    The study evaluated microbiome testing methods across five French laboratories, revealing significant variability in kit content and procedures.

  • 2

    Discrepancies in report formats and regulatory compliance were noted, with report lengths varying from 9 to 36 pages.

  • 3

    Analytical approaches varied widely, with no laboratory providing raw sequencing data, leading to contradictory interpretations of microbiome health.

  • 4

    Health recommendations from laboratories were often non-personalized and based on dubious sources, raising concerns about patient safety.

  • 5

    The findings highlight the need for improved regulatory oversight and standardization in microbiome testing to enhance reliability and consumer trust.
