Most microbiome studies measure relative abundance of the various microorganisms in a sample. This study demonstrates the feasibility of large-scale measurements of absolute microbial concentrations. Moreover, it demonstrates how sample handling and storage methods can alter microbial measurements, potentially introducing bias in conclusions drawn about microbiome–host relationships.
