ASTM analyzer interface for laboratory information systems

ASTM integration usually describes serial or TCP-based communication where the analyzer and LIS exchange structured records for orders, results, QC, and sometimes query/ack sequences. Unlike enterprise HL7 routes, ASTM conversations are often tightly coupled to a single device channel.

In bidirectional mode, the LIS pushes worklists to the analyzer and receives completed runs with flags, dilutions, and repeat patterns. Pre-analytical rules in the LIS decide what is eligible to download, while post-analytical rules determine whether results auto-verify or require technologist review.

Mapping covers not only test codes but units, reference ranges, abnormal flags, and reflex logic. Clock synchronization matters: mismatched timestamps complicate QC review and correlate with message rejection. Channel logs should correlate LIS events with raw frames for troubleshooting.

Hospital-facing HL7 feeds rarely replace ASTM for every instrument. A mature architecture uses HL7 for ADT/order/result enterprise hops and ASTM (or vendor SDKs) where the device requires it. Medrara treats both as first-class integration surfaces when enabled for your deployment.

Laboratory operations should own periodic re-validation after firmware upgrades, reagent lot changes that affect ranges, and instrument service events. IT owns network segmentation, certificate rotation where applicable, and firewall policy.
