C-reactive protein is a marker for the diagnosis of adnexitis.

Abstract The study reports the C-reactive protein (CRP) plasma concentrations in 115 women with a presumed diagnosis of acute adnexitis. In addition to CRP, blood sedimentation rate, white blood cell count and the body temperature were evaluated and compared with the clinical findings. Diagnosis was confirmed or excluded by laparoscopy (n = 69) or laparotomy (n = 9). Clinical examinations and conventional laboratory examinations were of limited value in the diagnosis of acute adnexitis. In contrast, CRP was a highly sensitive indicator of inflammatory pelvic disease. Furthermore, the CRP determination was superior in assessing the efficacy of an antibiotic treatment.
