The Diagnostic Value of Neutrophil: Lymphocyte Ratio in Adults with Suspected Acute Appendicitis

A lower neutrophil to lymphocyte ratio is closely associated with catarrhal appendicitis versus severe appendicitis

“…The value of using the NLR to help predict the prognosis of patients with cancer has been reported [28]. Recent studies have also found that the NLR is more valuable than CRP, albumin or GPS not only for diagnosing AA [29][30][31], but also for detecting gangrenous appendicitis [27]. The NLR is much better than CRP for evaluating the acute phase of infectious disease, because pooled neutrophils in bone marrow [32] are able to respond more rapidly to infectious disease than acute inflammation-related proteins such as CRP, which is produced in the liver in response to interleukin-6 [33].…”

Acute perforated appendicitis: An analysis of risk factors to guide surgical decision making

“…[17] The most commonly performed blood investigations in patients presenting with right lower quadrant pain are a complete blood count and CRP. Our data confirm the added use of neutrophil counts and CRP in predicting an appendicular perforation as a result of acute appendicitis.…”

The Blood Neutrophil to Lymphocyte Ratio Correlates with Clinical Status in Children with Cystic Fibrosis: A Retrospective Study

“…An elevated NLR has also been associated with increased mortality after both non-ST-elevation and ST-elevation myocardial infarction [9,21]. Finally, an elevated NLR has been suggested as an adjunct to clinical evaluation in the diagnosis of acute appendicitis, with a better prognostic value than C-reactive protein or white blood cell count [22]. …”
