HealthPath - Sibo Breath Test (UK)

Hi all, so I'm doing my Sibo breath test tomorrow..using HealthPath as we don't have triosmart in the UK.

For anyone that has done the HealthPath test or similar, apart from the pre prep diet are there any tips or advice I should be aware of.

I want to make sure I do it all properly so be good to get any useful feedback is anyone ran into any issues or anything when doing theirs. Thank you 2 random questions....

1) Should you blow or like breathe. The only reason I ask when using FoodMarble they ask you to blow softly like you are cooling soup, but the instructions for HealthPath just say take a normal breath then breathe.

2) Should you hold your breath for 3secs before blowing, again this is just something FoodMarble mentions before using their device, but not HealthPath test.

Or can it be either or really and doesn't really matter thanks.
