The micro-erythrocyte sedimentation rate in black neonates and children. Part II. A comparative study of the micro-erythrocyte sedimentation rate, C-reactive protein test and total white cell count.

The value of determination of the micro-erythrocyte sedimentation rate (ESR), testing for the presence of serum C-reactive protein (CRP) and the total white cell count (WCC) has been assessed in neonates and children, both healthy and in disease states. The results show that collective and maximum use of all three investigations aids diagnosis because these tests are simple, quick, cheap and easy to perform. Furthermore, the study has demonstrated that compared with a high ESR and WCC, the presence of CRP was the best single indicator of infection. The CRP test has the greatest predictive value and sensitivity in that it indicates the intensity of an infection as well as the patient's response to therapy.
