[Lab] WWB tirz — Medutest came back 99.4% against a claimed 98.5%
WWB tirz — Medutest came back 99.4% against a claimed 98.5%. One vial, one service, one member paying, which is the only kind of result this board should treat as evidence. 99.4% and 98.5%. Those are measured, not estimated, and not rounded up in my favour. Independent testing is worth more than a supplied…
The wider-market rows in the directory carry a band and a report count and nothing else, deliberately. Anything more would be manufacturing precision that the evidence does not support.
The order I actually check things in, for anyone building a process rather than asking about one supplier.
First, the record: source page, verification log, and how many separate lots have been tested rather than how many tests exist. Second, the paperwork: ask for a batch-specific certificate and see what comes back and how fast. Third, the logistics: quoted lead time, minimum quantity, which lines are held in regional stock. Fourth, buy small and test it yourself.
Nothing in that list is exotic and all of it is answerable before you spend real money. Most of the disappointment posts on this board skipped step two.
a claim with no batch number is a marketing document
reship policy in writing before the order, not after
Correction: that supplier is in the documented twenty with a source page, not in the wider-market table. Different evidence bases entirely.
Small fix — the figure you quoted is the claimed purity from the certificate, and the independent result was the higher of the two.
buy small first, test it, then decide
buy small first, test it, then decide
Would qualify this slightly. Fewer entries means less sampling, and less sampling is not the same as a worse process.

Agreed — and the corollary is that "no data" and "bad data" have to be written differently. The table separates them for exactly that reason.

This is the whole method in one sentence. Everything else in the thread is elaboration.
Right — QSC publishes the method line on the certificate, and once you have seen one that does you notice every one that does not.

Adding the practical version: ask for lead time, minimum quantity and the batch record in the same message. Three answers, one email.

janoshik_junkie is describing the batch record test and it is the fastest signal available before you spend anything.
