Ultra4 Kit is a 4-in-1 fertility test kit that measures FSH, LH, E3G and PdG to provide a more complete picture of hormone changes throughout the menstrual cycle. Powered by Mira's fluorescent technology, it delivers lab-grade accuracy from the comfort of home, helping take the guesswork out of fertility tracking.

By monitoring hormone levels in real time, the kit helps identify the fertile window and confirm ovulation day. It also provides insight into early follicle development before the LH surge, helping users better understand their cycle and recognise when ovulation may not be progressing as expected.

Each test delivers results in just 16 minutes and offers 2.5× improved LH sensitivity for more precise ovulation detection. The ergonomic wand design also makes testing easier and more comfortable to perform at home.

Please Note: Ultra4 Kit is intended for hormone monitoring and menstrual cycle tracking. It is not designed to diagnose, screen for or indicate ovarian function, egg supply or any medical condition.

Why Mira is Healf

Mira uses fluorescent lab technology, the same type of technology fertility clinics use, to measure hormone levels at home with 99.5% lab-grade accuracy. Unlike traditional ovulation kits that show vague lines or phone trackers that rely on estimates, Mira provides real hormone concentration results in real time. It tracks subtle hormone shifts across the cycle and offers data that is 7× more accurate than other quantitative at-home trackers. This gives you clearer insight into your fertile window and ovulation patterns, helping you make more informed decisions without blood tests, clinic visits or guesswork.

Mira was co-founded by biomedical engineer Sylvia Kang, driven by her passion to bring scientific clarity to women’s hormone health. Recognising the lack of accessible tools, she developed a medical-grade, at-home hormone tracking system powered by advanced fluorescent technology. Mira combines precise hormone measurement with AI trained on millions of tests, delivering personalised insights through its app. Each product focuses on accuracy, data depth, and ease of use, helping users understand changes across their cycle. With Mira, you can track your hormones with confidence and make more informed decisions about your health.
