What does the report say the FISH result was? Should be a percentage.
nuc ish(ASS-ABLx3),(BCRx2),(ASS-ABL con BCRx1/(ASS-ABLx2),(BCRx2),(ASS-ABL con BCRx1)/(ASS-ABL,BCRx2
It appears the lab used several different FISH probes looking for various nuances in your Philadelphia Chromosome. The numbers inside brackets such as  are supposed to be a result but it should always be written as [X/Y] where X is the number of leukemic cells found out of Y number examined (often about 200 - 500). So I do not know why your lab result does not report the Y value. Again, what did the report say?
CD34 cells are immature cells, also called blast cells. Yours says less than 5%, but unknown how much less. Maybe 1% for all anyone knows.
