We sequence ALL microbial DNA—not just one bacterial gene like 16S tests. This means we can detect any of 120,000+ bacteria, viruses, fungi, parasites, and archaea at species and strain level. In our sample data, we detected 1,772 unique organisms including beneficial bacteria (Faecalibacterium, Akkermansia), pathogens (Campylobacter), and fungi most tests miss.
