There are some newer stool tests available that test for the presence of intestinal inflammation, but like the serum (blood) tests these are not specific for Crohn's disease and can be seen with other intestinal diseases and infections.here are a number of blood tests that may be helpful in making the diagnosis of Crohn's disease. A compete blood count (CBC) may show anemia (low red blood cells), or may demonstrate an elevated white blood cell (WBC) or platelet count (PLT), the latter of which are both markers of inflammation or infection.
Naturalistic observation. Naturalistic observation is, in contrast to analog observation, a research tool in which a subject is observed in its natural habitat without any manipulation by the observer. During naturalistic observation, researchers take great care to avoid interfering with the behavior they are observing by using unobtrusive methods.
A clear advantage to naturalistic observation is that it allows researchers to see the natural behavior of the organisms they are interested in. This can provide very valuable information which may influence future experimental research and contribute to understanding of how the organism lives in the wild.
