    At-home amyloid screening with a dedicated treatment path after results. Start with the kit, review your findings, and then move into treatment planning if appropriate.

    Amyloid Screening Support

    [email protected]

    Worldwide sample collection and physician-directed follow-up support.

    Screening is informational and helps determine whether the treatment path should be explored.

    This service provides informational laboratory screening only. It is not a diagnosis and does not guarantee treatment candidacy.

    Treatment decisions, if any, happen only after results review and clinical assessment.
