Numerous parenteral drug goods can be employed for that LAL test following dilution with endotoxin-cost-free distilled h2o or an aqueous Resolution over the ailment that dilutions not exceed the maximum valid dilution. In 1973, Nachum et al. evaluated cerebrospinal fluid (CSF), that has really low protein articles when compared with blood, utilizing the LAL test as a potential Software to detect GNB meningitis.
