NOW OFFERING
Rapid Sterility Testing
Rapid sterility testing validated under USP <1223> — for compounding pharmacies that can’t afford a two-week wait on batch release.
View Testing Services
Compendial standard this method is validated to.
Business days from sample receipt to report.
Compounded formulations supported to date.


WHY YOU NEED IT
Why Rapid Sterility Testing Matters
Catch contamination fast
Viable bacteria or fungi in a sterile preparation can cause life-threatening bloodstream infections — a rapid method flags them in about a day instead of two weeks.
Release within the BUD
Compounded sterile preparations often carry short beyond-use dates; results in ~1–2 days let you release product while it's still usable.
Fast, but still validated
Rapid microbial methods are held to USP <1223> equivalence criteria, so quicker results detect the same contamination the compendial test would.
OUR PROCESS
How we run this test for you
Method Suitability
Proving the method first
Before any lot release, we validate that the test method performs reliably for your product — the compliance step that comes first.
Typically 40 vials per study
Lot Release
Releasing every batch
Our core service — we run the test on each lot so you can release the batch to patients with confidence.
Typically 10 vials per lot
Stability Studies
Across your stability timeline
The same test run at each stability timepoint — for example, to support a longer beyond-use date (BUD).
40 vials for MST, then 10 vials per timepoint
TECHNOLOGY
We detect what's alive at the molecular level.

CATEGORY 2
CATEGORY 3
These studies generate the stability data required to qualify for the extended beyond-use dates that USP <797> permits for Category 2 and Category 3 CSPs — going well beyond the default short-dating limits.
