Identifier
2.0 / 2
The test score is calculated from purity (how much of the vial content is the expected compound, with values closest to 100% best and below 98% considered unacceptable), quantity (how close the measured amount is to the label claim, more than plus or minus 20% is unacceptable), and identifier (whether the batch this vial came from can be traced to a certificate).
