Testing queue: 9 submissions open, 34 awaiting dispatch.

Highlights from this day
- vialkeeper — submissions go out blinded. the lab gets a code, not a supplier name. that removes one variable, it is not distrust 17:48
- larch_labs — chain of custody in hobby testing is weak and we say so in every writeup 17:52
- larch_labs — we have never had a lab mix up a sample. we have had members mix up their own labelling twice 18:07
- calgary_cold — we do not help with wording beyond that and the mods are strict about it 20:00
i coordinate the round, collect the codes, and post every result including the dull ones
in for one

Medutest has been the fastest for us. Janoshik has been the most detailed. those are not the same lab
count me in
how much sample does the lab need for purity plus quantity
blinded obviously
a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement

are we blinding this one or does the lab know the source
send powder

publish the raw
update from 8 months ago: the blinding process is unchanged and it has held up fine
two labs on the same lot is a luxury but it is how we learned what inter-lab variance looks like
submissions go out blinded. the lab gets a code, not a supplier name. that removes one variable, it is not distrust

a pooled result tells you about the pool. it does not tell you about your vial
chain of custody in hobby testing is weak and we say so in every writeup

who is coordinating this round
we have never had a lab mix up a sample. we have had members mix up their own labelling twice

slightly off topic but whats the failure rate on samples actually arriving
quantity is the test worth paying for. purity is usually fine and fill usually is not
is it worth including a reference standard in the batch
unrelated but how many people do we need before the split is worth it
unrelated but turnaround has been between 20 days and twice that depending on the queue, your mileage will differ
keep half back
we publish the raw report. summaries hide the thing you needed to see
powder if you can. reconstituted travels worse and adds a variable we cannot control
update on the earlier thing i would rather fund one careful quantity test than three purity tests
send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it
roughly one sample in 7 rounds has gone missing in transit. budget for it emotionally
how are we splitting the cost this time
including a reference standard in the batch is the single best thing we ever added to this process, take that with a pinch of salt
is there a submission going out this month and can i get in on it
how do we stop the pool telling us about the pool instead of my vial
how long do you keep the retained half of the sample
the split works from about 9 people. below that everyone pays more than the test is worth
whats the split
is there a preferred lab for quantity specifically
the queue is posted and updated. if your code is not on it, it did not arrive, n of 1 obviously
anyone want to co-fund a quantity test on a lot i already own
what happens if a submission gets lost in transit

i keep half the sample back so there is something to send if the first one goes missing
the split works from about 3 people. below that everyone pays more than the test is worth
we do not help with wording beyond that and the mods are strict about it

add a standard
do i send a syringe or the whole vial
the queue is posted and updated. if your code is not on it, it did not arrive
