 Despite the fact that this steerage isn't intended to deal with biological assays, most of the concepts during the steerage are applicable to bacterial endotoxins testing. We update direction paperwork periodically. To make sure you have The newest Variation of the advice, Examine the FDA Prescription drugs steerage Web content at

Reduced Endotoxin Recovery (LER) is really a controversial subject that has been circulating all through the endotoxin detection here Neighborhood because 2013.

Some solution forms should not be pooled. Two examples are drug products that have an Preliminary lower MVD (see dialogue above of “adjusted MVD”) and products that are manufactured like a suspension, for the reason that sample aliquot homogeneity might present considerable interference troubles.
