i told QST about a result they would not have liked and they did not argue. credit where it is due
attach the pdf
how do you post a result so it is actually useful to somebody in a year
posting my Medutest result on lot B-0114, what do people make of it
🤝7✅1
post the lot, the purchase month, the lab, the number, and what you were expecting. that makes it useful later
whats the underfill rate people are actually seeing
*Janoshik not the other one
unrelated but does a bad result on one lot condemn the whole supplier
has a supplier ever disputed a result posted here
whats the lot
| Evidence | Counts? |
|---|---|
| Independent report, lot you bought, lot number legible | yes |
| Independent report, no lot number | no |
| Supplier certificate only | no |
| Screenshot of a report | no |
| Blinded pooled submission | yes, for the pool |
| A friend who said it was fine | no |
weigh the vial before you reconstitute. it costs nothing and catches the common failure
thats within range

certificate said 98.6 and the independent came back 99.2, is that a problem
