whats the worst result anyone has logged and what happened next

do you test every order or sample it

my result contradicts the supplier certificate, do i tell them

my vial assayed under label but the purity was fine, which matters more

does a bad result on one lot condemn the whole supplier

weigh the vial before you reconstitute. it costs nothing and catches the common failure

i test roughly every tenth vial. it is a sampling strategy, not paranoia, ask me again in a month

a point or two between the certificate and an independent result is inside what two labs disagree by

follow up how do you separate batch variance from supplier variance
