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.
While naturalistic observation can be useful in many cases, this method also has some potential downsides that must be considered. One of the disadvantages of naturalistic observation includes the fact that it can be difficult to determine the exact cause of a behavior and the experimenter cannot control for outside variables. Some other disadvantages of naturalistic observation: 1  People may behave differently when they know they are being watched. 2  People may try to behave in a certain way in order to conform with what they think the researchers expects to see.
