title: [Monitoring anticoagulant treatment with the KEM-O-MAT 2HP autoanalyzer].
abstract: Synthetic chromogenic substrates were adapted to KEM-O-MAT 2HP for an automated monitoring of anticoagulant treatments, determination of factor X (S 2337) in oral anticoagulation, anti-Xa (Hepachrom) and anti-lla (S 2238) activities of heparin in prophylactic and curative heparin therapies. In all cases, these methods revealed high sensitivity, reproducibility, and a good correlation of their results with those of classical clotting assays. The present cost of synthetic substrates seriously limits the potential value of chromogenic assays for routine controls. However, the development of automated amidolytic techniques should provide an easier standardization in the laboratory control of anticoagulant treatments.
