whats the underfill rate people are actually seeing

Highlights from this day
- deadspace — the results in this channel skew because people test when they are suspicious. that is selection bias and it is real, ill dig out the number 22:01
- slow.taper — anyone had a result they think was a lab error rather than a bad vial 22:15
- lot_number_lou — what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern, your mileage will differ 22:21
- bea_reconstitutes — coming back to this the honest limits: hobby chain of custody is weak and any result here should be read with that in mind 22:54

thats a fill problem
how much does sample handling on my end affect the number
unrelated but anyone tested the same lot twice at different labs
anyone had a result they think was a lab error rather than a bad vial

a point or two between the certificate and an independent result is inside what two labs disagree by
sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm
what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern, your mileage will differ
whats the worst result anyone has logged and what happened next
weigh the vial before you reconstitute. it costs nothing and catches the common failure
sorry to jump in 97.4 against a certificate of 98.6 is fine. the same supplier landing low four times in a row is a question

one bad test does not condemn a supplier. one good test does not clear one. both halves get ignored equally
