Antiphospholipid (APL) testing is a diagnostic procedure that determines the presence of antiphospholipid antibodies in the blood. Human body have an advanced immune system that creates antibodies (proteins) to fight a variety of infections and disorders. If left untreated, our immune system may wrongly target our phospholipids, resulting in blood clots and other health concerns. Phospholipids are a kind of lipid (fat) present in blood arteries and blood cells that aid in cell activity and blood coagulation.
What is the use of the APL test?
The antiphospholipid (APL) test is used to identify phospholipid antibodies in the blood. Phospholipid antibodies are seen in autoimmune illnesses such as rheumatoid arthritis, systemic lupus erythematosus (SLE), and multiple sclerosis. It is also used to detect recurring and unusual blood clots, miscarriages, and thrombocytopenia (low platelet count).
Why is the need for an APL test?
An APL test is recommended by a doctor if a patient has a history of miscarriages, atypical blood clots, or a family history of autoimmune illnesses. It is also used to detect antiphospholipid syndrome, a medical disorder in which your immune system damages phospholipids in your body, causing blood clots to develop.
What happens during an APL test?
A healthcare provider takes a blood sample by inserting a small and thin needle through the vein in your arm. Once the blood sample is taken, your healthcare provider cleans the injection site and puts on a bandaid on it to stop blood flow.
Understanding the Anti Phospholipid (APL) test findings
A negative APL test result indicates that you do not have any phospholipid antibodies. If your findings show low to moderate amounts, it means you have phospholipid antibodies, which may have formed as a result of aging, illness, or certain drugs.
