Progesterone is a hormone produced primarily by the ovaries after ovulation. It prepares the uterine lining for pregnancy and supports early pregnancy. Testing progesterone levels can confirm ovulation, evaluate fertility, monitor hormone replacement therapy, and assess luteal phase deficiency. Levels vary significantly throughout the menstrual cycle.
Female reproductive hormone produced after ovulation. Used to confirm ovulation, monitor fertility treatments, evaluate luteal-phase defects, and track HRT.
Women with irregular cycles, infertility workup, suspected luteal-phase defect (early miscarriages), anyone on progesterone HRT, ovulation tracking for natural family planning.

What can throw off this result
Physician-reviewed “Before your test” pages — what each factor does, for how long, and what to do about it.
A Progesterone test costs $31.99 at TestWell — $37.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Ordered directly from the labs' own consumer sites, the same test lists at $89.00 at Quest Health and $89.00 at Labcorp OnDemand (list prices checked Sep 12, 2026). Hospital outpatient labs typically bill around $150.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible. Full cost breakdown →

Day 21 of a 28-day cycle (or ~7 days after ovulation in any cycle). Progesterone peaks mid-luteal phase; testing at the wrong time gives meaningless low results. Use ovulation kits or basal body temperature to time the draw if your cycle is irregular.
Above 10 ng/mL confirms ovulation occurred. Below 5 ng/mL suggests anovulation. 5-10 ng/mL is gray-zone and often indicates a luteal phase defect — sometimes treated with progesterone supplementation in fertility workups.
Progesterone stabilizes the uterine lining after ovulation and supports early pregnancy. Low luteal-phase progesterone is a recognized cause of recurrent early miscarriage and difficulty conceiving. Many fertility clinics supplement progesterone in IVF cycles for this reason.
