Laboratory requirement
Die in grün gezeigten Gene sind kuratiert und werden als Gen-Panel untersucht. Eine Erweiterung des Panels (blau gezeigte Gene, jeweils ebenfalls kuratiert) kann auf Anfrage erfolgen. Sofern unter "Erweitertes Panel" ein Minuszeichen angezeigt wird, sind nur Core-/Basis-Gene verfügbar.
Für die Anforderung einer genetischen Untersuchung senden Sie uns bitte die Krankheits-ID auf einem Überweisungsschein. Bitte die Material-Angabe beachten.
Für privat versicherte Patienten empfehlen wir einen Antrag auf Kostenübernahme bei der Krankenversicherung.
Die Untersuchung wird auch für Selbstzahler angeboten.
