My granddaughter screened positive for CF. My daughter took her to the Loma Linda CF clinic yesterday-where she was completely overwhelmed and left completely confused. The Dr. at Loma Linda said that Kathryn, my granddaughter, had a rare combination of genes, and that they would need to determine if they both came from Mom or if one is from Mom and one from the father, so they took blood from my daughter for testing and scheduled a sweat test for Kathryn next month, her two sisters will also be tested. My daughter followed up with her pediatrician, who immediately had her meet with a pulmonary specialist. All this was in the span of one afternoon-so when the counselor at the CF clinic asked my daughter if she had any questions she was completely dumb founded. The counselor told my daughter that these are all just tests, and anything conclusive is going to take some time. So, she screened positive, but they have identified some gene-OK, what does that mean? What numbers should my daughter ask for? Should she call the clinic back and ask what the "rare" gene combination is? She really needs to know what she is looking for. Thanks to anyone who can help!
