Key Benefits
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.

The best wellbeing website…
The best health and wellbeing website in the UK. The range of products is fantastic, even on hard to reach USA products. I love the subscription service too. I'd be lost without this website.

Amazing!
Healf isn't just another wellbeing brand. They really get it. The products are fantastic, and the support is always so personal and genuine!
Janet
Great products, service, and customer support
Healf have a great range of wellbeing products not available elsewhere in the UK. They are competitively priced as one-off, but even better if you take up the 'subscription' which is super flexible too. I'd have no hesitation in recommending Healf.

I love Healf
It's the only place I get really decent health and wellbeing brands, particularly US brands. I've bought a Pvolve set, lots of Skinny Confidential stuff, Thorne supplements etc., the really great stuff that's impossible to get otherwise.
