title: Endotoxin testing in blood.
abstract: A chromogenic assay is presented for the determination of endotoxin (LPS) in blood. The assay is based upon the LPS-dependent activation of Limulus amebocyte lysate (LAL), and the subsequent measurement of the activated enzyme with a chromogenic substrate. Handling and stability of the reagents, details of the assay method in tubes or microtiter-plates, recovery of LPS from spiked blood in platelet-rich plasma (PRP), platelet-poor plasma (PPP) and serum, as well as the possibility to store plasma samples will be discussed. A clinical evaluation of the assay is provided by S. van Deventer et al. in this volume.
