RT Journal Article SR Electronic T1 Temporal Arteritis With Normal Erythrocyte Sedimentation Rate JF The Journal of the American Board of Family Practice JO J Am Board Fam Med FD American Board of Family Medicine SP 119 OP 122 DO 10.3122/jabfm.4.2.119 VO 4 IS 2 A1 Ganiats, Theodore G. YR 1991 UL http://www.jabfm.org/content/4/2/119.abstract AB The erythrocyte sedimentation rate (ESR) is used to differentiate temporal arteritis from other forms of headache in the elderly. Though temporal arteritis can occur with a normal ESR, this is not generally appreciated in primary care. The case reported here is a 74-year-old woman with biopsy-proven temporal arteritis; her ESR was 22 mm/hr. Of note, her hematocrit was more than 40 percent, a condition previously reported to be associated with temporal arteritis and a normal ESR. This discussion focuses on the diagnosis of temporal arteritis and its associated symptoms.
