About this test

CA 125 is a protein found on the surface of most, though not all, ovarian cancer cells, which is why it is used as a tumour marker in specific circumstances. As the provider notes, a raised level does not always mean cancer is present, since it can also be produced by normal tissue and raised by conditions such as menstruation, pregnancy or pelvic inflammatory disease, so results need interpreting alongside your symptoms and history by a GP.

As a single-marker test it sits toward the lower end of the cancer screening tests we track for depth, reflecting its narrow, specific purpose. It scores well on price, below the median for similarly sized cancer screening tests we track, and very well on collection convenience, since you can test at home, at a clinic, or via a nurse visit, with results back in around a day. The listing is detailed, with a thorough description, the biomarker, sample type, turnaround and collection options all clearly stated.

Blue Horizon Medicals has traded since 2009 and uses UKAS ISO 15189 partner labs, with a Trustpilot score of 4.2 from 395 reviews. A doctor reviews your result before it is released.

Who is it for?

This may be relevant if a clinician has suggested monitoring CA 125 as one part of a wider assessment, or if you want a marker commonly associated with ovarian cancer risk factors to discuss with your GP. It is not designed to confirm or exclude cancer on its own, and a raised result can have several non-cancerous causes, so any concerning symptoms should be discussed with a GP rather than relying on this test alone. We do not have peer tests logged in this comparison group, so we cannot compare it directly with other providers' CA 125 tests.

How it works

You can collect a sample at home using a finger-prick kit or Tasso autodraw device, or have a venous draw taken at a clinic or during a home nurse visit. The lab measures your CA 125 level, and a doctor reviews the result before it is released to you, typically within around 1 day.

Pros & cons

Pros

  • Flexible collection: home finger-prick, Tasso device, clinic, or nurse visit.
  • Below the median price for similarly sized cancer screening tests we track.
  • Turnaround of around 1 day.
  • A doctor reviews the result before you see it.

Cons

  • A raised result can be caused by several non-cancerous conditions, so it is not conclusive alone.
  • Single marker, so it will not give a broader cancer risk picture.
