fAIkserum

Synthetic laboratory data platform

Realistic synthetic patients and lab results — no real patient data required

fAIkserum builds entire synthetic patient populations — demographics, comorbidities and longitudinal creatinine results anchored to real reference data — then exports them as annotated CSV or HL7 so you can safely test laboratory systems and result-interpretation algorithms.

What it does

A research-grade synthetic data engine wrapped in a simple web app.

Realistic patient populations

Every patient gets a plausible life history — bimodal age distribution, sex, pregnancies and hospital admissions — generated from configurable population statistics.

Epidemiology you control

Comorbidity risk models for HIV, acute kidney injury → chronic kidney disease and type 2 diabetes, with population parameters you can tune before each run.

Labs from real reference data

Age- and sex-aware creatinine trajectories anchored to 800+ real CALIPER reference-range datasets, perturbed with realistic biological variation.

Rich, dated annotations

Each patient is labelled on every birthday and around each admission, capturing the modeled lab value and the conditions active on that exact date.

HL7 export for LIS testing

One-click HL7 v2.5.1 ORU^R01 output so you can drive a real Laboratory Information System with lifelike results — without touching real patient data.

Reproducible runs

Saved runs store their parameters and random seed, so any run can be repeated later and reproduces byte-identical output.

How to use it

From sign-in to a downloadable dataset in five steps.

Sign in

Choose how many patients

Set the number of patients to generate. Optionally open "Epidemiology parameters" to adjust demographics, admission rates, pregnancy and comorbidity risks.

Generate and explore

Review the population across the Demographics, Admissions, Comorbidities and Creatinine charts, plus a preview data grid.

Download CSV or HL7

Export the CSV bundle (a patients table and a per-date annotations table) or the HL7 message file to feed into your LIS or analysis pipeline.

Reuse saved runs

Open "Saved runs" to repeat any previous run with the exact same parameters and output.
