P190 an p210 is a gene mutation they look for. If your meds are working and it's not detectable then your body is working with the meds and letting your Gene's mature.
I have cmlph+. My DNA will never go back to where it was before. I will always have this mutation. It is due to the fact that our chromosomes have split, an reattached to another. Making a new gene.

its to do with the philadelphia chromosome done by bone marrow . its a reflex testing for certain cancers especially leukemia forms CML.
.

I'm not sure what that means but when I see undetectable it's time to celebrate and thank you Jesus

Thank you so much!

Thanks so much Anita! I think they mean something about the Philadelphia chromosome....but I was told I would always have them?
