Limulus Amebocyte Lysate (LAL) Testing
The Limulus Amebocyte Lysate (LAL) test is an in vitro assay used for detection and quantitation of bacterial endotoxin. LAL is an aqueous extract of the blood cells of horseshoe crabs which forms a clot or change in color, depending on the technique, in the presence of bacterial endotoxin. Validated test methods include both the gel clot and chromogenic methods. Inhibition / enhancement testing is performed prior to routine LAL testing to demonstrate validity of the LAL test.
