Good question! This is time the practitioner has dedicated to you to do your report. The practitioner will use that time to look over your scan, create your recommendations list and send you your scan reports. They will also send you an invoice for the recommended infoceuticals at that time, so you'll know when to expect it.
Book your allotted time slot and then, on the same day, do your scan. This will assure that all information is as current as possible and your scan does not accidentally get passed over.
