WHY YOU NEED IT
Why Compendial Sterility Testing Matters
The accepted gold standard
USP <71> is the compendial reference for sterility — a passing result is the universally recognized basis for releasing a sterile product.
Broad organism recovery
A 14-day incubation across two growth media is designed to recover slow-growing bacteria and fungi that faster screens can miss.
What inspectors expect
For products and programs that require the compendial method, <71> is the test regulators and inspectors look for.
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 35 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 35 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).
Usually [X] vials per timepoint
TECHNOLOGY
Filter, culture, and watch for 14 days.
01
Membrane filtration
Product is filtered through a sterilizing-grade membrane that captures any microorganisms, then rinsed free of residual product.
02
Dual-media incubation
The membrane is cultured in both fluid thioglycollate and soybean–casein digest media to recover aerobes, anaerobes, and fungi.
03
14-day readout
Cultures are watched for 14 days; any growth is investigated and identified before a result is issued.
