Frequently Asked Questions (FAQs) about Rapid Microbial Detection
-
When can I use a rapid microbial method to test?
Rapid microbial methods are an ideal solution wherever there is a benefit in obtaining a faster time-to-result than the traditional method. However, the potential applications for rapid microbiology are much wider and more ubiquitous than this. Most traditional methods, involving enumeration or visual confirmation of contamination can be replaced with a rapid detection method. These include purified water, water for injection (WFI), microbial limits, bioburden counts typically expected to be 0 CFU, critical in-process steps, and for incoming raw materials.
-
Do rapid methods need to be validated before I can use them? If so, how do I validate them?
Yes, implementing a rapid microbial method is an alternative method to your traditional, compendial method, which was validated prior to use as well. Historically, this task was considered very difficult and a barrier to entry for QC microbiology labs not familiar with alternative rapid methods. However, regulatory agencies and industry consortiums have responded and have published additional guidance documentation to assist implementation. Additionally, technology suppliers have been encouraged to do so as well. We can provide guidance on how to implement Celsis, as well as additional services and support when feasible.

-
What should I do if I get a positive result?
It is recommended that any detected microbial organisms be identified to the species level. The most reliable and accurate microbial identification method is DNA sequencing, which is the basis of our AccuGENX-ID® service. Another technology for identifying routine microbial samples is MALDI-TOF, which we offer as AccuPRO-ID®, or as Axcess®, our in-house solution. The key to the most accurate identification results is our proprietary validated microbial databases.
