We used a Veenstra VDC 404 dose calibrator as reference, and all devices in the cross-calibration should measure the same concentration within ±5%% of the reference concentration, i.e., have Xcal concentration ratios in the range [0.95 1.05].
In experimental comparisons, the number concentrations of laboratory and atmospheric aerosols measured by the UFPM were within a range of ±20% of the reference concentration determined by an SMPS.
> Thirty-nine patients [46.4%9595% CI: 35.5 57.7%)] in the PP population maintained a mean Hb concentration within ±1.0 g/dL of the reference Hb concentration and between 10.0 and 12.0 g/dL during the EEP.
Within the reference range HCV RNA concentrations detected by the AMPLICOR assay correlated with PCR.
A higher admission lactate (LacADM) concentration within the reference range was associated with higher crude hospital mortality, with a mortality rate of 18.5% in the higher risk cohort.
Thus, there are individuals with a serum magnesium concentration within the reference interval who have a total body deficit for magnesium.
Only adolescents who had taken at least three saliva samples taken on awakening between 6 am and 8 am and with a cortisol concentration within the reference range of 3.0 to 54.9 nmol/L, as suggested by Groschl, Rauh & Dorr [ 19], were included in the validation analysis.
Higher admission and time-weightedlactate concentration within the reference range was independently associated with increased hospital mortality (admission odds ratio (OR) 2.1, 95% confidence interval (CI) 1.3 to 3.5, P = 0.01; time-weighted OR 3.7, 95% CI 1.9 to 7.00, P < 0.0001).
The increase in urinary excretion of APOH and low-MW proteins in subjects with plasma creatinine concentrations within the reference range and normal urinalysis, as MOH patients enrolled in our study, may be explained by an overflow mechanism.
No compound was predicted to produce estradiol concentrations within the reference range for males or females.
