One way to test this is to have say 10 people in the room, 5 of whom have their phone on, the others have their phone off (anyone who does not have one is given one and told not to look at it to see if it is on or off). If she can tell who has their phone on then you should take her seriously.
If you do this then the 10 people must not know what you are testing. The only person who knows which 5 people have their phone on or off is not in the room when the person who says they can tell is in the room. This makes it close to a double blind study.
...which will then get handwaved as "oh, I got this so intense headache from a whole 5 phones that I didn't know which direction the pain comes from any more."
IIRC the way that was tested was, pretty much, send one person in whose phone may be on or off, and see if the "allergic" one can tell if it's on or off. ETA: Repeat until you have enough of a sample, obviously.
