Radiometer was founded in 1935 in Copenhagen, Denmark, as a manufacturer of precision measurement instruments. The company's early products included pH meters and other electrochemical measurement devices used in laboratory and industrial applications. The name "Radiometer" reflected the company's origins in precision measurement.
Radiometer's most significant contribution to medicine came in 1954, when the company introduced the world's first commercially available blood gas analyzer. The development was done in collaboration with Danish physiologist Poul Astrup, who pioneered the clinical application of blood gas measurement. Astrup's work with Radiometer established the scientific foundation for blood gas analysis as a standard of care in intensive care medicine.
The 1954 blood gas analyzer enabled physicians to measure the partial pressures of oxygen (pO2) and carbon dioxide (pCO2) in arterial blood, along with blood pH. Before this innovation, clinicians had limited ability to assess respiratory failure, metabolic acidosis, and other critical conditions affecting blood gas composition. The analyzer transformed the management of mechanically ventilated patients and critically ill patients.
Throughout the 1960s, 1970s, and 1980s, Radiometer developed successive generations of blood gas analyzers with improved accuracy, speed, and ease of use. The company expanded its product portfolio to include electrolyte analysis (sodium, potassium, chloride), co-oximetry (hemoglobin oxygen saturation), and glucose and lactate measurement. These additions created comprehensive acute care testing platforms that could measure multiple critical parameters from a single blood sample.
The ABL series of blood gas analyzers became Radiometer's flagship product line. Successive generations of ABL analyzers were introduced over several decades, with installations in hospitals in more than 100 countries. The ABL analyzers are used in emergency departments, intensive care units, operating rooms, and other acute care settings where rapid blood gas results are essential.
In 2004, Danaher Corporation acquired Radiometer for approximately $630 million. The acquisition provided Radiometer with access to Danaher's financial resources, global distribution network, and the Danaher Business System methodology. Under Danaher ownership, Radiometer continued to develop new ABL analyzer generations with improved connectivity, automation, and analytical capabilities.
In 2013, Radiometer acquired HemoCue AB, a Swedish diagnostics company, from Quest Diagnostics for an undisclosed price. HemoCue specializes in portable, handheld point-of-care analyzers for measuring hemoglobin, glucose, and urine albumin. The acquisition expanded Radiometer's point-of-care testing portfolio beyond blood gas analysis, adding capabilities for primary care, emergency medicine, and resource-limited settings.
Radiometer subsequently developed the AQT90 FLEX immunoassay analyzer, a point-of-care platform for measuring cardiac biomarkers (troponin, BNP, D-dimer), inflammatory markers, and other analytes in acute care settings. The AQT90 FLEX competes with products from Abbott (i-STAT), Siemens Healthineers, and Roche Diagnostics.
Radiometer has also invested in digital connectivity solutions, enabling its blood gas analyzers to integrate with hospital information systems and laboratory information management systems (LIMS). This connectivity allows blood gas results to be automatically transmitted to patient records, reducing transcription errors and improving workflow efficiency.

Radiometer Medical ApS has issued FDA recalls for specific blood gas analyzer models. The California Department of Public Health has documented FDA recalls for Radiometer ABL90 Flex and Flex Plus analyzers, as well as ABL800 Flex systems. These recalls were initiated to address potential device malfunctions or performance issues that could affect test accuracy. Medical device recalls are common in the diagnostics industry, with the FDA monitoring approximately 200,000 medical devices and nearly 4,000 devices requiring recalls from 2020 to 2024 across the industry.
Radiometer must comply with stringent regulatory requirements for in vitro diagnostic devices, including FDA clearance or approval in the United States and CE marking in Europe under the In Vitro Diagnostic Regulation (IVDR). These requirements create ongoing compliance obligations and quality system requirements. The European IVDR, which took full effect in 2024, imposed stricter requirements on diagnostic device manufacturers and required recertification of many devices.
Like all medical device manufacturers, Radiometer faces challenges in maintaining consistent quality across complex analytical instruments. The company must adhere to Good Manufacturing Practices (GMP) and maintain comprehensive quality management systems. Product recalls, while not unusual for medical device companies, can affect customer confidence and require corrective actions.
Radiometer operates in a competitive diagnostics market facing pressure from well-resourced competitors including Instrumentation Laboratory (Werfen), Siemens Healthineers, and Abbott Diagnostics.
