Temperature Correction

Nomogram

Roger W. Manley states that the Westergren erythrocyte sedimentation rate test is influenced to an important degree by normal variations in room temperature.1 For better comparability of results, quality assurance or proficiency testing programs, we advise laboratories to evaluate correcting results for temperature by using Manley’s nomogram, published in the Journal of Clinical Pathology (1957), volume 10, pages 354-356. A copy of the nomogram can be downloaded below.

Please note: This nomogram is only for use with the Westergren method for determination of erythrocyte sedimentation rate. It must not be used with the Wintrobe method.

Please note: Laboratories must evaluate the use of Manley’s nomogram by themselves individually and ensure compliance with their individual national and/or local regulatory requirements.
