Setup & Configuration
New EUCAST Version?
One Click.

When EUCAST publishes updated QC tables, ASTRA lets you switch versions instantly. Ranges, targets, and available antibiotics update across your entire configuration — with zero manual data entry.

  • Switch between EUCAST QC table versions in a single click
  • Updated ranges apply to current and future data only — historical records are preserved exactly as entered
  • Add a new organism by selecting from the EUCAST QC table — all applicable antibiotics, disc contents, and reference ranges are pulled in automatically
  • Choose exactly which antibiotics your lab tests — no unnecessary clutter
  • Need a non-standard organism? Add custom strains with manually defined ranges

How It Works
From Setup to QC in Minutes

ASTRA is designed for fast deployment. Configure your organisms, start entering data, and let the system handle the analysis.

1

Configure

Set your EUCAST QC table version, select your organisms, and tick the antibiotics you test. Ranges are pulled in automatically — no manual setup.

2

Record

Enter weekly zone diameters and MIC values. Lot numbers, expiry dates, and reader details are captured alongside.

3

Analyse

Westgard rules run automatically. Levey-Jennings charts reveal trends. Violations surface in the alerts dashboard.

4

Act

Raise corrective actions from any violation. Email notifications keep the team informed. The audit log records everything.

Compliance & Audit
Audit-Ready by Design

Built for regulated environments. Every interaction is logged, every data point is traceable, and historical records are preserved indefinitely.

Corrective Actions

When a result falls outside the acceptable range, ASTRA prompts for a corrective action before the data can be saved. Every out-of-range result is recorded alongside the action taken, who recorded it, and when — giving you a complete history ready for any assessor.

  • Out-of-range results trigger a mandatory corrective action prompt
  • All corrective actions stored with organism, antibiotic, zone value, and date
  • Email notification sent to configured recipients on save
  • Dedicated Corrective Actions page with full searchable history

Audit Log

Every action in ASTRA is recorded automatically. The audit log captures logins, data saves, corrective actions, settings changes, and EUCAST version updates — each with a timestamp, user, and full context.

  • Timestamped, user-attributed entries for every action
  • Filter by category — authentication, data, settings, EUCAST
  • Deactivated organisms and antibiotics preserved, never deleted
  • Historical reference ranges retained when versions change
