Expected vs. observed ADAMTS-13 levels recorded with 11 methods for test plasmas. Panel A, functional assays; panel B, antigen assays. Data points for each test plasma represent 10 repeated determinations taken on different occasions. Horizontal bars represent mean values. Plasmas with observed levels below detection limits were omitted from calculation. Observed ADAMTS-13 levels were expressed as % of the local reference standard, except for methods 5 and 8, which were expressed as % of the common standard.
