Abstract

This disclosure provides methods for determining relative abundance of one or more non-host species in a sample from a host. Also provided are methods involving addition of known concentrations of synthetic nucleic acids to a sample and performing sequencing assays to identify non-host species such as pathogens. Also provided are methods of tracking samples, tracking reagents, and tracking diversity loss in sequencing assays.
