I can understand your anxiety. My children have been sweat tested recently and the procedure that Ashley described was very similar to the tests we had run.
Our CF center only does testing before 11 am, so we have had the results each time by 4 pm. This was extremely helpful as I was anxious to know the results.
Are you having your 3 yo tested at an accredited CF center? If not I would reccomend changing the appointment. Accredited CF centers run the test more frequently and have more reliable results than non-cf centers.
Also as a guide for reading sweat test numbers the results read like this:
0-39 normal
40-59 borderline
60-up positive
When you recieve your results be sure to ask for the sweat chloride number and not just a positive or negative. There are also many people on this site who had "normal" sweat chloride numbers who have actually had CF. My daughters are currently in the process of having the extensive genetic testing (testing for all 1500+ mutations)completed after their sweat tests came back at 38&39. When I initially asked for their results it was told to me they were negative, and only upon further research did I discover there is some grey area in the normal values.
I know nothing can relieve your anxiety at such a stressful time, but I do hope this info helps your family understand more of what will be going on. <img src="i/expressions/heart.gif" border="0">
