Irritability in Adults
How is the condition diagnosed?
The healthcare provider begins the investigation of irritability with a history and physical exam. This may be all that is needed to make the diagnosis. In other cases, the healthcare provider may order tests such as:
a complete blood count, or CBC, to detect infection or blood cancer
x-ray tests, such as a chest x-ray, to help diagnose some infections and cancers
thyroid function tests to check for abnormalities with the body's metabolism
psychological testing to check for mental or psychological impairments
