To be “awake” means that you are fully conscious, you know who and where you are; you are in a state that is clearly different from when you were sleeping even though you may still feel tired. If you wake up during the middle of the night and plan to go back to sleep, do not begin sampling. Please only begin when you are awake for the final time before you plan to get up for the day.
It is ok if you struggled falling asleep; it is above all the hours before waking up that concern us. If you had an uneasy wake-up and do not feel you have a clear time point for when you went from “asleep to awake”), it is better to defer the testing to a different day.
If more than 5 minutes pass after you wake up before you give your sample, please defer to a different day.
The hormone of interest will keep stable in saliva for up to a week at room temperature. We recommend you put the samples in the fridge (especially during the warm season), until they are shipped (maximum 24 hours later). Full instructions are given inside the pack.
We have allowed a 'back' function in the questionnaire. There is also a full 'reset' function in the questionnaire provided you have not completed it yet. If for whatever reason you need to void your results once you have completed and submitted your results, please contact Persometrics so we can reset the questionnaire for you.
We currently deliver to Switzerland, Norway, Liechenstein and most of the European Union, reliability of postal service being the main factor here. See map below.
We keep packaging to a minimum. The fact that we do not use bulky packaging not only helps save the environment in line with our "Reduce-Reuse-Recycle-Offset" policy, but also means that delivery costs can be kept down. Please do bare this in mind also when you open your parcel, which may not include as much wrapping as you are used to. It is safe for transport but does not include more paper, carton and plastic than is necessary.
