Challenge
Results arrive as unstructured text instead of discrete values
Agnotic approach
We parse OBX segments into discrete observations with LOINC codes, units, and reference ranges so results are usable for decisions and analytics.
Lab Interfaces · HL7 v2
Lab Integration Services (Quest, LabCorp, LIS)
Lab integration is HL7 v2 at its core — ORU results and ORM/OML orders across Quest, LabCorp, and hospital LIS. We build real bidirectional lab interfaces with LOINC-mapped results, not just a one-off results feed.

Trusted by global innovators
What lab integration involves
Lab integration connects a clinical platform to reference labs such as Quest Diagnostics and LabCorp and to hospital Laboratory Information Systems (LIS) so orders flow out and results flow back. At its core it is HL7 v2: ORU^R01 messages carry results, ORM^O01 (and the newer OML^O21) carry orders, and ACK messages confirm receipt. Results have to be mapped to LOINC, tied to the correct patient and order, and rendered with reference ranges, abnormal flags, and units intact.
The non-trivial part is that no two lab interfaces are identical. Quest and LabCorp each publish their own interface specifications and test procedures, every LIS has its own compendium and result formatting, and Ask-at-Order-Entry (AOE) questions, reflex testing, and corrected results all need explicit handling. We scope the labs, message types, and compendium mapping up front so results land structured and complete rather than as unparseable text blobs.
Architecture
See how we design bidirectional lab interfaces — orders out, LOINC-mapped results back, with corrected-result and reflex handling built in.
Common failure modes
Lab integration pitfalls — and how we handle them
Challenge
Every lab and LIS has a different interface spec
Agnotic approach
Per-lab discovery of message specs, compendium, and certification test procedures before we build, so surprises surface early.
Challenge
Corrected results duplicate instead of updating
Agnotic approach
Explicit corrected- and amended-result handling that updates the existing result and preserves an audit trail rather than creating a second entry.
Challenge
Results don't match cleanly to patient and order
Agnotic approach
Deterministic result-to-order matching with explicit fallback rules and a reconciliation queue for ambiguous records.
Lab APIs & Standards We Work With
The exact HL7 v2 message types, lab interfaces, and coding systems that carry orders and results.
HL7 v2 ORU results
ORU^R01 result messages parsed into structured observations with values, units, reference ranges, and abnormal flags tied to the correct order.
HL7 v2 ORM / OML orders
ORM^O01 and the newer OML^O21 order messages for outbound test ordering, including Ask-at-Order-Entry (AOE) questions.
Quest & LabCorp interfaces
Reference-lab connectivity built to Quest Diagnostics and LabCorp interface specifications and their test and certification procedures.
LIS connectivity
Hospital Laboratory Information System interfaces — compendium ingestion, result formatting, and site-specific configuration.
LOINC & terminology mapping
LOINC mapping for results and SNOMED and CPT where needed, so lab data is comparable and analytics-ready across sources.
Reflex & corrected results
Explicit handling for reflex testing, corrected and amended results, and preliminary-to-final transitions so the record stays accurate.
Where it runs
Lab integration use cases
Provider platforms
In-workflow lab ordering and structured result review inside the chart.
Diagnostics products
Biomarker and at-home testing platforms with LOINC-mapped results.
Telehealth
Virtual-visit lab ordering with results returned to the visit record.
RPM & chronic care
Recurring lab data feeding chronic-disease and monitoring programs.
Research & analytics
Structured, LOINC-coded lab data for population and research analytics.
Health systems
Hospital LIS interfaces for orders, results, and longitudinal lab data.
Lab integration that lands structured results
A result you can't parse is a result you can't act on. We build interfaces that deliver discrete, LOINC-coded observations, not text blobs.

Our Process
How a lab integration ships
We treat interface access, compendium mapping, and go-live as parallel tracks so lab orders and results flow reliably.
1.
Discovery & Scope
We map the labs, message types, and compendium in play — ORU, ORM/OML, AOE, reflex — before any code is written.
Compendium-aware design
2.
Interface Registration
We initiate Quest, LabCorp, or LIS interface onboarding, secure the connection, and confirm message specs and test procedures.
Lab onboarding
3.
Build & Test
We build the HL7 v2 parsers and order generation with LOINC mapping, validating against lab-supplied test messages and certification scripts.
Message-validated
4.
Go-Live & Monitoring
Phased cutover with interface dashboards, ACK tracking, and alerting for missed results or corrected-result mismatches.
Acknowledged & observable
Message table
Lab integration surface — message & timeline
How we approach the main data flows — the HL7 message type, typical timeline, and the friction to expect.
| Data flow | HL7 v2 message | Typical timeline | Notes |
|---|---|---|---|
| Inbound results | ORU^R01 | 3–6 weeks | OBX parsing, units, ranges, and abnormal flags must survive intact. |
| Outbound orders | ORM^O01 / OML^O21 | 4–6 weeks | AOE questions and order compendium mapping add work. |
| Quest / LabCorp | Vendor interface spec | 4–8 weeks | Each lab has its own spec and certification test procedures. |
| Hospital LIS | ORU / ORM per LIS | 4–8 weeks | Compendium and result formatting vary by site and LIS vendor. |
| Corrected results | ORU with correction flag | 2–3 weeks | Must update, not duplicate, the prior result in the record. |
Timelines assume interface access and lab test procedures are available. Compendium mapping and certification drive the schedule more than parsing.

Frequently Asked Questions
A focused lab interface — inbound ORU results with LOINC mapping — typically runs four to eight weeks. Outbound ORM/OML ordering with AOE questions, reference-lab certification, and LIS compendium mapping extend the timeline. Interface access and certification test procedures drive the schedule more than the parsing itself.
