Hi scuba,
Two years ago i changed to nilotinib from imatanib without taking mutation test. After taking nilotinib my pcr is always between 4 to 4. 5.
My question is, just assume i have mutation two years back. If i take mutation test now would the mutation test detect that mutation. Bec its already two years since i changed yo nilotinib also my pcr is 0071.
I read that if pcr is below 1 its hard to find mutation using sanger method and even new generation sequencing method.
