[Limulus test using a chromogenic method: application to the control of pyrogens in blood derivatives].

We report here the application of the LAL Test to a chromogenic substrate to detect endotoxins in Human Blood Products. In order to reduce the cost, we used a microplate procedure with the Multiskan Reader. Quantitative results in the range of 0,01 to 0,1 ng/ml allowed for a good correlation with the Rabbit Pyrogen test.
