Grip testing instructions

Before you start, read the instructions all the way through the end! The full process takes about 30 minutes, so make sure you've got the time.

  • Take the test in the morning on an empty stomach, make sure you haven't eaten anything for 8 hours - clear fluids are fine.

  • If you are having trouble pricking/collecting blood, or want some company, WhatsApp us at +31 6 57625478. We are happy to walk you through it live. We are available M to F 10:00 to 19:00, outside of that, just give us a 12-hour heads up.

I don't use hormonal contraceptives (e.g. condoms, copper IUD, no birth control)

Take the test on the 3rd day of your menstrual cycle. Day 1 of your cycle is the first day of full flow (i.e. you need to use pads/tampons) – not the first day of spotting.

I'm on birth control (e.g. the pill, hormonal IUD, implant)

​You can take the test any cycle day, we won’t be testing hormones related to ovulation.

Ok! Let's do it
