This egg-shaped device seeks to simplify hormone tracking using urine.
Your urine can reveal a lot about your reproductive health hormones, but traditional at-home testing can be a hassle, often requiring you to collect samples and send them off to labs. Enter Mira, a health startup aiming to streamline this process with its $249 Ultra4 Hormone Monitor.
The Ultra4 is designed to provide accurate hormone testing right at home. It consists of two main components: the Hormone Monitor, a sleek, egg-shaped device that analyzes your test results, and the Ultra4 Wand, a test stick you use by urinating on it. This wand tests for four key reproductive hormones: follicle stimulating hormone (FSH), luteinizing hormone (LH), estrone-3-glucuronide (E3G), and pregnanediol 3-glucuronide (PdG).
By measuring these hormones simultaneously, users can track fertility and gain insights into conditions like polycystic ovary syndrome (PCOS), premenstrual dysphoric disorder (PMDD), perimenopause, menopause, and even metabolic health. Regular at-home testing aims to help you tailor treatments for these conditions and observe trends in your hormone levels over time.
“The goal is to empower women to take charge of their health,” says Mira’s CEO and cofounder, Sylvia Kang. She notes that when she started Mira in 2018, at-home hormone testing was virtually nonexistent. “I saw many friends struggling to conceive later in life, and they faced numerous challenges without understanding what was wrong. The only options available were ovulation kits or basal body thermometers, neither of which offered lab-grade accuracy or real insights into their bodies.”
Fast forward to today, and the conversation around “hormone balancing” has gained traction, even if the information shared by influencers isn’t always accurate. Mira has been around for nearly a decade, and the Ultra4 kit was softly launched in late August, with wider availability announced at CES 2026. As someone with PCOS and approaching perimenopause, I was eager to try out the device.
Using the Ultra4 is straightforward. You start by completing a detailed survey in the Mira app about what you want to learn (like fertility windows or insights into irregular cycles). Then, you fill a collapsible silicone cup with urine, insert the test wand, and after 15 seconds, place it into the analyzer. In about 16 minutes, you’ll see your results on the device and in the app. Based on your goals, the app will create a personalized testing schedule.
While it’s too soon for me to draw conclusions from my results, a single test can provide insights into cycle health, egg reserve, and potential causes of irregular cycles or hormonal issues. My custom plan indicates that I’ll need to test for five consecutive days over two cycles to assess signs of perimenopause. This device is designed for long-term use to establish a hormonal baseline. The app also offers explanations of each hormone’s role in the body and what high or low levels might indicate.
It’s important to note that Mira is not a contraceptive tool; it falls within the wellness category. The device is classified as a Class I device by the FDA, meaning it’s considered low-risk and doesn’t require extensive regulatory scrutiny.
Kang mentions that fertility isn’t the sole focus for users anymore. “Currently, 40 percent of our users are not trying to conceive. They’re interested in menopause, PCOS, and general hormone management,” she explains. The aim is to provide data that helps users understand their health better. For instance, if a user notices specific symptoms like headaches or nausea coinciding with hormone spikes, they can discuss these patterns with their doctor for tailored treatment.
Looking ahead, Kang envisions expanding Mira’s capabilities to analyze other biological fluids like blood and saliva for hormonal insights. The ultimate goal is to broaden the focus from reproductive health to overall longevity and preventive health, as early research suggests links between certain hormones and metabolic health.
For now, the price remains a significant hurdle. The Ultra4 Hormone Kit starts at $249, with replacement wand packs around $99 and the analyzer priced at $149. However, this aligns with the growing trend in health tech. The COVID-19 pandemic has increased the popularity and accessibility of at-home testing, and hormone testing technology was highlighted at last year’s CES. Companies like Withings, Oura, and Whoop are also exploring blood and urine testing to promote healthy aging.
