Pleural Fluid pH Testing Now Available on Siemens Blood Gas System
28 Sep 2012

Siemens Healthcare Diagnostics has received CE Mark approval to offer pleural fluid pH testing on its RAPIDPoint® 500 Blood Gas System. This provides clinicians, laboratories and point-of-care coordinators with an important new diagnostic tool for use in critical care situations. Pleural fluid effusions may be a symptom of underlying illness such as heart failure, pulmonary embolism, cancer and kidney disease.

When a patient’s pleural fluid pH is less than 7.30 (normal pleural fluid pH is estimated at 7.64), it may suggest the presence of an inflammatory or infiltrative process. While these measurements can be taken using pH meters or indicator sticks, multiple studies have shown these methods to be less accurate than readings conducted using a blood gas analyzer.

The addition of pleural fluid pH testing on Siemens’ RAPIDPoint 500 system complements the analyzer’s comprehensive critical care menu, which includes tests for blood gases, electrolytes, glucose and lactate and full CO-oximetry, including total neonatal bilirubin. The RAPIDPoint 500 system uses proven Siemens technology to deliver laboratory-quality results at the Point of Care in approximately 60 seconds from a single, whole blood sample. The analyser’s measurement cartridges last up to 28 days and contain a full complement of tests, reducing downtime and increasing efficiency.
