Common tests: introduction
Today’s technologies allow testing on an impressively wide variety of samples collected from the human body. Most often, all that is required is a blood sample. Samples of urine, saliva, sputum, feces, semen, and other bodily fluids and tissues also can be tested.
Some samples can be obtained as the body naturally eliminates them. Others are quick and easy to acquire because they reside in the body’s orifices. For some, minor surgery and anesthesia give the physician access to the required sample.
