If a lab's QAM defined "signature" on technical records, reports and chain of custodies as the hand written signature or electronic equivalent, would this meet the signature requirement for each of these documents?

As we upgrade our LIMS and QC software, we have the ability to electronically sign off on chains and lab documents but want to know if this would be acceptable. Thank you.


Electronic signatures are acceptable (see references above) provided that the signature is unique to the individual.

Some states may have regulatory requirements pertaining to the use of electronic signatures. The laboratory should ensure that state requirements are met.
