Knowledge of these changes over time is vital to the collection of specimens at appropriate times, selection of relevant reference values, and in diagnosis, because the absence of the expected rhythm may indicate the presence of disease [ 18].
It is hoped that with the recent identification of a hybrid abingdonii tortoise, the approximate genetic constitution of the original inhabitants of Pinta may eventually be restored with the identification and relocation of appropriate specimens to this island.
Unfortunately, such studies are largely precluded by the relative rarity of appropriate specimens.
Current surveillance protocols call for the collection of appropriate specimens for virologic surveillance during all phases of measles control.
Validation studies in dysplastic hips are not feasible due to the limited availability of appropriate specimens, and limitations of experimental models.
Microbial aetiology was identified in a high proportion of patients (72%) admitted to ICU with CAP, reflecting timely collection of appropriate specimens.
Wagoner et al. (2005), tried to apply this test methodology to smaller and disk-shaped specimens of concrete (more appropriated in case of specimens obtained from drill cores) but they ran into troubles obtaining premature failures at the pulling load holes in about 50% of the tests, thus evidencing the disability of a direct application of the procedure.
Greater use of appropriate specimen collection and confirmatory laboratory testing is needed.
First, wider use of appropriate specimen collection and handling is needed, along with laboratory testing to confirm the causative pathogens, especially for cases in young children.
The problem of appropriate specimen collection and testing in episodes of pneumonia among infants and children is magnified in settings in the developing world because of the reduced capacity for clinical procedures and because of limited diagnostic facilities; paradoxically, these settings have the greatest prevalence of severe respiratory illness [ 2, 3].
