The LAL Test, or Limulus Amebocyte Lysate Test, is a laboratory procedure used to detect the presence of bacterial endotoxins in medical devices, pharmaceuticals, and other products. It utilizes a substance derived from the blood of the horseshoe crab, which clots in the presence of endotoxins, indicating contamination. This test is crucial for ensuring the safety and sterility of products that come into contact with the human body. The LAL Test is often preferred over traditional methods because it is sensitive, quick, and can detect very low levels of endotoxins, helping to prevent potential infections in patients.
