Method for presenting thrombosis and hemostasis assay data
First Claim
1. A method for presenting the relationship between data from an assay relating to thrombosis-hemostasis on an unknown sample, and data from a plurality of assays relating to thrombosis-hemostasis from known sample populations comprising:
- (a) providing data from at least one time-dependent measurement for each of a purality of known blood samples;
(b) measuring a property over time to derive at least one time-dependent measurement on an unknown blood sample;
(c) transforming data from steps (a) and (b) to at least one predictor variable which captures information content of both the unknown blood sample'"'"'s at least one time-dependent measurement and the at least one time-dependent measurement for each of said plurality of known blood samples;
(d) creating a topological feature map of the at least one predictor variable from step (c) of the plurality of known blood samples in step (a) whose spatial locations within the topological feature map correspond to intrinsic features of the at least one predictor variable;
(e) determining the position on the topological feature map of the unknown blood sample corresponding to the unknown blood sample'"'"'s at least one predictor variable; and
(f) presenting the position of the unknown blood sample and the positions of the plurality of known samples used to create the map in step (d) on the map created in step (d).

Abstract
A method for presenting relationships between data from a thrombosis-hemostasis assay on an unknown sample and data from a purality of assays on known samples, which can be in the form of a topological feature map wherein spatial locations within the map correspond to intrinsic features of the known samples. The position of the unknown sample is superimposed on the positions of the known samples. An alternative presentation is showing the distance of each of a purality of predictor variables from an unknown sample to the mean values of a known population.
