Radiometer ABL800 Flex / ABL90 FLEX PLUS Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Radiometer ABL800 Flex / ABL90 FLEX PLUS on AILS Cloud LIMS.
1. Instrument Overview & Interfacing Architecture
The Radiometer ABL800 Flex / ABL90 FLEX PLUS is a high-performance blood gas (abg) instrument designed for diagnostic laboratories and hospital health networks. Integrating this analyzer directly with AILS Cloud LIMS eliminates manual transcription delays, prevents typographical patient identification errors, and automatically enforces Westgard delta check algorithms.
AILS automatically generates worklist queries (QRY^Q02 / ASTM orders) mapped to patient accession barcodes and pushes test instructions directly to the instrument sample tray.
Raw OBX / Result records are parsed instantly within 200 milliseconds, flagged for abnormal reference ranges, and linked to pathologist digital signature queues.

5. Biomedical Engineering Tips & Common Gotchas
In ABL800 communication settings, configure LIS Protocol to ASTM E1394 or HL7 Standard on Port 5001.
Check patient temperature correction mode (pH(T), pCO2(T), pO2(T)) if entering body temperature.
Critical blood gas panic values (e.g. pH < 7.20 or Lactate > 4.0 mmol/L) trigger immediate ICU emergency notifications.
Frequently Asked Questions: Radiometer ABL800 Flex / ABL90 FLEX PLUS Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: What protocols are supported by Radiometer ABL800 Flex and ABL90 FLEX PLUS?
Radiometer blood gas analyzers support ASTM E1381/E1394 and HL7 over TCP/IP Ethernet (Port 5001) or RS-232 serial connection.
Q: How does AILS handle calculated blood gas parameters (Base Excess, Standard Bicarbonate, Alveolar-Arterial Gradient)?
AILS automatically verifies and stores all transmitted derived parameters including Base Excess (cBase), Anion Gap, and AaDO2 alongside measured primary analytes.
Q: How does optical co-oximetry synchronization work on ABL800?
Total Hemoglobin (ctHb), Oxyhemoglobin (sO2), Carboxyhemoglobin (COHb), Methemoglobin (MetHb), and Deoxyhemoglobin (HHb) measured via 128-wavelength spectrophotometry are parsed into dedicated LOINC fields.
Q: Can Radiometer analyzers receive patient demographics via barcode scan?
Yes. When a blood gas syringe barcode is scanned, AILS Gateway sends patient ID, name, ward location, and FiO2 ventilator settings to the analyzer.
Q: What serial cable is required for ABL800 serial interfacing?
A standard DB9 Female Null Modem serial cable (Pins 2-3, 3-2, 5-5) configured at 9600 baud, 8 data bits, Parity None, 1 stop bit.
