Daye’s diagnostic platform brings clinician-level accuracy to at-home testing - improving uptake, reducing barriers, and supporting informed clinical decisions.

Why partner with Daye?

Improved patient access

Self-sampling significantly increases completion rates, including among patients who avoid speculum exams or phlebotomy, resulting in more reliable follow-through.

Clinically validated diagnostics

High-yield tampon samples support accurate HPV, STI, and microbiome PCR testing from a single specimen. Venous-validated capillary devices provide reliable at-home hormone measurement.

Exceptional operational
efficiency

Reduce in-clinic workload by shifting sampling out of the exam room while maintaining diagnostic accuracy and lowering invalid/insufficient samples.
