Zusammenfassung

Point-of-care-Tests (POCT) mit Vollblut gibt es für verschiedene Analysen im Bereich der Hämostase. Am häufigsten wird die Thromboplastinzeit mit Kapillarblut durchgeführt. Diese POCT-Analyse ist zuverlässig und wird u. a. bei der Patientenselbstkontrolle der oralen Antikoagulation eingesetzt. Die aPTT als POCT ist teilweise problematisch, deren Einsatz muß kritisch erwogen werden. Der PFA-100-Analyser ist geeignet als Screeningtest für Thrombozytopathien und ausgeprägte Von-Willebrand-Faktor-Mangelzustände. Die D-Dimer-Teste mit Vollblut erfüllen die Anforderungen bezüglich hoher Sensitivität nicht immer.

Die Einsatzmöglichkeiten der Hämostase-POCT-Analysen müssen kritisch und wissenschaftlich definiert werden. Diverse Aspekte wie Qualitätskontrolle, Kosten und Gewinnung der Vollblut-Proben müssen weiter bearbeitet werden.

Summary

Several point-of-care tests (POCT) or near patient testing systems using whole blood are now available for hemostasis tests. Determination of the prothrombin time is accurate and safe using these systems. More studies, however, are necessary to define the place of the POCT activated partial thromboplastin time in monitoring heparin therapy. The PFA-100 analyzer is a valuable tool for the detection of platelet function disorders and von Willebrand disease. There are potential problem areas in POCT, such as quality control, costs and blood sample collection and handling which need more work to be done.
