The verdict in three sentences
For a medical analysis lab, custom software linking booking, sampling, results and billing runs 55,000 to 120,000 EUR ex. VAT in 2026, delivered in 18-26 weeks. The two structuring requirements are HL7 interoperability with analysers/LIS and HDS hosting. The decisive gain: result turnaround halved and -40% calls to the front desk.
The cost of analyser and LIS interfacing
A lab's technical core is interoperability. Every analyser and every LIS (Laboratory Information System) exchange must be made reliable.
| Interface | 2026 range (EUR ex. VAT) | Standard |
|---|---|---|
| Analyser connection (per device) | 4,000 – 9,000 | ASTM / HL7 |
| Central LIS gateway | 10,000 – 24,000 | HL7 v2 / FHIR |
| Billing & insurance interface | 8,000 – 18,000 | e-billing |
| Reference-lab interface | 5,000 – 12,000 | Test outsourcing |
| Validation middleware | 6,000 – 14,000 | Quality control |
| Patient result portal | 9,000 – 20,000 | Secure access |
A lab with 5 analysers therefore counts 20,000 to 45,000 EUR ex. VAT for hardware connections alone, on top of the application core.
Secure result portal vs paper mailing
The patient portal changes the economics of the phone desk and postal mail.
| Criterion | Paper / fax mailing | Secure result portal |
|---|---|---|
| Time to availability | 24 – 72 h | Real time on validation |
| Cost per result | 0.80 – 1.50 EUR | 0.05 – 0.15 EUR |
| Front-desk calls | High | -40% |
| Access traceability | Weak | Full (logs) |
| GDPR compliance | Fragile | Encryption, consent |
| Patient satisfaction | Average | High |
The impact on result turnaround
Turnaround time is the KPI most scrutinised by prescribers.

Mini case study
Dr. Mercier, lead biologist at a lab in Nantes, processes 900 files/day. The portal diverts 74% of result look-ups, removing roughly 48 calls/day (4 min each). That frees 3.2 hours/day of front-desk time, i.e. about 700 hours/year valued at 22 EUR, or 15,400 EUR/year. Added to postal savings (0.90 EUR × 500 paper results/day avoided), the portal alone repays a meaningful share of a 90,000 EUR build within three years, before any commercial gain with prescribers.
FAQ
Is HL7 really mandatory? It is the de facto interoperability standard linking analysers, LIS and hospital systems. Without it, each exchange becomes manual and error-prone; budget 4,000 to 9,000 EUR ex. VAT per connected analyser.
Does a lab need HDS hosting? Yes, as soon as named results are stored. Budget 8,000 to 18,000 EUR/year depending on volume and required redundancy.
How long to connect all analysers? Each analyser needs dedicated testing; count 1 to 3 weeks per device, in parallel with application development, on an overall 18-26 week project.
Is the result portal compliant? Yes, with strong authentication, encryption and patient consent. Access logs provide the traceability required by GDPR and health authorities.
Can we keep our current LIS? Often yes, via an HL7/FHIR gateway. The central LIS gateway runs 10,000 to 24,000 EUR ex. VAT depending on the system's age and openness.
