Can you check through JQuery if a tab of the same ID has already been created?

Question

I have this script that creates a new tab in JQuery. Can you check through code on whether that particular tab has been generated?

Thanks!

        function createTab(name) {
            var tabName = "#fragment-" + name;
            $("#container-1 > ul").tabs("add", tabName, name);
            var newTab = $(tabName).css("display", "block");
            newTab.html("<iframe src='ViewPatient.aspx?pname=" + name + "' width='100%' frameborder='0' scrolling='no' height='300'></iframe>");
        };
