These laboratories included healthcare facility, reference, university, research, and specialty laboratories, and their volumes ranged from a lot less than one hundred to more than 2,000 cassettes on a daily basis. In addition, released protocols from several sources had been gathered and analyzed, then included into a new and now significant, element-rich library with 276 processing protocols. This library is developing month-to-month. Thank you to all of the laboratories that have provided their protocols coupled with thorough conversations regarding their processes.
