They are redoing the blood culture. They do that anyway. But they think that there might some sort of contaminant in yesterday's sample. The nurse said that there are plenty of false positives.
The nurse also said that it could be negative because after one dose of Tylenol yesterday and one dose today as a premed for his transfusion, he has no fever at all. The nurse has no problem talking with us about this stuff and the "what ifs" and such. The pediatrician on the floor is generally in a hurry. The oncologist will absolutely talk with us for whatever we need as well.
