Swab test was positive.

I don't know much about the specific tests, but I do know that there have been a lot of different false positives over the past couple of years. Most have been related to other types of things, but I think it's good to take that first test with a small grain of salt. The fact that she is Pakistani is interesting, given the "plot."
