[Lab] my running table: 34 tests, 11 vendors, three years
my running table: 34 tests, 11 vendors, three years, and before anyone asks: same batch throughout, single submission, no cherry-picking between services. Inter-lab variance on this assay runs roughly a point either way, driven mostly by gradient and integration. Two results inside that band agree; they do not…
Chain of custody is why member-funded testing is worth more than a supplied certificate: the vial tested is the vial that arrived at a member’s door.
Small fix — same supplier, different lot. The two rows in the log are not the same batch.
a result with no batch number is about a vial nobody can identify
Cosigning on saying who paid. It is the whole basis on which this log is worth anything.
if you are going to test, test the thing you actually received
Correction: that is the claimed figure, and the measured one is the higher of the two in your own screenshot.
That service reports area percent by default. Worth stating, since the thread has been comparing it to a mass figure.
