A method and apparatus for measuring a vitamin K antagonizing anticoagulant present in a sample (116), arranged to: irradiate (304) the sample (116) with light from a light source (114) for exciting the anticoagulant through its absorption of the light, the excitation of the sample (116) resulting in a fluorescent emission from the sample (116); measure (306) the fluorescent emission from the sample (116); determine (308) a fluorescence lifetime (τ1) of the fluorescent emission of the sample (116); determine (310) an intensity (A1) of the fluorescent emission at the fluorescence lifetime (τ1); and determine (312) a amount (c) of the anticoagulant, as a function of the intensity (A1) of the fluorescent emission at the fluorescence lifetime (τ1). |
