ALCOA+

The data integrity principles that GMP records must meet: Attributable (who did it and when), Legible (readable for its whole life), Contemporaneous (recorded at the time), Original (the first record or a certified copy) and Accurate (correct and checked). The plus adds Complete, Consistent, Enduring and Available. In a micro lab, ALCOA+ applies to worksheets, plate counts, incubator records and instrument data, and auditors use it to judge whether results can be trusted.
