My 4 year old daughter has all the symptoms of cystic fibrosis, but has tested negative twice. is there anything else it could be?

Chronic cough/sinus: Unfortunately there are many things it could be. Perhaps it is time to see a pediatric pulmonologist or immunologist?

Help: Your child could have an allergic condition such as asthma and possible food intolerance. You might want to consult a pediatric allergist/pulmonologist, gastroenterologist and/ or a pediatric genetecist to arrive at an answer.

Cystic Fibrosis: It seems your daughter was referred to a peds pulmonologist by her pediatrician; different tests were done to rule out cf. Sometimes geneticist gets involved in testing if any diagnostic controversy. If she has lung issues, the pulmonary doctor will address that. If she has digestive issues, she should have been referred to gastro-enterologist. Talk to her pediatrician who is the best guide.

Further testing: From your description of fatty stools, productive cough and chronic sinusitis listed as clinical findings, i would recommend that your doctor check that the sweat test collected enough sweat to make an accurate measurement of sweat chloride. In addition a CF genotype analysis may be sent. A trial of pancreatic enzymes may be ordered by the M.D. Prmg peds/resp fax 858 259 9689 for?S review records.
