Endotoxin Testing is done in order that injectable preparations and medical equipment are absolutely free from pyrogens and Secure for human use. Pyrogens constitute a heterogeneous group of fever leading to substances which comprise both of those microbial and non-microbial substances.

If no anaerobic expansion of microorganisms is detected on Columbia agar, the product complies Using the test.
The looks of cherry purple colour ring along the facet in the test tube confirms the presence of E. coli.
