Hi Clare
We had the same feelings following my mums sct august 2012. We just expected the pp's to be zero and we were terribly disappointed when they were 2. However, I spoke to Maggie the nurse on here who explained not everybody gets to zero pp. The melphalan keeps working for months after, so they can still fall. Also, although everyone would like a zero reading, what the medics are looking for is the stability of that number, whether it is 2 or 6 for example, its for that figure to remain stable. We now do not ask for the pp levels. I think its too easy to be fixated. The consultant will advise Mum should there be a rise and need for concern.
Tell your Mum she's doing really well:-)
