What does 7 percent eos mean on a hematology test?

A 7 percent eosinophil (eos) count on a hematology test indicates that 7 percent of the white blood cells in the sample are eosinophils, a type of white blood cell involved in immune responses, particularly allergic reactions and combating parasitic infections. This percentage is typically evaluated in the context of a complete blood count (CBC). An elevated eosinophil count may suggest conditions such as Allergies, Asthma, or certain infections, while a low count could be less clinically significant. Always consult a healthcare professional for interpretation based on individual health circumstances.
