Cardiolipins are substances present in outer cell membranes that regulate body's normal blood clot functions and other related activities. Cardiolipin antibodies are on the other hand produced by immune system that wrongly impairs these cardiolipins and thus hinder normal clotting mechanism.
Patients who are suffering from excessive blood clots are ordered to undergo this test. Women who have had some unexplained miscarriages can also be asked to get their cardiolipin antibody tested. Besides, a possibility of some infections lung disease, autoimmune diseases etc. require doctors to know about cardiolipin and related antibodies.
Undergoing this test involves collection of a small amount of blood. The procedure is carried out at a clinical facility where a health care provider will draw out the required amount of blood from your arms through a venipuncture. The upper part of your arm may be tied with an elastic band for easy punctures and thereby blood collection. No other preparation such as fasting is needed prior to sample collection. However, discussing medicines, health issues, and supplements you are taking is always suggested.
