THE DISPARITIES BETWEEN C-REACTIVE PROTEIN AND ERYTHROCYTE SEDIMENTATION RATE AS MARKERS OF INFLAMMATION

ABSTRACT

Objective: We conducted this research to try to further understand the correlation between C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Materials and Methods: This study was a retrospective study of 88 positive CRP results compared with ESR results of the patients who reviewed Alhomsi Clinical Laboratories between January 2018 to March 2019. Results: ESR was normal in 33 cases 37.5% of cases with an elevated CRP level, while ESR was elevated to different levels in 62.5% of all patients with an elevated CRP level. Conclusion: The discrepancies may be due to timing, with the rise in CRP manifesting itself before the ESR elevates, or simply because the sedimentation rate does not change with minor inflammation. Large-scale studies with a more diverse samples with different diseases and cases should be performed to understand the different comorbidities that could change the laboratory findings.
