I was dx w/ CML in July 2012, and have been PCRU since Oct 2013 (3 different PCR results of 0.000% IS as done by Quest Lab), until earlier this week. My PCR from my blood draw at Quest this past Monday came back at 0.043%. I take 100 mg Sprycel.
My hemo called me Thursday about this result and said to get a retest next month, to determine if it is a lab error or if it is really increased. He said if it is increased that I will have a mutation test performed. (I think - I was in shock hearing all this but I think the above is pretty accurate). He also mentioned about a bone marrow biopsy as well.
Was hoping someone could answer this question - is it possible or common to have a messed up PCR lab result? ALso - Is it possible that the cml could increase 1-2 orders of magnitude in a little over 3 months? My last PCR that was 0.000 was June 30, 2014. That seems like a very rapid increase.
thx for any thoughts on this...
