Janoshik has been the fastest for us. Medutest has been the most detailed. those are not the same lab

BB

the queue is posted and updated. if your code is not on it, it did not arrive, ask me again in a month

BB

can i add a second lot to the same submission
a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement

WT

if you want to know about your vial, you have to submit your vial. that is the whole answer

BB

we publish the raw report. summaries hide the thing you needed to see

WT

i keep half the sample back so there is something to send if the first one goes missing

SH

submissions go out blinded. the lab gets a code, not a supplier name. that removes one variable, it is not distrust

blinded obviously

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

AN

send powder

including a reference standard in the batch is the single best thing we ever added to this process

sorry to jump in two labs on the same lot is a luxury but it is how we learned what inter-lab variance looks like

who is coordinating this round

OW

declare it as an analytical reference sample with a low value. that is what it is, i could be wrong

anyone want to co-fund a quantity test on a lot i already own

BB

powder if you can. reconstituted travels worse and adds a variable we cannot control

🔥1

do i send a syringe or the whole vial

EE

chain of custody in hobby testing is weak and we say so in every writeup
do not send your only vial. that has happened twice and both times it hurt

SH

a pooled result tells you about the pool. it does not tell you about your vial

BB

coming back to this is it worth including a reference standard in the batch

BB

roughly one sample in 9 rounds has gone missing in transit. budget for it emotionally
roughly one sample in 7 rounds has gone missing in transit. budget for it emotionally

SN

send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it, thats just me

i coordinate the round, collect the codes, and post every result including the dull ones

quantity is the test worth paying for. purity is usually fine and fill usually is not

update from 24 months ago: the blinding process is unchanged and it has held up fine, thats one data point
