To the Editor: In discussing the challenges
of diagnosing TA, Dr Hellmann1 repeated
a conclusion of Smetana and Shmerling2 that
a normal erythrocyte sedimentation rate (ESR) reduced the negative likelihood
ratio (LR) of TA to 0.2. Recently, we have observed physicians using formulas
to age-adjust the limit of normal ESR. For both the LR and such formulas,
some words of caution are in order.
