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.
Observation: Summary. Naturalistic observation refers to collecting data without interfering with the ongoing behavior. Observation relies on information available to the senses -- sight, hearing, touch, etc. It provides information about the what of behavior, but does not reveal it underlying motivation (the why). Observational research begins with casual observation - checking out the setting and the activities that occur there. To collect valid data, it is important to distinguish between observation and inference. Systematic observation uses decision rules and operational definitions in order to reduce error.
