She has undergone multiple blood tests, CT's and MRI's in an attempt to find the problem. In the meantime, she is on an antibiotic to fight a possible infection. They have also tested for an embolis, pneumonia, H1N1, leukemia and cardiac function. She is on continuous oxygen because her O2 saturation drops. The cause of that problem has not been diagnosed.
A fluid sample was taken from the pleural space of her lungs for testing. At one point, she was in an isolation room because of her suppressed immune system. At this point, there is no indication that the leukemia has returned. We hope to have some additional news by tomorrow.
