1. 1. Invasive versus Non-Invasive Clinical Measurements in
Medicine Clinical measurement has become an essential complement to
traditional physical diagnosis. An ideal clinical measurement
should be quantitative, have a high level of reliability and
accuracy, be safe, acceptable to the patient, easy to perform and
non-invasive. The latter demands that the technique should not
break the skin or the lining epithelium and should be devoid of
effects on the tissues of the body by the dissipation of energy or
the introduction of infection [1]. It is therefore logical that for
a given measurement, a non-invasive test will be preferred if it
provides the same information with the same accuracy and precision.
In the following sections, we will discuss the role of various
non-invasive or relatively non-invasive methods to assess airway
inflammation in asthma and concentrate on the only direct method of
induced sputum examination. 1. 2. Why Is Assessment of Airway
Inflammation Important in Asthma? Inflammation is a localized
protective response elicited by injury or destruc tion of tissues
which serves to destroy, dilute or wall off both the injurious
agent and the injured tissue [2]. The role of inflammation in
asthma was rec ognized long ago. In his textbook The Principles and
Practice of Medicine, in 1892, Sir William Osler described
"bronchial asthma . . . in many cases is a spe cial form of
inflammation of the smaller bronchioles . . .
