When it comes to your hormone health, peace of mind isn’t a “nice to have”—it’s everything.
Whether tracking ovulation, navigating hormone changes, or managing long-term cycle health, the quality of your data directly impacts the decisions you make and the confidence you feel in your body.
Mira uses fluorescent-based technology, the same method used in fertility clinics and medical labs. And in 2025, MiraLabs conducted an internal, controlled lab study¹ evaluating how precisely and reliably Mira Hormone Monitor with Ultra4 Wands measures key fertility hormones against certified reference standards.
Let's break down how this data was collected and analyzed, and why these findings are meaningful for anyone on a hormone health journey.
About this study
What was the goal?
We wanted to answer a simple question: How closely and consistently does Mira measure hormone levels when tested against known reference values?
We tested Mira under controlled lab conditions to evaluate how precisely and reliably it measures key fertility hormones.
What was the method?
We tested Mira Hormone Monitor with Ultra4 Wands in an internal, controlled laboratory setting.
- Urine samples were tested against certified commercial reference standards at known hormone concentrations.
- We measured 4 core hormones important for cycle and ovulation tracking: LH, FSH, E3G, and PdG.
- Each test was repeated multiple times to see how consistent the results were—not just once, but over and over again.
- We also checked how results held up under different lighting conditions and different phone cameras, reflecting real-world use.
What did we analyze?
Instead of just asking "does it detect hormones?" we focused on what really matters to users:
- Accuracy — how close Mira's result is to the true, known hormone level
- Consistency — whether you get the same result when testing the same sample repeatedly
- Sensitivity — Mira's ability to detect low hormone levels
- Stability — whether results hold steady across lighting, phone camera, or environment
Why does this matter for users?
Your insights and decisions depend on the numbers you get. If results vary too much, it becomes harder to understand your hormone patterns.
This study helps show that when you test with Mira, the data you see is reliable enough to make confident decisions.
High accuracy ¹—for data you can trust.
Accuracy is at the heart of what makes hormone data useful. It's not enough for a reading to move up or down in the right direction—the actual number needs to reflect what's really happening in your body. That's why our internal lab study put Mira through repeated testing against certified commercial reference standards, using known hormone concentrations as the benchmark for what a "correct" result should look like.
Across all four hormones we track—LH, FSH, PdG, and E3G—Mira's readings were evaluated for how closely they matched those established reference values. The study confirmed that Mira delivers high accuracy² across this full hormone panel, giving you numbers you can lean on rather than rough approximations.
Reliable ¹ results—for clearer trends, fewer surprises.
Reliability isn't just about getting an accurate result once—it's about getting a trustworthy result every time. Hormone levels shift daily, sometimes subtly, and a tracker that gives inconsistent readings from one test to the next can make it harder to understand your own patterns rather than easier.
To test this, our lab study didn't rely on a single measurement. Real urine samples were tested repeatedly, at multiple hormone concentrations, to see how closely each round of results lined up with the last. We looked specifically at linearity, precision, and reproducibility—essentially, whether Mira's results held steady and predictable across the full range of hormone levels, not just in ideal conditions. The study confirmed strong reliability² for Mira, meaning the trends you see over time reflect real changes in your body rather than noise in the test itself.
Sensitive ¹ detection—detect hormone shifts others miss.
Sensitivity comes down to a simple but important question: can a tracker pick up on hormone changes when levels are low, not just when they're already high and obvious? This matters most at the moments when precision counts—like catching the earliest signs of a hormone shift, rather than only confirming what's already underway.
To evaluate this, our study tested urine samples across a gradually increasing range of hormone concentrations, starting from very low levels, to identify the point at which Mira could reliably distinguish a genuine hormone signal from background noise. This was tested across LH, FSH, PdG, and E3G. The results confirmed that Mira is sensitive² enough to detect meaningful hormone changes even at low concentrations—the kind of subtle shifts that matter for confirming ovulation, tracking irregular cycles, or spotting early signs of a changing hormone pattern.
Why This Matters—Your Hormone Health Journey
A hormone tracker that's accurate, reliable, and sensitive doesn't just provide clearer numbers—it produces better understanding, and a clearer path to your goals.
High accuracy means you can trust what you're seeing. Skip the extra long wait for lab results, and bring hormone data to your doctor that is precise.
Strong reliability means those insights hold up day after day, cycle after cycle. Your patterns become clear, and so do your next steps to getting pregnant or understanding symptoms.
Good sensitivity means subtle hormone shifts aren't missed, even when levels are very high or low, or changing quickly. Built for any cycle, even if you have PCOS, hormonal imbalance and irregularities.
This kind of clarity supports more confident decisions, more informed conversations with healthcare providers, and a stronger sense of control over your hormone health journey—whether the goal is conception, cycle awareness, or better long-term hormonal wellbeing.
