There are only two products: SWAMI GenoType and SWAMI Xpress. Pro does not exist. Although some people use Pro to refer to the SWAMI GenoType.
Basically there are several hundred additional settings requiring entry.
Incorrect entries with these additional options will degrade the diet recommendations.
To avoid these problems, a consumer product was made that was "idiot proofed" to assure that people got decent diet recommendations.
SWAMI GenoType is available through practitioners that have received training so they know what they are doing when they make settings.
SWAMI GenoType is sold in unit of 10 or 30 patients. SWAMI Xpress is sold for a single user and does not require any training to use.
