What is eosinophilia and how it diognise?
Eosinophilia is the state of having a high concentration of eosinophils (eosinophil granulocytes) in the blood. The normal concentration is between 0 and 0.5 x 109 eosinophils per litre of blood. Eosinophilia can be reactive (in response to other stimuli such as allergy or infection) or non reactive. The symptoms of eosinophilia are those of the underlying condition. For example, eosinophilia due to asthma is marked by symptoms such as wheezing and breathlessness, whereas parasitic infections may lead to abdominal pain, diarrhoea, fever, or cough and rashes.
