Part of the Contemporary Geriatric Medicine book series (COGM, volume 2)


In order to be effective a practitioner must be capable of not only collecting a considerable amount of clinical and laboratory data, but also utilizing the findings to arrive at a correct diagnosis. Interpretations of all findings, regardless of whether they are derived from the history, physical examination, or laboratory data, are subject to error.1–10 When treating the elderly, errors are often magnified by such factors as an inaccurate history, misleading physical findings, and poorly established “normal” laboratory values. This chapter will discuss problems often encountered when interpreting laboratory data in the elderly, with specific examples given to help illustrate some major principles that merit special consideration.
