nah, don't think you need a scan then
i'd definatly skip it if it would mean sitting around and wait for results...
how come it takes so long??? the person doing the scan can tell you what they see right?
i'd ask them for your results from last time, if you want to know them that is, they should
be in your file, easy access, if they make you wait for hours for that too... pls allow me to come and smack them?
