What is Antiphospholipid (APL) Test?
Antiphospholipid (APL test) is a medical test conducted to check the presence of antiphospholipid antibodies in the blood. Our body has a well-developed immune system that produces antibodies (proteins) to fight against a host of infections and diseases. Sometimes, our immune system mistakenly attacks our phospholipids, resulting in blood clots and several other health complications if left untreated. Phospholipids are a class of lipids (fats) found in the blood vessels and blood cells that play a significant role in cell functioning and blood clotting.
