97.4 against a certificate of 99.2 is fine. the same supplier landing low four times in a row is a question
#test-results 2025-03-30
- vat_on_import — anyone had a result they think was a lab error rather than a bad vial 13:44
- thirty_one_g — update from 3 months ago: retested the same supplier, result came back better, logged both, still working it out 13:45
- apob_over_ldl — i have never regretted spending the money on a test. i have regretted not testing twice 15:03
nice result

my result contradicts the supplier certificate, do i tell them
if the vial has been through a bad transit you are testing the transit as much as the supplier, thats just me
how much does sample handling on my end affect the number
is it worth testing if the vial has already been through a warm transit
unrelated but the widest spread in my data is about 2.6 percentage points across five lots from one supplier
i had a result i am fairly sure was a handling error on my side and i logged it as such
whats the lot
*PeptideMeter not the other one
thats a fill problem
the results in this channel skew because people test when they are suspicious. that is selection bias and it is real
selection bias
how do you post a result so it is actually useful to somebody in a year
i have never regretted spending the money on a test. i have regretted not testing twice
sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm
log the boring ones
a supplier disputing a result is rare here and it has never gone well for the supplier
my sheet has 2 lots from ERP with a spread under a point, which is tight
the widest spread in my data is about 2.6 percentage points across five lots from one supplier
