Thanks again Alyssa for responding. Yes, my daughtre has been seeing her pulmo since January (every 3 months) and she is from an accredited cf facility. The test was also done at that facility. It was the nurse who called on Friday and said the test was "negative". I then asked for numbers and she said 31. She was also going to e-mail our pulmo because she though that she might want us to come in earlier. We'll see. Thanks again, T
