What is Cardiolipin Antibodies Blood Test? (Background Information)
- Cardiolipin antibodies are bodily defense proteins that mistakenly target host phospholipids. They are one of the several antiphospholipid antibodies, responsible for causing antiphospholipid syndrome (APS)
- Phospholipids are a type of fat molecules comprising the membranes of cells. They serve crucial roles in cell signaling, transport, adhesion, and other functions
- Cardiolipin antibodies target the phospholipids of bodily tissues. This occurs mostly in the inner lining of blood vessels, involving cells, called endothelial cells
- When cardiolipin antibodies recognize the phospholipids of endothelial cells along the inside of blood vessels, they attach to them. The resulting coagulated mass disrupts the intricate balance, between the pro-coagulating and anti-coagulating factors present in blood
- Consequently, cardiolipin antibodies increase the likelihood of a blood clot forming inside blood vessels. This extremely dangerous condition is known as thrombosis
- A thrombotic blood clot is dangerous, because it impedes the flow of blood. Instead of the flow being smooth and “laminar,” it becomes turbid. This diminishes the blood’s capacity to transport vital nutrients, through the body and remove wastes
- More importantly, the thrombotic blood clots can detach themselves and result in an embolus. An embolus is a freely floating blood clot, capable of lodging into vital blood vessels and blocking blood flow
- Tissues deprived of oxygen have a limited capacity to function; in the case of the heart and lungs, the results can be deadly
- The Cardiolipin Antibodies Blood Test is a test to detect the presence of cardiolipin antibodies in blood. It is used to diagnose antiphospholipid antibody syndrome

The laboratory test results are NOT to be interpreted as results of a "stand-alone" test. The test results have to be interpreted after correlating with suitable clinical findings and additional supplemental tests/information. Your healthcare providers will explain the meaning of your tests results, based on the overall clinical scenario.
Additional and Relevant Useful Information:
- Certain factors may interfere with the results of the Cardiolipin Antibodies Blood Test. These include infections, certain cancers, and old age
Certain medications that you may be currently taking may influence the outcome of the test. Hence, it is important to inform your healthcare provider, the complete list of medications (including any herbal supplements) you are currently taking. This will help the healthcare provider interpret your test results more accurately and avoid unnecessary chances of a misdiagnosis.
