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.
An observation is what you see. An inference is the conclusion you  draw from what you saw.   A common analogy;   You may be doing a chemistry experiment and when youâ¦ put two  substances together, the mixture bubbles and brown gas comes off.  You know that brown gas indicates nitrogen dioxide gas. The observation would be Mixture bubbles and brown gas is given off. The inference would be A gas is produced, nitrogen dioxide. Observations are things you use your five senses to determine - how something smells, looks, tastes, sounds, or feels.
