So if I had it on Friday, the PCR test should still be detecting it.

Change that "should" to "might" and that would be a better statement of how it works. A PCR test is more accurate, but the processed in a lab type is best.
How about "has a high probability of".

This was a lab processed test, sample collection and processing was all done in-house at Stanford Medical Center. That's also how they manage to get 12 hour turnaround for results.
