Demographic characteristics, neutrophil, lymphocyte, and eosinophil counts (EC) levels were recorded. ELR, neutrophil-lymphocyte ratio (NLR) calculated.\r\nResults: In patients with FMS, the blood ELR, NLR, and EC were significantly higher compared to the control group (p&lt;0.05). In the roc curve analysis, blood NLR had 62.4% sensitivity and 50% specificity; blood ELR and EC \u2265had 60.6% sensitivity but &lt; 40 % specificity in predicting fibromyalgia.\r\nConclusion: The results of this study showed that ELR and EC are promising inflammatory markers in the diagnosis of fibromyalgia and should be evaluated in a larger population along with other hemogram parameters.\r\ndoi: https:\/\/doi.org\/10.12669\/pjms.41.7.12064\r\nHow to cite this: Raikan B, Ilhan KC, Ramazan Y.
