Highlights from this day
- tb500_tobias — the honest limits: hobby chain of custody is weak and any result here should be read with that in mind 11:15
- identity_shift — i had a result i am fairly sure was a handling error on my side and i logged it as such, still working it out 13:07
- identity_shift — sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm, from memory 13:10
- invoice_mismatch — while im here post the lot, the purchase month, the lab, the number, and what you were expecting. that makes it useful later, i have it written down somewhere 14:26

a single sample tells you about a single vial. that is genuinely all it tells you

is anyone tracking results over time in a way they would share
certificate said 98.6 and the independent came back 96.8, is that a problem
thats not great

the widest spread in my data is about 2.6 percentage points across five lots from one supplier
