O.k., Trey, this one's for you. . .
Went in for PCR test this morning. They did the typical draw. Was in the parking lot putting on motorcycle gear (good thing I'm slow), when the lab tech came running back out because the doc wanted another draw for a fusion test (green topped vial). Lab tech tried to explain what and why, but I couldn't get much info out of her. Did some online research and found the test, but didn't get much info that helped me out.
Is this a test they should have been doing all along? Was it necessary? Is it something that can even be compared to current numbers, or will it be something to use as a new baseline? The tech said that the doc has recently started doing this test with all of his patients.
