It was a pretty big shock when I first got my results, and I’m glad that it was possible to discuss them over the phone pretty much instantly.  I’d highly recommend other young women to do the Grip test.

The Grip test has calmed my worries, and given me a better idea of whether I am okay to wait a bit longer, or if I should start trying to get pregnant as soon as possible.

I strongly believe that you can live your best life best when you know more about yourself. I feel so much more at ease now I don’t have to go through life thinking ‘what if’.

How Grip works

You can take the test from the comfort of your home

Get the kit

Answer a few questions, we'll customize your test based on your birth control.

So yes, you can take the test if you're on birth control.

Collect your blood

Prick your finger, collect about 10 drops (0.5ml) of blood, and pop your sample in the mail. That's it!

Lab analysis

Our lab, the same ones fertility clinics use, analyses your blood sample. 

Our lab is ISO15189 certified, the highest possible medical certification in Europe.

Your plan of action

Your results are just the start. Most fertility related issues are easily treatable, as long as you have time. Our doctors will make a (free) plan with you, and you can ask all your questions in our closed chat group.

How we protect your data.

We understand how sensitive your information is, and we work very hard to keep everything as safe as possible. The lab uploads your results to a special medical cloud, and the only way that we can see your report is through 2-factor authentication. Only medical professionals have access to your report.


We are GDPR compliant, which means that we won't store any of your data unless you give us explicit permission to do that. Most women want us to store their information so that if you test again next year, we can easily compare your results.


We ask everyone to opt in to giving us an anonymised version of your results for fertility research, but if you don't want to participate, you, of course, don't have to.
