Completed Test

The third, and last, part of the examination of water for the presence of bacteria of fecal origin. Cultures that are scored as positive in the earlier steps of the analysis (Presumptive Test and Confirmed Test) are subjected to a verification by inoculating appropriate media (eosin methylene blue agar plates) and performing a gram-positive/gram-negative stain on isolated colonies.
