If I understand what you wrote, you had blood work done and they checked for CML?
Why did they check for CML, did you have symptoms? Most important, what was your CBC results (i.e. blood counts). Are your white blood cell counts in the normal range(s)?
If you did not have CML symptoms AND your blood counts are "normal", then having a test for CML made no sense.
Any PCR test result (i.e. b2a2, b3a2, etc.) < 0.01 is indistinguishable from "undetected" statistically. This is a false positive in your case and meaningless - especially since you are not undergoing treatment for CML. This is why your report has the three numbers all the same.
Without a CBC report, it's hard to know if something else is going on with your blood which led the doctor to order the tests.
