Applicability of the Ektachem 400 analyzer for assaying analytes in miscellaneous body fluids

The Ektachem analyzer, a slide-film chemistry technology, demonstrated applicability to non-serum, non-urine stimulated and actual clinical specimens having a wide range of protein concentration and pH. The simulated specimens studied had pH and protein that ranged from 2 to 9 and 0 to 88 g/L, respectively. Actual patients' specimens studied, which had protein concentrations ranging from 0.1 to 60 g/L, included peritoneal fluid, vitreous fluid, synovial fluid, pericardial fluid, and cerebrospinal fluid. The analytes studied included glucose, urea nitrogen, uric acid, creatinine, calcium, phosphorus, sodium, potassium, chloride, and carbon dioxide.
