- two_lifts_a_week — how much does sample handling on my end affect the number 19:24
- two_lifts_a_week — update from 12 months ago: retested the same supplier, result came back better, logged both what interests me is when the gap goes the same direction every time. once… 19:25
- fake_tracking — right so weigh the vial before you reconstitute. it costs nothing and catches the common failure 19:27
- turnaround_tam — while im here a result without a lot number and a purchase date is an anecdote with a pdf attached 20:56
- turnaround_tam — is anyone tracking results over time in a way they would share 20:58
how much does sample handling on my end affect the number

what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern

nice result
97.4 against a certificate of 96.8 is fine. the same supplier landing low four times in a row is a question, happy to be corrected
selection bias
right so how do you post a result so it is actually useful to somebody in a year
a supplier disputing a result is rare here and it has never gone well for the supplier
whats the lot
genuine question if you are testing to settle an argument you will not settle it with n of 1
how do you separate batch variance from supplier variance
weigh it first
has a supplier ever disputed a result posted here
while im here i have never regretted spending the money on a test. i have regretted not testing twice
while im here a result without a lot number and a purchase date is an anecdote with a pdf attached

*PeptideMeter not the other one
do the results in this channel skew because people test when suspicious
i told SWB about a result they would not have liked and they did not argue. credit where it is due
thats within range
[edited]one data point
attach the pdf
how many lots do you need before you can say anything about a supplier
