Built for diagnostic labs & pathology centres

Lab inventory that understands reagents, not just medicines

Post-opening expiry management, lot-level reagent tracking, QC consumption separate from patient tests, and automated cost-per-test calculation — purpose-built for the lab environment, not retrofitted from a general inventory system.

Three lab inventory problems general systems can't solve

A general pharmacy inventory system was not designed for a diagnostic lab. The problems that matter most in a lab — post-opening expiry, lot-level QC tracking, cost-per-test — are invisible to a general system.

Reagents used beyond post-opening stability — result accuracy at risk

A Troponin kit with a December 2025 printed expiry is unusable after 7 days of opening. A system that only tracks manufacturer expiry allows lab technicians to use expired-post-opening reagents without realising — until a quality audit or patient complaint surfaces the issue.

True cost-per-test unknown — QC overhead hidden in total reagent cost

Without separating QC runs from patient test runs, the reagent cost attributed to a patient test includes the QC overhead — distorting cost-per-test figures and making it impossible to accurately price tests or negotiate reagent contracts.

NABL documentation compiled manually — accreditation preparation takes weeks

Without a system logging lot-level reagent consumption, QC records, and expiry events, accreditation documentation is compiled retrospectively from bench registers — a time-consuming exercise that often reveals gaps only discovered during the NABL assessment itself.

Cost-per-test reporting

The true cost of every investigation — including QC and calibration runs, not just patient tests

HISx calculates cost-per-investigation by tracking all reagent consumption per test run — patient tests, QC runs, and calibration events — and allocating costs accurately between patient revenue and QC overhead.

  • Patient test reagent cost calculated separately from QC and calibration overhead
  • Lot-to-lot comparison — identify reagent lots with higher-than-normal consumption per test
  • Analyser utilisation efficiency — reagent cost per test by analyser, identify under-utilised instruments
  • Budget vs actual reagent spend — monthly variance reports for lab director and finance

Purpose-built for diagnostic lab operations

Post-opening expiry management

Opened-on date tracked separately from manufacturer expiry. Post-opening stability window configured per reagent type. Alerts triggered before post-opening expiry — not discovered after use.

Lot-level reagent tracking

Every reagent, calibrator, and QC material tracked at lot level from receipt through consumption and disposal. Lot numbers linked to QC performance records for deviation investigation.

Reagent reorder automation

Minimum and reorder levels set per reagent with supplier lead time factored in. Automated purchase request at reorder level — no manual stock monitoring for busy lab technicians.

NABL audit-ready logs

Lot-level receipt, consumption, QC run, calibration event, and disposal records — all timestamped and user-attributed. NABL, CAP, and NABH documentation generated on demand without manual compilation.

Reagent procurement management

Vendor rate contracts for reagent suppliers. Multi-vendor price comparison before PO. GRN with lot number and manufacturer expiry captured at receipt. Partial delivery handling for reagent kits.

BI & analytics integration

Cost-per-test, reagent utilisation, and QC consumption data available for BI dashboards via API. Cross-period trend analysis and reagent spend forecasting for budget planning.

Common questions

Frequently asked questions

Diagnostic lab inventory has unique characteristics that general hospital inventory systems handle poorly. Reagents have two distinct expiry windows — the manufacturer's printed expiry date and a much shorter post-opening stability window. QC materials consume reagent without generating patient revenue and must be tracked separately. Lot numbers affect test performance and must be tracked individually. HISx lab inventory is purpose-built for these workflows.
When a reagent kit is opened and registered in HISx, the system starts a separate post-opening stability countdown alongside the manufacturer expiry date. HISx alerts lab staff when the post-opening window is approaching — typically 7 to 30 days depending on the reagent — regardless of what the printed expiry date shows. This prevents reagents from being used beyond their stability window, protecting test result accuracy and NABL compliance.
HISx calculates cost-per-investigation by tracking reagent consumption per test run — including QC runs and calibration events that consume reagent without generating patient revenue — and dividing total reagent cost by the number of patient tests completed. This gives lab managers the true cost of running each investigation, separate from QC overhead.
Yes. HISx tracks QC materials and calibrators as separate inventory categories. QC consumption is recorded per QC run and linked to the analyser and test panel, while calibrator consumption is recorded per calibration event. This separation allows the lab to calculate true patient-test reagent costs independently of QC overheads.
HISx maintains lot-level reagent tracking with opening, consumption, and closing records for every reagent kit, calibrator, and QC material. Post-opening expiry events, QC run records, and disposal events are all logged with timestamps and user attribution. This documentation is available on demand for NABL assessors, CAP inspectors, and NABH auditors without requiring manual compilation.
