The Daye At-Home Hormone Test
We use an FDA-cleared capillary device to enable accurate at-home hormone testing, validated against venous draws and analysed in CLIA/CAP-accredited labs with cycle-specific clinical reference ranges. Here is why clinicians use it:
Strong agreement with venous serum results
High specificity with excellent patient comfort
Removes common barriers to testing
Fast turnaround from accredited labs
Results structured for fertility, endocrine, and telehealth workflows
The upper-arm capillary device collects a controlled blood sample without venous phlebotomy and has been validated against standard serum measurements. The collection method is fast, minimally invasive, and consistently rated as easy to use by patients.
Analytical performance
Across published trials, capillary blood showed 95–98% agreement with venous serum for key reproductive and metabolic hormones.
User acceptability
More than 90% of participants found the device easy to use, and over 85% preferred it to a traditional blood draw.
Why this matters?
Accurate at-home sampling expands access to clinically meaningful hormone testing and reduces dependence on in-clinic phlebotomy. High agreement with venous serum and low user-error rates reduce repeat sampling, streamline lab workflows, and improve adherence across fertility, endocrine, and telehealth pathways.

"I've been putting off hormone testing for ages because I hate finger prick tests, but Daye's new technology is fantastic."

‘’The pain is unpredictable and comes on quickly. I have passed out in public twice - each time while with a young child. It’s really scary.’’
