTS13 inhibitors in samples from 34 subjects assayed with FRETS-VWF73 or FRETS-rVWF71. Linear regression (solid line) gave a slope of 2.51 and R2 of 0.80.
