A multi-institution workshop made the case for a characterised whole-stool reference material so microbiome measurements can be standardised across labs, addressing the absence of defined faecal inputs.

A study of three children found that the region of stool sampled did not change microbial alpha diversity, while 22 of 176 metabolites varied; homogenising the stool mattered for metabolomics and short room-temperature storage had little effect, which supports simpler home collection protocols within the limits of so small a study.

Expressing taxa as cells per gram of stool showed faecal microbial load varies ~10-fold between healthy people and drives apparent compositional differences: relative-abundance data alone can misrepresent quantitative change.
