Step-by-step explanation:
The most appropriate solution for the LIS coordinator to consider in this situation would be to invest in equipment that can read and interpret a variety of barcode formats. This would allow the hospital to process samples with different barcode labels without the need for manual re-labeling or developing a separate LIS for the outreach program. By investing in such equipment, the hospital can efficiently handle samples received from their outreach clients and ensure compatibility with their existing LIS.
