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
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 are lab integration services?
Lab integration services connect your clinical platform to reference labs such as Quest Diagnostics and LabCorp and to hospital laboratory information systems (LIS), so orders go out and results come back as structured data. Agnotic Technologies builds the HL7 v2 and FHIR interfaces, LOINC mapping and result routing that put each result on the right patient and order.
At its core, lab integration is HL7 v2: ORU^R01 carries results, ORM^O01 (or the newer OML^O21) carries orders, and ACK confirms receipt. Results must map to LOINC, tie to the correct patient and order, and keep reference ranges, abnormal flags and units intact.
No two lab interfaces match. Quest and LabCorp publish their own specifications and test procedures, every LIS has its own compendium, and Ask-at-Order-Entry (AOE) questions, reflex testing and corrected results need explicit handling. We scope labs, message types and compendium mapping up front.

See how we design bidirectional lab interfaces: orders out, LOINC-mapped results back, with corrected-result and reflex handling built in.
Common failure modes
Where do lab integrations fail?
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.
What do our lab integration services include?
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 integration
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

Our Process
How do we build a lab integration?
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
Local lab onboarding
How do you onboard a local or regional lab?
You onboard a local or regional lab by surveying what its system can send, setting up ordering details, mapping its test compendium and validating sample messages before a parallel run. Timing depends on the lab's interface team, so we date the plan after the survey.
Survey the lab's capabilities
Which HL7 v2 version the lab sends, whether orders go as ORM or OML, how messages travel (VPN, SFTP or an HTTPS endpoint), and whether results arrive as discrete OBX values, formatted text or PDF reports.
Set up the CLIA number and ordering providers
Record the lab's CLIA certificate number for results and reports, and register each ordering provider's NPI with the account or client number the lab expects on every order.
Import the test compendium
Load the lab's orderable tests, specimen requirements and Ask at Order Entry questions from its compendium file, and agree how the lab will send compendium changes after go-live.
Map each test to LOINC
Map results test by test to LOINC, checking units and specimen type, instead of passing the lab's local codes through. Any test without a confident match goes to your clinical lead for review.
Validate orders and results with sample messages
Send ORM or OML orders to the lab's test system and process its sample ORU results, including preliminary, corrected and reflex results, until every test in scope passes.
Run a parallel results check
For an agreed set of live orders, compare each result in your platform field by field against the lab's own report or portal before the old route is switched off.
Sign off and monitor
The lab and your clinical lead sign off the test list. From the first live day, monitoring tracks ACKs, unmatched results and compendium changes.
Message table
Which HL7 messages carry lab orders and results?
How we approach the main data flows: the HL7 message type and the friction to expect.
| Data flow | HL7 v2 message | Notes |
|---|---|---|
| Inbound results | ORU^R01 | OBX parsing, units, ranges, and abnormal flags must survive intact. |
| Outbound orders | ORM^O01 / OML^O21 | AOE questions and order compendium mapping add work. |
| Quest / LabCorp | Vendor interface spec | Each lab has its own spec and certification test procedures. |
| Hospital LIS | ORU / ORM per LIS | Compendium and result formatting vary by site and LIS vendor. |
| Corrected results | ORU with correction flag | Must update, not duplicate, the prior result in the record. |
Compendium mapping and each lab's certification testing drive the schedule more than parsing. We give you a timeline after scoping.
Facts and sources
Which rules shape lab integration?
Short facts we design around, each linked to its primary source.

Frequently Asked Questions
It depends on the lab's interface onboarding queue, whether you need results only or bidirectional ordering, how many tests need LOINC mapping and Ask at Order Entry questions, and the lab's own test and certification procedures. Interface access usually sets the pace more than parsing, so we request it at the start.
Cost grows with the number of labs and LIS you connect, whether you need inbound results only or ordering as well, the size of each compendium to map, and the reflex and corrected-result handling your clinicians need. We scope against the labs and message types you need in discovery.
Yes. We build the steps an at-home test needs: ordering the kit under a provider's authorization, registering the kit to the patient when it is activated, tracking the sample to the lab and returning the result to the patient and care team as LOINC-coded data. Each lab's kit registration and labeling rules are confirmed during scoping.
Yes. Quest Diagnostics and LabCorp each require formal interface onboarding, adherence to their published interface specifications, and completion of their test and certification procedures. We initiate that onboarding early and validate against lab-supplied test messages before go-live.
Yes. We combine lab results with remote patient monitoring and wearable data and wire lab ordering into telehealth visits, so a virtual encounter can order tests and return structured, LOINC-mapped results to the record over HIPAA-covered pipelines.
Yes. We handle corrected and amended results by updating the existing observation with a preserved audit trail rather than creating duplicates, and we support reflex testing and preliminary-to-final transitions so the lab record stays accurate.
Sometimes. If the lab cannot send HL7 v2, results can come as files over SFTP or as PDF reports with the values extracted and checked, and orders can go in a file format both sides agree. These routes need more validation, so we confirm them during the capability survey.
