Here are a few links that caused me to ask if anyone knew about sweat test results varrying with menstrual cycle.
Cigna Health Insurance site:

. Adults generally have higher salt concentrations in their sweat than children. Also, sweat test results in adults can vary widely. This is especially true in women, because the amount of salt in their sweat can vary with the phase of their menstrual cycle.
I see the same wording on this hospital website.

I found the same exact wording on other health insurance websites. I was wondering if any adults maybe who are having their sweat test redone as now before and after Kylodeco (sorry for spelling) are watching that they test on the same time of the month so they compare apples to apples. Or maybe the chagne is not that significant.
Sort of related I have a friend going though infirtility and she is using a firtility testing kit that tests salt on levels on the skin from sweat and tracks changes to determine ovulation and it shows changes enough throughout the cycle on this home system to tell when a women is ovulating. The following website shows a chart of the changes in the salt on the skin it uses to detect ovulation. Maybe it measures the same thing salt as the CF sweat test although a lot less accurately? I don't know the answer to that, but was hoping someone else would know.

I am not a medical profession and just as out of curiousity since my pre-teen was just tested and now I was tested and don't know my result. According to the ovulation kits website I just got tested at what would be my lowest numbers of the month.
If women are using the sweat test to prove to their insurance that Kalydeco is working they may want to track that they recheck at the same time of the month to prove improvement? Or is this not that important?
