  1. Nasal Potential Difference Test for Cystic Fibrosis - Topic Overview

    The nasal potential difference test (nasal PD test) measures how well salts (sodium and chloride) flow across the mucous membranes in the nose. This type of test can be helpful when the results of a sweat test or a genetic test are not clear. In this test, electrodes are placed inside the nose and liquids are run through the nose. There is also a needle placed in the forearm that connects to a machine. Because this test can be uncomfortable, your child may need medicine to help him or her relax before having the test. This test is not used very often because it can be difficult to do and because it is not available in many places.

  2. How Cystic Fibrosis Affects the Bones - Topic Overview

    Many people who have cystic fibrosis have low bone mineral density, because they have problems absorbing vitamin D and calcium, which are necessary for strong and healthy bones. Low bone mineral density can make a person who has cystic fibrosis more likely to have bone fractures or to develop osteopenia or osteoporosis in adulthood.Routine dual-energy X-ray absorptiometry (DEXA) tests can check the density and strength of your bones. Spending small amounts of time in the sun, exercising, taking vitamins, and eating nutritious foods can help prevent bone problems. People who have cystic fibrosis may also have painful or swollen joints (arthralgia or arthritis) from time to time. Often these joint problems do not last more than a week and any pain can usually be treated with nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen.
