Mira Launches Cortisol Pattern™ Kit To Redefine Stress Tracking in Women's Health

The first at-home urine test built to track stress patterns over time using a biological signal instead of a wearable estimate

SAN FRANCISCO, Sept. 22, 2026 /PRNewswire/ -- Mira, a women's health technology company known for its at-home hormone tracking, today announced the launch of the Mira Cortisol Pattern™ Kit, a new at-home wellness kit that lets women track their stress patterns over time and view them alongside their cycle, hormones, and daily routine. The launch extends Mira's testing platform beyond hormone tracking into stress-pattern insight, using the same Mira Monitor and app that existing users already rely on.

Most consumer stress tools on the market today, including wearables, estimate stress indirectly, inferring it from signals like heart rate variability. The Mira Cortisol Pattern™ Kit takes a different technical approach: it measures urinary free cortisol, a hormone involved in the body's stress response, directly from a urine sample using the same lateral-flow testing format Mira already uses for hormone tracking.

Rather than a single snapshot test, the system is designed for repeated, longitudinal use, helping users understand their stress patterns over time, not just when they peak. With consistent testing, the Mira app builds a personal stress baseline in about a week, tailored by the individual user's own data, and then shows how new results compare with that baseline over time. For deeper insights into a user's daily rhythm, it's recommended to test twice a day – once in the morning and once in the evening – so they can see how their pattern shifts throughout the day and whether their body follows a typical wind-down pattern by evening. The Mira Cortisol Pattern™ Kit is designed to support general wellness awareness and stress-management habits. It is not intended to diagnose stress, an endocrine condition or any other medical condition.

For the more than 350,000 women who already use Mira to track their cycle and hormones, the Cortisol Pattern™ Kit adds a new layer of data to an existing routine. Powered by the Cortisol Pattern™ Wands, the Kit works with the Mira Monitor and app, meaning there's no second monitor, new sample type, or separate app to learn. By bringing stress-pattern and hormone data together in one app, Mira gives users a more complete picture of what's typical for their own body.

"The Cortisol Pattern™ Kit gives women a new way to understand their stress patterns over time, in the context of their own biology," said Sylvia Kang, Founder and CEO of Mira. "We built Mira to give women answers they had spent far too long searching for, beginning with the TTC journey and expanding into hormone and cycle tracking across life stages, including perimenopause. Now, we're taking Mira beyond reproductive health and into everyday wellness, bringing personalized stress-pattern tracking directly into women's homes."

How It Works:

1. Test: Dip a Cortisol Pattern™ Wand into a urine sample and insert it into the Mira Monitor.
2. Read: View the result in the Mira app within minutes.
3. Build a baseline: With about a week of consistent daily testing, the app establishes a personal stress-pattern baseline.
4. Track over time: Continue testing to see how stress patterns shift day to day and week to week. View those trends alongside cycle, hormone data and daily routine.
5. Build routines that work: the Mira App will also guide you throughout your journey and provide personalized lifestyle recommendations to support your well-being.

The Cortisol Pattern™ Kit and the Mira Cortisol Pattern™ Wands, available in 20- and 30-wand options, will be available for waitlist sign-ups starting September 22 at Shop.MiraCare.com.

Frequently Asked Questions
What is the Mira Cortisol Pattern™ Kit? It's an at-home testing kit that measures urinary free cortisol, a biological signal related to stress patterns, and turns repeated testing into an easy-to-understand view of how a person's stress patterns change over time.

Is this a medical device, and does it diagnose anything? No. Mira Cortisol Pattern™ Kit is intended for general wellness use consistent with the FDA's General Wellness Policy. It is not intended to diagnose, treat, cure, mitigate, or prevent any disease or medical condition. Consult your healthcare provider if you have any health concerns. 

Does cortisol equal stress? No. Cortisol is one hormone involved in the body's stress response; it is not a direct or complete measurement of stress. The Cortisol Pattern™ Kit tracks urinary free cortisol as a biological signal related to stress patterns.

How is this different from a wearable that estimates stress? Wearables typically estimate stress indirectly from signals like heart rate variability. The Cortisol Pattern™ Kit measures a biological signal, urinary free cortisol, directly from a urine sample, rather than inferring it from another metric.

How long does it take to see a personal baseline? With consistent daily testing, users can establish a personal stress-pattern baseline in about one week.

Do I need to test every day? Start with about a week of daily testing to build your personal baseline. After that, the Mira App will guide you to test a few times a week, so tracking stays simple and manageable.

Who is this designed for? The Cortisol Pattern™ Kit is designed to support women's well-being through every stage of their journey—from TTC and cycle tracking to hormonal changes, perimenopause, and beyond.

Whether they're focused on general wellness, better sleep, or navigating a high-stress lifestyle, the Kit helps women better understand their personal stress patterns – how they change from day to day, build over time, and shift from morning to evening. By viewing these patterns alongside their personal baseline, cycle, and daily activities, women can gain meaningful context and make informed lifestyle choices that support their everyday well-being.

Where can I buy it? Individuals can sign up for the waitlist starting September 22 at shop.miracare.com; wand refills are available to pre-order in 20-count and 30-count options.
