I'd like some feedback and suggestions for labs in the USA. Specifically, I'm looking for in-depth evaluation of methylation (and ideally more comprehensive metabolic pathways) status; and of course MTHFR and other more comprehensive genotyping. Is there a lab which offers comprehensive genotyping in the US? Is DDI the best insofar as completeness with methylation profiling? I'd like to hear experiences from those who've had these tests performed recently. Thank you.
