If you are interested in who is doing 100% PCR based testing for pathogens, bacteria, toxins, viruses etc then you need to use DRG Labs based in Atlanta. It was originally set up up by Tony Hoffman (who was instrumental in developing the Metametrix GI profiles) after he left during the take over by Genova.
They do all markers by PCR except the GI health markers by ELISA inc. anti-gliadin IgA, split sIgA1/sIgA2, lactoferrin, calprotectin etc. Also they do quantitative H.Pylori with virulance factors CagA/VacA.
They also include C.albicans, C.Tropicalis. and Blastocystis for European Market, not sure for US market.
Turnaround times are 3-5 working days from single stool 5ml sample.
