Material $4 \quad$ Studie zum Nachweis eines MammaCa In einer Studie soll die Aussagekraft eines neuen Schnellitests für den Nachweis eines Mammakarzinoms untersucht werden. Hierzu wird ein Kontrolltest/Referenztest mit einer 100\%igen Sensitivität und Spezifität genutzt, um die Aussagekraft des neuè Testverfahrens zu prüfen. In einer Untersuchung wurde bei insgesamt 600 Personen das neue Schnelltestverfahren für Mammakarzinom durchgeführt und anschließend der Kontrolltest/Referenztest vorgenommen. Dabei ergab sich, dass bei 200 Personen beide "Tests" positiv ausfielen und bei 213 Personen beide "Tests". negativ ausfielen. Insgesamt viel bei 299 Personen der Kontrolltest/Referenztest positiv aus.
