Sweat Test

Cystic Fibrosis Sweat Test, Iontophoresis Test (Sweat Test)

Risks

There is very little risk of complications from this test. But the test should always be done on an arm or leg (not the chest) to prevent the possibility of electric shock.

The electric current may cause skin redness and excess sweating for a short time after the test is done. In rare cases, the current may make the skin look slightly sunburned.
