Brain uptake was rather stable with a variability ranging from 6%to16%6%, whereas the variability of 18F-FDG concentrations in blood and the Harderian gland was in a range of 20%to40%0%.
Families paying a caregiver were only 3% with a small variability from 1% in Piemonte (North) to 5% in Abruzzo (South).
As a result, variability from day to day and lab to lab can be considerable.
Nitrate concentrations in groundwater showed a large variability from 0.1 to 190.6 mg/L (mean = 35.0 mg/L) with significantly lower values near oxbow lakes.
Results revealed that ultrafiltration (UF) offered a lower variability from sample to sample when compared to the protein precipitation (PP) method (from 2 to 12 times lower variability found in UF).
In terms of magma composition, there is a high variability, from silicic to mafic, of the erupted lavas and tephra (Ono and Watanabe 1985; Hunter 1998; Kaneko et al. 2008).
Furthermore, haplogroup J frequencies in northern Italy shows a remarkable variability: from 3.8% in Gardena[32] 14.5% in Tuscany[1] and 28.5% in Fassa[31].
There is a vast variability from case to case in light chain proteins which are highly modified.
Rather it seems more likely that there exists a significant variability from animal to animal in the extent of the localization and the degree of overlap.
