WebAug 8, 2024 · The kinetic-turbidimetric method is a quantitative LAL test. It is more sensitive than the gel-clot method, with a detection range as low as 0.001 EU/mL. The same PYROSTAR ES-F Series may be used for the gel-clot or the kinetic-turbidimetric assay. The principle behind this method is that the cloudiness (turbidity) of the test … Webunequivocally recognized as the most sensitive method available for the detection of endotoxins. In the 50 years since the discovery of LAL, approximately 70 million bacterial endotoxin tests have been performed each year, and there have been no FDA-confirmed pyrogenic outbreaks due to an LAL false-negative result.

WebAug 28, 2014 · The LAL sensitivity is assessed by performing a 2-fold dilution series. The RSE used to characterize the lysate is not readily available to all test laboratories because of its rarity and cost. Laboratories normally use Control Standard Endotoxin (CSE).
