Hi folks! I have been on 800mg. Tasigna for 3 mos. and my recent FISH came back NEGATIVE, but my PCR was at 27.9%??? Is that possible since a 0% FISH correlates , I believe to about 1-5% PCR? Do you think the decimal is wrong and my PCR really is at 2.79%??Or, is there a lab error? Anyway, I am very happy with the result overall! My next PCR is in 3 mos. so should I just wait?
Confused- FISH or PCR?

The expectation would be for a lower PCR with a zero FISH. There are some variables which could account for the higher PCR number but overall it seems odd. I would ask the Onc for an explanation since he would have access to the lab information.
