About this test

Cardiolipin antibodies are proteins your immune system can produce against cardiolipin, a lipid found in cell membranes. Raised IgG or IgM levels are associated with an increased risk of abnormal blood clotting and are one of the markers used when investigating unexplained blood clots, recurrent pregnancy loss or suspected antiphospholipid syndrome, usually alongside other clinical information rather than on their own.

This is the only cardiolipin antibody test in our Better2Know catalogue, so there is no direct in-house peer to measure its price or depth against. At £195 for two markers, it sits well above the median price of the wider set of inflammation and autoimmunity tests we track, which tend to include more markers for less.

The test scores well for clinical depth, since two related antibody markers place it toward the upper end of the inflammation tests we track, and reasonably for collection convenience given the option of a home nurse visit instead of a clinic trip. It scores poorly on value for money for the reasons above, and, in line with the rest of Better2Know's catalogue in this sheet, on results and follow-up, because your result is not reviewed by a doctor as standard. Better2Know is CQC registered, rated 4.2 on Trustpilot from 775 reviews, and has traded since 2008.

Who is it for?

This test may be relevant if you or your doctor are investigating an unexplained blood clot, recurrent miscarriage, or a suspected autoimmune condition such as lupus, where cardiolipin antibodies form part of the wider clinical picture. It is not a stand-alone answer, and results are best interpreted alongside your other symptoms and test results by a doctor.

We do not have another Better2Know test measuring cardiolipin antibodies to compare this one against on price or depth. If you have symptoms such as leg swelling, chest pain or repeated pregnancy loss, see a GP rather than relying on this test alone.

How it works

A trained healthcare professional takes a venous blood sample, either at a Better2Know clinic or during a home nurse visit. Your sample is analysed for IgG and IgM cardiolipin antibodies, with results typically available within two days, accessible through Better2Know's secure online patient area. Results are not reviewed by a doctor as standard.

Pros & cons

Pros

  • Covers both IgG and IgM cardiolipin antibodies in one test.
  • A home nurse visit is offered instead of a clinic appointment.
  • Results are typically available within two days.

Cons

  • £195 sits well above the median price of similar inflammation tests we track.
  • No comparable Better2Know test to check this price against.
  • Results are not reviewed by a doctor as standard.
  • Requires a venous blood draw rather than a home finger-prick.

Our editorial score

Compare Health Test Score Two-marker clotting antibody test, priced above typical
Editorial confidence: 9.0/10

This test measures IgG and IgM cardiolipin antibodies from a venous blood sample, taken at a clinic or during a home nurse visit. At £195 it costs well above the median for the inflammation and autoimmunity tests we track, though it does cover two related antibody markers rather than one. We have no other Better2Know test in this group to compare it against directly, so the price sits on its own.

Score breakdown

  • Clarity and documentation 9.0/10

    The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.

  • Clinical depth 8.6/10

    2 biomarkers, placing it in the 69th percentile of inflammation tests we track.

  • Collection convenience 6.0/10

    Requires a venous draw at a clinic; a home nurse visit is offered; results in around 2 days, well ahead of the inflammation norm of 4.

  • Results and follow-up 3.0/10

    Results are not doctor-reviewed and no consultation is included; the provider does not describe the report format.

  • Trust signals 6.5/10

  • Value for money 2.0/10

    £195.00 against a median of £89.00 for the 30 similarly sized inflammation tests we track (+119%).
