The price is based on the amount of work that goes into each report. While people might like to get detailed information about their allergies, and would like to pay $200 for it, we can't review medical records and the literature for that little. Researcher time costs more than that.
Some things that are labeled "alternative medicine" have actual studies, with decent sample sizes and good methodologies, showing that they work. These things are worth paying attention to. The rest don't meet our standards and get ignored.
