Here are steps to calculate the Progesterone to Estrogen Ratio.
- Progesterone: 1 ng/mL = 3.180547 nmol/L
- Estradiol: 1 pg/mL = 3.6713 pmol/L
After bringing the hormone concentrations to the same unit of measure, the calculation of the P/E2 ratio itself is straightforward:
Ratio = progesterone / estradiol
The table below summarises the normal range values for the Pg/E2 ratio and the parameters involved.
Parameter | Normal range values | |
Progesterone (ng/mL) | Pre-ovulation: <0.89 Ovulation: ≤ 12 Post-ovulation: 1.8-24 |
1st trimester: 11-44 2nd trimester: 25-83 3rd trimester: 58-214 |
Estradiol (pg/mL) | Premenopausal women: 30-400 Postmenopausal women: 0-30 |
|
Pg/E2 | 100-500 if E2 is within the normal luteal phase range (i.e. 1.3-3.3 pg/mL in saliva or 43-180 pg/mL in blood spot) |
Let's say a woman's blood test shows the following hormone levels:
- Estradiol: 100 pg/mL
- Progesterone: 10 ng/mL
To calculate the Progesterone to Estrogen ratio, you need to first convert the units of measurement for each hormone to the same units. In this example, let's convert the estradiol level from pg/mL to ng/mL:
Estradiol: 100 pg/mL = 0.1 ng/mL
Now that both hormones are in ng/mL, you can calculate the Progesterone to Estrogen ratio by dividing the progesterone level by the estradiol level:
- Progesterone to Estrogen ratio = Progesterone level / Estradiol level
- Progesterone to Estrogen ratio = 10 ng/mL / 0.1 ng/mL
- Progesterone to Estrogen ratio = 100:1
In this example, the Progesterone to Estrogen ratio is 100:1.
