The Mira App: How to read PdG results?
First things first: what is PdG?
Pregnanediol glucuronide (PdG) is a urine metabolite of progesterone. It is produced in the corpus luteum in the ovaries after ovulation occurs.
Simply put: you need to monitor PdG in order to confirm that ovulation has actually occurred in any given cycle.
Are my PdG levels normal?
When testing with Mira, PdG levels are typically around 5 ug/mL during the follicular phase (i.e. in the first half of the cycle before ovulation). After ovulation, PdG levels can be between 5 to 25 ug/mL.
Average Ranges for PDG hormone are:
|Follicular phase||Ovulatory phase||Luteal phase|
|1-5 ug/mL||3-7.5 ug/mL||5-25 ug/mL|
However, PdG levels vary depending on the person. Due to individual differences and hormone changes, we suggest you pay more attention to the hormone pattern than the absolute value.
When you see a rapid surge of PdG for three consecutive days, it means that ovulation has occurred.
Good to know: a slight increase of PdG may be noticed in some cases 2-3 days before ovulation, but it doesn’t mean that ovulation will definitely happen.
- If conception does not occur, PdG tends to peak around 6-8 days after ovulation. It then decreases and your period begins.
- If conception does occur, PdG levels continue to rise in order to maintain a healthy pregnancy. PdG levels will not decline after peaking, and levels will rise beyond what is detectable by Mira wands. It’s important to note that these wands are not designed for pregnancy monitoring.
In the Mira App, you can visually compare your charts with other people’s average charts – this can help you see if your chart is in range or out of range.
- How? Go to the Charts page. Click on the ‘PdG’ name of the hormone on the top of the screen. Choose who you want to compare your charts with: Healthy users or Pregnant
Why do I need to test PdG the whole cycle?
The algorithms in the Mira App do not use a fixed threshold.
To put it simply:
- We do not say: “Ovulation happened, because your PdG is 10 ug/ml”
- We do say: “Ovulation happened, because we see it in your individual pattern that is based on your PdG curve during your unique cycle”
The more recommended days you test, the more our AI learns about your personal hormone map – what is normal and typical for your body, not for an average person. The app will utilize this data to better predict and confirm ovulation for future cycles.
