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. Radiometer ABL800 Flex / ABL90 FLEX PLUS Interfacing Overview & Diagnostic Workflow
The Radiometer ABL800 Flex / ABL90 FLEX PLUS is a precision diagnostic analyzer designed for clinical laboratory testing. Connecting the Radiometer ABL800 Flex / ABL90 FLEX PLUS directly to AILS Cloud LIMS eliminates manual data entry, prevents typographical identification errors, and delivers verified results directly to ordering physicians and hospital EMRs.
AILS Gateway manages bi-directional ASTM E1394 / HL7 worklist handshakes with the Radiometer ABL800 Flex / ABL90 FLEX PLUS, streaming patient test requests as samples are loaded.
Results are checked against age- and gender-adjusted reference ranges, delta check baselines, and quality control (QC) Levey-Jennings rules before digital sign-off.

5. Radiometer Biomedical Engineering Field Notes & 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 LIS 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.
