How Accurate Is SiPhox?

SiPhox samples are processed at CLIA-certified, CAP-accredited laboratories — the same accreditation standards used by Quest Diagnostics and LabCorp.

SiPhox EasyDraw collects blood from the arm rather than a finger-prick, which reduces contamination risk compared to capillary finger-stick collection methods.

SiPhox is not a diagnostic device — results are intended for wellness monitoring and should be confirmed with a healthcare provider for clinical decision-making.
