Bidirectional communication between the chemistry analyzer and the laboratory information system has had the greatest impact on which phase of clinical testing?

• A. Preanalytical
• B. Analytical
• C. Postanalytical
• D. All of the above

Answer: (C)

The main idea is that exchanging data both ways between the chemistry analyzer and the laboratory information system most transforms the final step of testing. When results can flow automatically into the LIS and back for validation and updates, the postanalytical phase becomes faster, more accurate, and more reliable. Automatic result transfer reduces transcription errors and ensures the right patient and test data accompany each result. The LIS can auto-verify results against rules, flag abnormal or critical values, and route reports to the appropriate clinician or electronic medical record, enabling timely clinical decisions. While bidirectional communication also supports preanalytical and analytical workflows (order updates, QC review, etc.), the most impactful change is in reporting and interpretation—the postanalytical phase.
