Highlights from this day
- tb500_tobias — has a supplier ever disputed a result posted here 12:39
- VialBot — New independent result logged — QYB, lot KP-0925, purity 99.2% (Medutest). 12:42
- retention_time — i test roughly every tenth vial. it is a sampling strategy, not paranoia 12:43
- tb500_tobias — my result contradicts the supplier certificate, do i tell them the results in this channel skew because people test when they are suspicious. that is selection bias… 12:45
- egfr_ed — 99 against a certificate of 99.2 is fine. the same supplier landing low four times in a row is a question 13:25
