What is a sweat test?
A sweat test is done to test for cystic
fibrosis. During the sweat test, a small
amount of sweat is collected from the
forearms. The amount of salt (chloride) in
the sweat is measured. A sweat test is done
when a patient has symptoms of cystic
fibrosis (CF), a family history of CF, or
when a newborn has a positive screening
test. If the sweat test is being done after a
newborn screening, you will meet with a
genetic counselor during this visit.
How is a sweat test done?
Two electrodes are placed on your child’s
forearm for five minutes. These cause the
sweat glands to produce sweat. This
produces a mild tingling feeling, but is not
painful. A collector is placed on the arm to
collect the sweat. Once the sweat is
collected it is taken to the lab for testing.
Will it matter what my child has to eat or
drink before the test?
No, diet will not affect the sweat test results.
What if my child is taking antibiotics or
Your child should keep taking medicines as
What if my child has a fever or a rash?
If your child has a fever or rash, please
contact the sweat test coordinator at the
number on the reverse side of this page.
Will I stay with my child during the test?
Yes, parents stay with the child. This test is
not painful. It will help if children have
something to keep them busy (such as a
pacifier, bottle, special toy, or book) during
the test. There is a play area in the waiting
room for toddlers.
How long will the test take?
It takes about one hour to complete the
sweat test. If your child is having the sweat
test after newborn screening, the visit will
take about 2 hours because you will meet
with the genetic counselor after the sweat
test is started.
When will the results be ready?
Results are ready about one hour after the
sweat test. Test results are sent to your
child’s provider. You can call your
provider’s office to obtain the results. If
your child is having the sweat test after
newborn screening the genetic counselor
will give you results, and test results will
also be sent to your child’s provider.
