FAQ
Is this the same as Genova's Organix or the DUTCH OATs?
No. Those are different organic acid panels from other labs. This page compares the Mosaic Diagnostics OAT only (one row notes the lab is not named in the listing).
Can New York residents order it?
Several sellers state it is not available to New York residents.
Why do prices differ so much?
Sellers set their own prices for the same lab's kit and may bundle practitioner authorization, consultations, shipping or add-ons. The table shows the price and any separately listed fees as posted on each seller's public page on the date checked.
How current are these prices?
All prices were checked on Oct 19, 2026. Prices and availability (including state restrictions) change; confirm on the seller's page before ordering.
