Batch test records
The full test record for a batch.
When a batch gets tested, everything lands here: who picked the sample, who tested it, what came back — including results that disagree. This never says every vial is the same, or safe to use.
Batch codes match with or without their dashes — type it the way it is printed on the vial.

“Tested” means that sample was tested.
A pass tells you what one lab found in one sample, and how that sample was handled. It says nothing about the other vials in the batch.
When results disagree, we show both.
We never average a disagreement away. Conflicting results stay on the record until more testing settles it.
