A single-marker blood test measuring progesterone, typically taken on day 21 of your cycle to help assess whether ovulation has occurred.
1 biomarker as listed by Forth.
Progesterone rises after ovulation, so testing on day 21 of a typical cycle is commonly used to help assess whether ovulation has taken place. This test measures progesterone alone, giving a single reading rather than a wider hormone picture.
Among the six progesterone tests we track, this sits close to the middle of the price range: £44 against a group median of £45. Medichecks' Ovulation Progesterone Blood Test and London Medical Laboratory's Progesterone test are both cheaper at £39, while Blue Horizon Medicals charges £64.25 and Better2Know's options run to £175 and £195. All measure the same single marker.
value for money is close to average, only 2% below the group median. Collection is flexible across four methods, and results are reviewed by a doctor within 2 days. If you want a wider female hormone picture rather than a single day-21 reading, Forth's own Perimenopause test covers progesterone alongside three other hormones.
This suits you if you specifically want a day-21 progesterone check, for example to help assess ovulation as part of fertility tracking. If price is the main factor, Medichecks' Ovulation Progesterone Blood Test or London Medical Laboratory's Progesterone test cover the same single marker for £39. If you want a wider hormone picture, Forth's Perimenopause test covers progesterone alongside LH, FSH and oestradiol.
Collect your sample using an at-home finger-prick kit, Forth's AutoDraw device, a home nurse visit, or a venous draw at a partner clinic, timed to day 21 of your cycle. The lab measures your progesterone level, and a doctor reviews the result before it is released. Results are typically available within 2 days.
Taken on day 21 of your cycle, this single-marker progesterone test costs £44, close to the £45 median across six progesterone tests we compare.
