Fundamentals of Endotoxin Testing for Medical Device Manufacturers are Detailed in New Technical Brief

AGAWAM, MASS. — The fundamentals of endotoxin testing for medical device manufacturers — from definition to assay acceptance criteria —are detailed in new technical brief available from Microtest Laboratories.

Bacterial endotoxins cause fever, septic shock, and other disease symptoms — and thus attract considerable regulatory scrutiny from such organizations as the U.S. Food & Drug Administration (FDA) and the United States Pharmacopeial Convention. Regulations require that devices that contact circulating blood or cerebrospinal fluid, or are used with intraocular products or in vitro fertilization procedures, are required to be endotoxin-free.

“The Fundamentals of Endotoxin Testing,” available for download at http://microtestlabs.com/endotoxin-testing, is a step-by-step information resource for medical device manufacturers discussing and detailing the:

• Definition of endotoxins;
• Various tests used for their detection;
• Use of depyrogenation and other ways to remove endotoxins;
• Types of devices that should be tested;
• Preparation and testing of samples;
• Options for sampling containers;
• Acceptance criteria for each of the assays; and
• Sources of official information, reference, and guidance.

“The Fundamentals of Endotoxin Testing” is authored by Steven Richter, Ph.D., said Steven Richter, Ph.D., president and scientific director of Microtest Laboratories — and a former FDA official.

Disinfectant Qualifications in Pharmaceutical Manufacturing Environments is Focus of White Paper

AGAWAM, MASS. – May 12, 2014 – A white paper outlining the six steps that pharmaceutical and medical device manufacturers must employ to qualify disinfectants used in their environmental cleaning processes is available from Microtest Laboratories. It is available for download from http://microtestlabs.com/6stepspaper-disinfectant-qualification.

“Sterile pharmaceutical and medical device manufacturing environments require an effective cleaning and disinfection program to maintain aseptic conditions and prevent the microbial contamination of the product. The qualification of the chemical disinfectants used in these environments is extremely important, yet it is often overlooked,” stated Deborah Ensign, supervisor, R&D of Microtest Laboratories, in the new white paper, “Six Steps to Qualifying Disinfectants.”

In fact, “disinfectant qualifications require more planning, time, and resources than many companies realize,” she said.

“Any time a new disinfectant is introduced into the cleaning process within the facility, a qualification should be performed. From start to finish, a disinfectant qualification can require from 2 to 12 months.

“The timeline for a disinfectant qualification will depend on a number of variables, including the number of disinfectants and challenge organisms being tested as well as the number of surfaces (for the coupon method) being evaluated,” Ensign noted.

“The bottom line is that no matter whether the disinfectant qualification is performed internally — or by an outside testing laboratory — these six steps must be addressed,” she warned.
