ROTEM® platelet- Reagents


The ARATEM test enables the assesment of platelet function e.g. after  cyclooxygenase Inhibition and offers therefore a fast evaluation of the platelet aggregation via platelet activation with arachidonic acid. The ara-tem will be delivered as a single use reagent. The interpretation of the result can be made within 6 minutes. Pathologic results with ARATEM can be found under the following clinical situations:

  • Cyclooxygenase inhibitors (e.g. patient treatment with acetylsalicylic acid, e.g. Aspirin®)

  • Platelet dysfunction due to e.g extracorporeal assist devices, surgery, or similar

The reagent contains all compounds required for the assay in lyophilized form and is reconstituted with 20 µl ROTEM® platelet Diluent.
