I had two years PCR results Not detected. Recently relocated to another state, the lab also changed, the PCR result come out to be 0.045% IS. This really worried me.
You are here
PCR result arise

Hi,
This can be a problem for those tested in labs (particularly in the US) that do not use a suitably sensitive Q-PCR method. It is likely that the previous lab used did not find Bcr/Abl evident because of that, and that your current lab is using a more sensitive test method. If this lab is tied to the International Standard then you should not worry- your result is very very low. Wait until the next result and then compare- it is very likely to be the same and remain stable, which is what you should be looking for. Any result under MR3 (0.1%) that is stable is indicative of disease that is highly receptive to TKI therapy - which is a good thing.
Best wishes for the new year,
Sandy
