Siemens Healthineers has received 510(k) clearance from the Food and Drug Administration for its blood urea nitrogen (BUN) and total carbon dioxide (TCO2) point-of-care tests, both of which run on the epoc blood analysis system. BUN combined with creatinine and estimated glomerular filtration rate—both of which are also available on the epoc system—aids in the differential diagnosis of renal and metabolic diseases. TCO2 in turn aids clinicians in assessing acid-base and metabolic imbalances. Siemens’ epoc system aims to provide a full blood analysis menu on a single test card, and already includes pH, partial pressure of oxygen, partial pressure of carbon dioxide, sodium, potassium, ionized calcium, hematocrit, glucose, lactate, and chloride. The epoc system delivers results in less than a minute and is designed for use in any setting where routine blood analysis is required, including critical care units, the emergency department, radiology, cardiac catheterization labs, and outpatient centers.
