i keep the report in the same folder

above my pay grade, test date as well

a lab reference number is worth including because it makes the result checkable by somebody else, i bought it myself, receipts kept

do the results in this channel skew because people test when suspicious

a result without a lot number and a purchase date is an anecdote with a pdf attached, that is within what i would expect

selection bias is the biggest problem in this channel and the fix is logging the results you expected, one vial, one lab, one date

small thing do results from a pooled submission count the same as an individual one, i have looked and cannot find it

the honest framing is always the same: one vial, one lab, one date, and here is the paperwork

post the report, the lot, and where you bought it. without all three it is an anecdote, not a verdict on anybody

expected this one, logging anyway the point of posting the boring results is that a log of only exciting results is not a log

i told QSC about a result they would not have liked and they did not argue. credit where it is due, ill find the number later

four lots minimum

the band matters more than the biggest single number. this room has said that for two years, within inter-lab range

partly, one vial not a supplier

which lab
