Assessment of immunity

An approach to the assessment of the immune system primarily from the vantage point of the general physician is presented, indicating the clinical situations where analysis is most likely to yield informative results. Preliminary screening by the primary physician is discussed, followed by a brief description of measures which are employed in referral centers. A definitive diagnosis should be possible in nearly all cases. With the rapid advances in recombinant DNA technology and bone marrow transplantation, a cure can be expected for most patients, particularly if the diagnosis is made early.
