Several studies report a sensitivity and specificity of 48 78 % and 71 88 %, respectively, for a single determination of CRP at 4 12 h after symptom onset [ 31– 31].
Thus, for single determination, less than 0.02 mL of blood was required.
Interobserver variation was quantified using Kappa statistics or, for continuous variables, the single determination standard deviation.
The majority of published studies [ 10, 11, 21, 24] evaluated the discriminative power for infection diagnosis of a single determination of a particular marker.
The potent cytotoxicity of 9 was confirmed in IC50 assays with authentic compound (Table 2), which demonstrated a similar potency to the 2-hydroxylamine 8 (not detected as an extracellular metabolite) and a higher potency than any of the CB 1954 metabolites in all cell lines (except AA8, in which case 9 and 4 were similar, based on a single determination for 4).
It may be questioned whether it is appropriate to use a single determination for levels of vitamin D. However, it is reassuring that a recent cohort study that measured 25OHD3 at 2 times, 3 years apart, found a high correlation between levels.
While 30 ETV firings were used for a single efficiency determination, reasonable precision could be obtained with approximately 10 firings while still employing reasonable analyte masses, i.e. approximately 20 ng.
Limits of detection are close to those for sequential single element determination in Flame AAS with primary line source that is 50 1000 times higher than the limits obtainable with common ETAAS Electrothermal Atomic Absorption Spectrometryy) instrumentation.
In conclusion, BsaXI RFLP analysis is a simple and rapid approach for the single step determination of D310 polymorphism of mitochondrial DNA.
For example, a single spirometry determination of FEV1 (forced expiratory volume in one second) is recognized to have very limited diagnostic value, whereas cross-shift spirometry is "insensitive" (Balmes, 1991; Bernstein et al., 2006a; Burge, 1982; Nicholson et al., 2005).
