Zoe: Too tired to think of witty headline (+37)

Not sure if Sonny's recent dip is entirely GVHD now. They think there is some GVHD but its so 'low grade' they want a bit more of a fight so they are going to start to reduce the dose of another of the immune suppressing medications he's taking. His tummy has settled down but he's still spiking high temperatures which could be a viral infection as his 'markers' have gone up from 7,000 copies to 36,000 copies. This sounds horrendous but the doctors say a viral infection is to be expected and they have to treat the smallest sign of it. 36,000 is a tiny number in medical land. If thats true then why can't they just say 36?
