The test protocols are based on guidelines delineated in USP Bacterial Endotoxins Test.Samples are assayed in quadruplicate against a five standard curve run in duplicate.

Removal of endotoxins requires a specialized filtration system, and they are not removed by 0.2um filters used to sterilize compounded medications.

Some typical sources of endotoxins are raw materials, water, instruments and reagents that are stored and used to compound, for example solutions used to adjust the p H of solution.

OUR METHODOLOGY DYNALABS employs the kinetic chromogenic and photometric quantitative testing methodologies, the kinetic-chromogenic, and the kinetic-turbidimetric methodologies.

Both technologies are sensitive down to 0.005 EU/m L.

United States Pharmacopoeia—National Formulary (USP-NF) entitled “USP Tests and Assays Chapter 797, Pharmaceutical Compounding, Sterile Preparations.” This chapter deals with new requirements for the compounding, preparation, and labeling of sterile drug preparations and applies to health care institutions, pharmacies, physician practices, and other facilities that prepare or compound sterile preparations (for example, intravenous solutions, eye drops)".

BACKGROUND Endotoxins are lipopolysaccharides (LPS) or lipooligosaccharides (LOS), found in the outer membrane of various Gram-negative bacteria.When injected into the body, they may cause anything from mild to severe inflammation, to in the most severe cases, septic shock.Presence of endotoxins in a compound is evidence of a current or previous contamination.Identification of contaminating organisms assists in understanding probable sources of the contamination, which will help in preventing or at least minimizing future contaminations.Identification is also important in determining the “usual or resident” microorganisms in the facility, so if new organisms are identified as part of an investigation, the source of the contamination may be new and/or not associated with the facility, people and/or processes.OUR METHODOLOGY DYNALABS employs a number of methodologies from gram staining and microscopic inspection, to amplification of the DNA from contaminating organism(s). FORMS TYPICALLY TESTED BACKGROUND Particles measured by this test are defined as insoluble, free floating substances that cannot be measured by chemical means.
