a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement

Highlights from this day
- cold_pack_carla — whats the wording on the customs declaration for a sample 16:46
- split_shipment — send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it 18:22
- HPLC_Hank — two labs on the same lot is a luxury but it is how we learned what inter-lab variance looks like 19:14
- HPLC_Hank — i coordinate the round, collect the codes, and post every result including the dull ones, happy to be corrected 19:54
- cold_pack_carla — the split works from about 4 people. below that everyone pays more than the test is worth 20:13

whats the current turnaround, last one took 13 days
a pooled result tells you about the pool. it does not tell you about your vial
coordinating this round
do i send a syringe or the whole vial
[edited]what compound should we prioritise for the next round
genuine question turnaround has been between 5 days and twice that depending on the queue, from memory
if you want to know about your vial, you have to submit your vial. that is the whole answer

is it worth including a reference standard in the batch
if you want to know about your vial, you have to submit your vial. that is the whole answer
how many people do we need before the split is worth it
dont send your only vial

we have never had a lab mix up a sample. we have had members mix up their own labelling twice
do we publish the raw report or a summary
send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it

how do we stop the pool telling us about the pool instead of my vial
genuine question how are we splitting the cost this time
whats the split
update from 26 months ago: the blinding process is unchanged and it has held up fine
powder if you can. reconstituted travels worse and adds a variable we cannot control, happy to be corrected
do not send your only vial. that has happened twice and both times it hurt
two labs on the same lot is a luxury but it is how we learned what inter-lab variance looks like

we do not help with wording beyond that and the mods are strict about it
send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it
follow up chain of custody in hobby testing is weak and we say so in every writeup, not advice obviously
i coordinate the round, collect the codes, and post every result including the dull ones, happy to be corrected

for the archive Janoshik has been the fastest for us. VendorInvestigate has been the most detailed. those are not the same lab, i could be wrong
submissions go out blinded. the lab gets a code, not a supplier name. that removes one variable, it is not distrust
unrelated but we publish the raw report. summaries hide the thing you needed to see, ill dig out the number
for the archive do not send your only vial. that has happened twice and both times it hurt
including a reference standard in the batch is the single best thing we ever added to this process
sorry to jump in is there a preferred lab for quantity specifically
the split works from about 4 people. below that everyone pays more than the test is worth
