The core of LabValence runs the entire testing workflow on one spine — reception and chain-of-custody, worksheets and a formula engine, enforced four-eyes review, and tamper-evident 21 CFR Part 11 signed reports. One data set, one audit trail, one access model, end to end.
Every stage shares the same record, the same custody log and the same permissions — so nothing is re-keyed, exported or lost between systems.

Book work in fast and accurately, then account for every portion, move and disposal against an unbroken chain of custody.
Register one sample or a whole grid at once against an open job, drawing the permitted tests straight from the quotation.
Capture matrix, priority, temperature and condition — anything other than satisfactory forces a note and flags a client notification.
Split samples into portions, file them into physical locations, and run a controlled disposal worklist — every move logged to custody.
Print thermal barcode labels (Zebra ZPL) with a scannable QR code and no client name — preserving analyst impartiality.
Analysts enter what they measure; the system calculates, checks and flags — so results are right the first time and traceable to the run.
Structured templates with method references and a formula engine that computes the result live as trial data is entered.
Duplicate-trial entry with an automatic agreement check, and analytical batches that tie each run's blanks and QC together.
Pull results straight from analysers over ASTM/HL7 or from file imports — as draft results that still pass normal review.
Auto-created work orders bundle tests, deadlines and the least-busy qualified analyst — with subcontracting to partner labs when needed.
The integrity controls that accreditation depends on — enforced in software, not left to habit.
The analyst who produces a result can never approve it. Out-of-spec values require a written justification before they can be accepted.
A signed, locked, tamper-evident certificate — a password re-check at the moment of signing and a captured reason, backed by a hash-chained audit trail.
Every issued report carries a QR code anyone can scan — no login — to confirm it is valid, amended or revoked.
An issued report is locked; changes go through a reasoned amendment that supersedes the original and re-runs approval and signing.
Faster turnaround once intake, testing and review share one system.
Lower cost per sample — no re-keying, no rework, no idle handoffs.
Sample throughput per analyst, without adding headcount.
Transcription errors between instrument, worksheet and report.
Figures are illustrative of gains labs typically target when a fragmented, spreadsheet-and-paper workflow is unified on a single LIMS; actual results vary by lab, scope and starting point.
Yes. The core workflow enforces the controls accreditation depends on — four-eyes review (§7.8), controlled documents, equipment calibration, method traceability and a tamper-evident audit trail — and a live ISO 17025 cockpit maps each clause to the module that satisfies it.
Issued certificates are electronically signed to 21 CFR Part 11 principles — a password re-check at signing, a captured reason, and a SHA-256 hash-chained audit trail. Once issued, the PDF is locked; any change goes through a reasoned amendment that supersedes the original.
Yes — over the ASTM and HL7 protocols for live capture, or by importing analyser output from CSV/Excel files. Imported values arrive as draft results and still pass normal four-eyes verification, so an instrument link never bypasses review.
The LIMS is the core, but the same platform carries quotations and invoicing, the full ISO 17025 quality system, procurement and inventory, CRM, and HR — all on one audit trail. Modules switch on as you grow. See all modules ›
The core workflow starts on the entry plan and deepens as you move up — one flat price per user, unlimited samples on every plan.
