How long does testing take?
Normal 4X and 8X turnaround is 6 business days average, measured from receipt of the required accession allocation. Rush targets are 48-hour for 4X and 4-6 business days for 8X. Paid intake is open, but unresolved method, criterion, or material evidence can hold final conformance and COA release. USP <71> is separate and requires not less than 14 days of incubation after test initiation, followed by review and any required investigation.
Is turnaround measured from when I place the order?
No, it is measured from when the vial arrives at the lab. Inbound shipping is under your control and outside ours, so counting it would let a slow courier turn into a broken promise from us. It also means the clock you are quoted is the clock we can actually keep.
Why can an 8X result take longer even though the published average is the same?
The six-business-day figure is an average, not a guarantee for every sample. 8X adds endotoxin, an elemental sweep, and a post-reconstitution stability hold of at least 24 hours. Those workflows normally run in parallel, but an investigation, repeat, or failed control can extend final review. A stability hold cannot be hurried without ceasing to be a stability result.
Do you offer a compendial USP 71 sterility test?
Yes, as controlled pre-release work. Axiom accepts a declared USP <71> service and freezes its conservative accession allocation. A compendial sterility determination and COA release remain held until QA binds the exact service scope, signed laboratory procedure, product/matrix suitability, media controls, 14-day incubation evidence, criteria, and analytical material profile. Rapid DNA may likewise be accessioned, but it remains a separately qualification-held research screen and is never USP <71>, sterility, or viable CFU.
Where do I ship my sample?
The receiving address is issued with your order, so the vial arrives keyed to the right accession rather than to a general mailbox. Start on the submit page. Ship sealed, unopened vials only.
