verification is revoked on a confirmed failure and the revocation stays in the log permanently

blinded submissions carry more weight because they remove a variable, not because we distrust the labs
thats not evidence
revoked stays in the log
a referral link is disqualifying because it makes the reporter an interested party. that is all, from memory
what counts: an independent report, on a lot you bought yourself, with the lot number, from a lab the room recognises, n of 1 obviously
not a recommendation
coming back after 11 months, has the standard changed
nothing gets deleted
thin evidence
both numbers go in
blinded is better
[edited]a good result with bad sample handling gets logged with a note about the handling. context is part of the record
pattern not one result
what happens to the log entry when a supplier improves
we refresh on new evidence, not on a clock. an old verification with no recent results says so on the entry
is the verification log the same thing as a recommendation
the point of the standard is that it applies to suppliers we like as well as ones we do not
why is a referral link disqualifying rather than just ignored
two labs a point or two apart on one lot is normal. both go in the log with both numbers, anyway
thats evidence
| Evidence | Counts? |
|---|---|
| Independent report, lot you bought, lot number legible | yes |
| Independent report, no lot number | no |
| Supplier certificate only | no |
| Screenshot of a report | no |
| Blinded pooled submission | yes, for the pool |
| A friend who said it was fine | no |
log it either way
lot number or nothing
nothing gets deleted from the log, including our own mistakes
post the photos
refresh on evidence
the mods maintain the log. the room supplies the evidence and argues about it, which is the correct division
if the evidence is thin the entry says the evidence is thin. that is more useful than a score
post the photos
sorry to jump in somebody once offered to fund the testing programme in exchange for an entry. the offer is in the log
verification is not a recommendation. it means the evidence standard has been met, nothing more
has verification ever been reinstated after a revocation
the log is readable chronologically and that is deliberate. the trajectory matters more than the current line
[edited]what actually counts as evidence for a verification
who decides, the mods or the room
two labs a point or two apart on one lot is normal. both go in the log with both numbers
if you want to help, buy a lot, test it, and post the report with the lot number. that is the whole contribution
a supplier improving shows in the log as later entries, not as earlier entries being edited, someone check my working
i have watched this standard hold for three years including when it was inconvenient for a popular supplier
a lot number mismatch between the vial and the certificate is a serious finding. post it with photos of both
a verified supplier can still ship you a bad vial. verification is about the record, not about your parcel
log it either way, not advice obviously
verification has never been for sale and never will be. offers get posted publicly with the sender redacted, not advice obviously
we have never revoked on a single result. we have revoked on a pattern
slightly off topic but update from 15 months ago: QST added evidence and the entry now reflects it
blinded is better
do blinded submissions carry more weight than open ones
i have a result but i did not buy the lot myself, does that count
does a good result from Medutest outweigh a bad one from Medutest
revoked stays in the log
Verification log updated: GL Biochem — evidence added, status unchanged.
unrelated but what does not count: the supplier certificate alone, a screenshot, a referral link, or a friend who says it was fine
if you want to help, buy a lot, test it, and post the report with the lot number. that is the whole contribution
somebody once offered to fund the testing programme in exchange for an entry. the offer is in the log
both numbers go in
how long does a verification stay current before it needs refreshing
lot number or nothing
