As for whether to sign the date, many people have different opinions. We will answer this question for you today:

< p>Let’s first look at the requirements of the standards:

CNAS-CL01 4.13.2.3 When errors occur in the records, each error should be crossed out and not erased to avoid blurring or disappearing, and will be The correct value is filled in next to it. All changes to the record should be signed or initialed by the person making the change. Similar measures should be taken for electronically stored records to avoid loss or alteration of original data.

< p>The original record can only be modified at that time, so there is no need to write a date at all.

The laboratory must have documented regulations on how to allow modifications, whether to use a seal, signature or initials for modification, and then all employees Follow the regulations. It is not allowed to change the original record every other day or every few days.

Except for calculation errors or textual errors, which can be corrected the next day, data and results are not allowed to be modified the next day. So there is no need to write the date at all. The recorded date can be found underneath the entire record, eliminating the need to rewrite the date next to the scratch.
