My daughter is 7 years old. After 5 years of foamy, floating, suspicious looking stool, a positive fat malabsorption test, 3 significant episodes of GI bleeding, 3 colonoscopies with biopsies showing neutrophilic infiltration and lymphoid hyperplasia, as well as a strange lesion in her colon that doctors could not identify, my insurance company (Blue Shield of CA) turned down authorization for an Ambry Amplified genetic test. The basis for their decision was "no family history" and "negative sweat tests". (Sweat tests were 32/33...anyone who knows anything about CF knows that sometimes you can have negative results close to borderline and still have a problem!) I am not an expert, nor am I a doctor, so I by no means presume to know that she has CF on my own account, but why not rule it out so we can move on from here, or deal with it if need be? Hasn't she had enough puzzling symptoms to justify diagnostic testing? Sorry to vent; it's just been a long road...
