Patent ID: 8501429

Claim:
A method for quantitatively analyzing an anticoagulant in a sample, wherein the method comprises the following steps: a. providing and incubating a reaction mixture comprising i. the sample, ii. a defined amount of an activated coagulation factor whose activity is directly or indirectly influenceable by the anticoagulant to be determined, wherein the activated coagulation factor is present in a separate reagent which is added to the reaction mixture, iii. a cleavable substrate which has at least one cleavage site for the activated coagulation factor, iv. a solid phase to which the cleavable substrate is bound or becomes bound during the incubation; b. separating the solid phase; and c. determining the amount of solid-phase-bound, uncleaved substrate, wherein the determined amount of the solid-phase-bound uncleaved substrate indicates a quantitative measure of the anticoagulant in the sample.
