The ADVIA CHEMISTRY XPT SYSTEM instrument is an automated analyzer for clinical chemistry or blood chemistry tests that processes tests in serum, plasma, urine or cerebrospinal fluid in random access mode and by series with a production rate of 1800 pho- totometric tests per hour and 600 tests of electrolytes (ISE) by now. Performs colorimetry, enzymatic, puntofinal, kinetic, selective ion for electrolytes. Of continuous random access. Uses urine, serum or plasma samples for in vitro diagnostic tests (IVD) of enzymes, biochemistry, cardiovascular, oncology, anemia, electrolytes, etc. It is in automated system that reports the values of the tests and communicates the results of clinical of the patient.
