The 72hr interval reflects a shift in our collection guidance based on the analytical characteristics of our assay.
Our platform utilizes PCR-based methods, which identify microbial DNA rather than relying on organism viability.
As such, the assay is less dependent on full microbial recolonization and can detect residual or persisting microbial signatures even in the setting of recent antibiotic exposure.
Our collection will likely reduce the likelihood of acute antibiotic interference at peak concentrations and allow for initial microbiome stabilization post-therapy.
For certain clinical scenarios, a longer washout period may still be considered at the provider’s discretion.
