The heel prick test can produce false positive results. The extra testing will ensure that the test was correct. Also gene type testing will provide your nephew with the best possible start if he does have CF. I wish I had a definate answer to provide you with, to ease your minds a little.
It must be scarey too think your nephew may have CF, and the wait for the test and result will be a painful one, as it is a slow process. Unfortunately, heel prick tests will never be accurate, they just manage too get people on the right track more often than if there was no test.
Hope the extra tests come back negative, and that you can all move on. Keep in touch and let us know how you are getting on. Feel free to ask any questions you need answering.
All the best
