It means you are going to live a very long life.

Just an FYI : patients often show initially both p210 and and to a much lesser degree p190 transcripts (a transcript is a protein created by the gene). Having both usually leads to a lower response to imatinib than second line TKI's (I had both transcripts, but p190 quickly disappeared).
I found it interesting your lab was testing for p230. That is a very rare mutation in the bcr-abl domain. Surprised they did the test. No matter - you don't have it.

Your BCR-ABL is < 0.01% This is scientifically, given the limits of the technology, indistinguishable from "not detected".
