Diagnostic procedures in allergy III. Office screening for immune deficiency

Using the screening tests discussed in this review, the practicing allergist can obtain an adequate assessment of the patient's immune system. Using the clinical nature of the particular patient's infectious history as a guide to the selection of the few simple assays described, the physician can identify those patients who require further evaluation of their immune system. In addition, he can assure those who have concerns about their own or their children's immune system that it is functioning normally.
