By examining these residues much can be learned about ancient economies. Residue analysis, for both blood and plant starches can be used to determine what animals may have been hunted and what plants may have been gathered by early peoples.

As a research tool, Lifeways regularly uses the results of residue analyses. For this purpose we use only creditable laboratories offering competitive rates and the best comparative libraries. Because Lifeways is a large organization, we are frequently available to receive volume discounts on sample processing, a saving that is passed on to our clients.
