Is it required to maintain logs for waived testing?  

Logs are useful for compiling this information in one comprehensive document. Alternatively, the organization may choose to document this information in the client chart or utilize a combination of document sources to correlate the information. For example, an organization performing occult blood testing elects to document the date of testing, client result, QC result and testing personnel initials in the client chart. A separate inventory log is maintained to track the lot of reagents and test cards in use at the time of testing. Performance of initial QC for the lot, when required by the organization's policy, could also be documented on the inventory log prior to releasing the kit for general use.
