See Esyir's response. In short, we do NOT look up your DNA, and only look into microbial DNA. In fact, we do a host depletion step to enrich for microbial DNA prior to sequencing, then a following host depletion step prior to microbial mapping. Sequencing will inevitably pick up some signal from the host genome, but at such low levels, we cannot derive meaningful signal from the host DNA.
TLDR, we do NOT use host genetic data, but cannot guarantee that none of that data will be stored somewhere in this analysis
