If your lab report does not separate bands, enter 0 and check whether the reported neutrophil percentage already includes bands (many automated analyzers report total neutrophils \u2014 do not double-count).<\/li>\n<li>Read the results: ANC in cells\/\u00b5L and \u00d710\u2079\/L, the combined neutrophil percentage, the severity classification, an interpretation and clinical notes.<\/li>\n<\/ol>\n<h2>What is the absolute neutrophil count?<\/h2>\n<p>Neutrophils are the most abundant white blood cells and the first line of defense against bacterial and many fungal infections. A standard CBC reports the total WBC count and a differential giving the percentages of each cell type. However, these percentages can be misleading: a patient can have a \"normal\" neutrophil percentage but a dangerously low number of neutrophils if the total WBC count is low, or a seemingly low percentage with an adequate absolute count if the WBC is high.<\/p>\n<p>The ANC resolves this by converting the percentages into an absolute number of circulating neutrophils. It is the standard measure used to assess immune status, particularly in patients receiving chemotherapy, patients with suspected drug-induced neutropenia, and anyone presenting with fever and a low blood count.<\/p>\n<p>The most important clinical application is <strong>neutropenia grading<\/strong>. By convention in adults, an ANC of 1500 cells\/\u00b5L or more is considered normal; 1000\u20131499 is mild neutropenia; 500\u2013999 is moderate; below 500 is severe, and below 100 is sometimes described as profound neutropenia. Severe neutropenia substantially raises the risk of serious infection, and fever in a severely neutropenic patient (febrile neutropenia) is treated as a medical emergency requiring prompt empiric antibiotics.<\/p>\n<h2>Assumptions and limitations<\/h2>\n<ul>\n<li>The calculator follows the classic <strong>segs + bands<\/strong> method. Many modern automated differential counters report total neutrophils without separating bands; in that case simply enter the total neutrophil percentage and set bands to 0.<\/li>\n<li>The thresholds displayed are the common <strong>adult<\/strong> cutoffs used mainly for treatment-related (e.g. chemotherapy) neutropenia. Neonatal, pediatric and pregnancy-specific reference ranges differ, so interpret results against the appropriate range for the patient.<\/li>\n<li><strong>Benign ethnic neutropenia:<\/strong> people of African, Middle Eastern and certain other ancestries with the Duffy-null phenotype commonly have ANCs of roughly 600\u20131000 cells\/\u00b5L with no increased infection risk. A mildly low result in isolation should not be over-interpreted; a repeat CBC and the trend over time matter more than a single value.<\/li>\n<li>A manual band count is imprecise, and results vary between laboratories and methods. This tool is a calculation aid for clinicians and trained users, not medical advice \u2014 always verify values against the actual lab report and consider the full clinical picture.<\/li>\n<\/ul>\n<p>For related laboratory and clinical assessments on this site, see the <a href=\"https:\/\/wpcalc.com\/en\/medical\/anion-gap-calculator\/\">anion gap calculator<\/a> for metabolic evaluation, the <a href=\"https:\/\/wpcalc.com\/en\/medical\/sirs-criteria-calculator\/\">SIRS criteria<\/a> and <a href=\"https:\/\/wpcalc.com\/en\/medical\/qsofa-score-calculator\/\">qSOFA score<\/a> calculators for screening suspected infection or sepsis, and the <a href=\"https:\/\/wpcalc.com\/en\/medical\/sofa-score-calculator\/\">SOFA score calculator<\/a> for organ dysfunction assessment in acutely ill patients.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Calculate the absolute neutrophil count (ANC) from the WBC count and the segmented neutrophil and band percentages, with automatic severity classification of neutropenia.<\/p>\n","protected":false},"author":3168,"featured_media":0,"comment_status":"open","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[8],"tags":[50],"class_list":["post-67249","post","type-post","status-publish","format-standard","hentry","category-medical","tag-diagnostics"],"acf":[],"_links":{"self":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts\/67249","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/users\/3168"}],"replies":[{"embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/comments?post=67249"}],"version-history":[{"count":1,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts\/67249\/revisions"}],"predecessor-version":[{"id":67258,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts\/67249\/revisions\/67258"}],"wp:attachment":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/media?parent=67249"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/categories?post=67249"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/tags?post=67249"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
