Age- and sex-specific pediatric reference intervals for biochemistry analytes as measured with the Ektachem-700 analyzer.

Using the Ektachem-700 multilayer film analyzer, we defined age- and sex-specific reference intervals for 20 analytes in sera from a healthy population of neonates and children ages one to 19 years. Upper and lower normal reference intervals for each analyte were determined by nonparametric methods as the 0.975 and 0.025 fractiles, respectively. Newborns have lower concentrations of total prote...

Intra-erythrocytic Mg assay in the Kodak Ektachem 700 analyzer.

2154 CLINICAL CHEMISTRY, Vol. 34, No. 10, 1988 Curves for successive dilutions of a purified serum extract paralleled standard curves (data not shown). No 1,25(OH)2D was detected in a charcoal-stripped serum sample. Mean concentrations in serum from 21 healthy men and premenopausal women were 54 (SD 19) ng/L (RIA 1) and 53 (SD 18) ng/L (RIA 2), respectively. Decreased 1,25(OH)2D was observed in...

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...

Factors influencing normal reference intervals for creatinine, urea, and electrolytes in plasma, as measured with a Beckman Astra 8 Analyzer.

In a study of 514 healthy adults, we used a Beckman Astra 8 Analyzer to establish normal reference intervals for plasma creatinine, urea, and electrolytes. For potassium and chloride these were considerably lower and higher, respectively, than previously reported ranges. All of these analytes showed significant sex-related differences; all except chloride showed age-related changes. The relatio...

Sex-specific reference intervals of hematologic and biochemical analytes in Sprague-Dawley rats using the nonparametric rank percentile method

BACKGROUND Hematologic and biochemical analytes of Sprague-Dawley rats are commonly used to determine effects that were induced by treatment and to evaluate organ dysfunction in toxicological safety assessments, but reference intervals have not been well established for these analytes. Reference intervals as presently defined for these analytes in Sprague-Dawley rats have not used international...
