A single-marker blood test for progesterone, commonly taken around day 21 of a cycle to check whether ovulation has occurred. Suits anyone tracking ovulation or fertility at home.
1 biomarker as listed by Medichecks.
This test measures a single marker, progesterone, which rises after ovulation. It is commonly taken around day 21 of a 28-day cycle to check whether progesterone has risen as expected in that phase of the cycle.
Within its comparison group of six progesterone tests, this is tied for the cheapest alongside London Medical Laboratory, both at £39, and is cheaper than Forth (£44), Randox Health (£45) and Blue Horizon Medicals (£64.25). Better2Know's equivalent tests are considerably more expensive, at £175 and £195. Because every provider in this group measures the same single marker, price and collection convenience are the main things that separate them.
It scores well on collection convenience because you can do it at home with a finger-prick kit, or opt for a clinic visit or home nurse visit if you prefer, with results back in 2 days. It also scores well on trust signals, reflecting Medichecks' Trustpilot rating and accredited partner labs, and results come with a doctor's comment.
This suits anyone tracking ovulation or an early fertility work-up who wants a low-cost, single-marker check they can do at home. Because it measures progesterone only, it will not suit anyone wanting a wider hormone picture in one test.
On price it is matched only by London Medical Laboratory's equivalent test, also £39; if you would rather test at home with no clinic option needed, this or the London Medical Laboratory test are the cheapest routes, while Forth (£44) and Randox Health (£45) cost slightly more for the same single marker.
You can collect a sample at home with a finger-prick kit, or have a venous blood draw at an in-store clinic or via a home nurse visit. Medichecks states results are returned within 2 days, with a doctor's comment included as standard.
At £39, this single-marker test matches London Medical Laboratory as the cheapest progesterone test we track and undercuts Forth (£44) and Randox Health (£45). It measures only progesterone, taken around day 21 of a 28-day cycle, and can be done with an at-home finger-prick kit or a clinic visit, with results in 2 days and a doctor's comment included.
