Progesterone level calculator

Progesterone levels during a woman’s menstrual cycle and during pregnancy.

Progesterone levels during menstrual cycle

Follicular phase – 1-1.5 ng/ml – 3.2-4.8 nmol/l
Lureal phase – 2-28 ng/ml – 6.4-89 nmol/l

Progesterone levels during pregnancy

1 trimester – 9-47 ng/ml – 28.5-150 nmol/l
2 trimester – 17-147 ng/ml – 54-468 nmol/l
3 trimester – 55-200 ng/ml – 175-636 nmol/l

Follicular phase

< 1.5 ng/mL ( 4.8 nmol/L ) - Normal level
> 1.5 ng/mL ( 4.8 nmol/L ) - High level

Luteal phase

< 10 ng/mL ( 32 nmol/L ) - Low level
> 10 ng/mL ( 32 nmol/L ) - Normal level

1 Trimester

< 5 ng/mL ( 16 nmol/L ) - Low level, non-viable pregnancy (100%)
< 10 ng/mL ( 32 nmol/L ) - Low level, abnormal pregnancy
< 25 ng/mL ( 80 nmol/L ) - equivocal range
> 25 ng/mL ( 80 nmol/L ) - Normal level, viable intrauterine pregnancies (98%)

2 Trimester

< 40 ng/mL ( 125 nmol/L ) - Low level
> 40 ng/mL ( 125 nmol/L ) - Normal level
