Wrong sweat test result because of pretzel?
- Question
- Hello,
my 4-year-old son will have a sweat test next Monday because of the many bronchitis he has had. Today, he ate a pretzel and yesterday some salt sticks/pretzel sticks. Could this cause a wrong result?
Furthermore, he inhales Flutide 125 µg twice per day, does this drug has any influence on the test result?
Best regards, J.
- Answer
- Hello,
A pretzel stick cannot influence the result of the sweat test.
A sweat test result CAN be influenced significantly by certain drugs (Kalydeco™/ivacaftor). However, food and salts that are ingested increasingly cannot cause such a significant influence on the result.
The drug Flutide will have no such influence either. Furthermore, if the sweat test is conspicuous, the sweat test result will be controlled anyhow.
Best regards,
