What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Correlation of Microbiome to Disease via Relative Abundance Found in Microbiome Sequencing
Time Frame: One year
Relative abundance of bacterial classes within taxonomic phyla and, more broadly, within their domain will be analyzed by sequencing the gut microbiome. These data will then be categorized among specific gastrointestinal disease types.
One year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Validation of Sequencing Methods
Time Frame: One year
To validate the methods used to sequence samples
