Marker Guide
Lactate-producing microbes
What this marker measures
Lactate can be produced by both host cells and gut microbes. Microbial lactate is generated during carbohydrate fermentation and may be converted by other bacteria into short-chain fatty acids such as butyrate or propionate, or absorbed and used by the host.
This marker is included to provide additional exploratory context; however, the clinical significance is not yet well established and the evidence base is less developed than for Microba’s core microbial markers. It should be interpreted with caution alongside the broader report and clinical picture.
Research Use Only
Lactate is an organic compound produced through the microbial fermentation of carbohydrates.
Marker summary
Lactate, produced by microbial fermentation of carbohydrates, can be converted to propionate or butyrate.
