Progesterone reference values table: normal ranges per cycle phase

A progesterone reference table helps you interpret your blood test results quickly. Progesterone varies significantly depending on your cycle phase.

Values per cycle phase (nmol/L)

Early follicular (day 1-7): 0.3-3. Pre-ovulatory (day 8-14): 0.3-5. Luteal (day 15-21): 10-80. Late luteal (day 22-28): 5-60. Conversion: 1 ng/mL = 3.18 nmol/L.

Values per life stage

Post-menopause: below 2 nmol/L. Early pregnancy (1st trimester): 30-90 nmol/L. Late pregnancy: up to 600 nmol/L.

How to interpret your results

Above 16 nmol/L in the luteal phase confirms ovulation. Above 30 nmol/L is strong confirmation. Below 10 nmol/L in the luteal phase may indicate an anovulatory cycle.

Frequently asked questions

Do I need to fast for a progesterone test?

No, fasting is not required. The timing in your cycle is much more important.
