Disclaimer: I was tested, but have not had my children tested, so no, not in exactly the same situation.
But I would reassure you that IQ is just a number (and one with a confidence interval, moreover). And I say this as someone with more day-to-day experience with that number than most. The qualities you see in your DC won't disappear if the number comes back as 125 instead of 135. She will be the same curious, creative, and loving child that you knew before the test, and you will love her exactly the same way. The ways in which she has already demonstrated that she shares traits with you and your spouse will not have changed. You'll just have one more (isolated) data point about how she performs on a particular narrow set of tasks. Useful, but only one part of her, and not even the most important part.
