What a sudden change in erythrocyte sedimentation rate mean?

Osinophils are a type of white blood cell usually representing less than 8% of the total white blood cell population. The number of these cells (eosinophil count) with illnesses, such as Allergies, Asthma, Addison's disease, sarcoidosis, parasite infections, drug reactions, and connective tissue diseases (like rheumatoid arthritis and scleroderma). A high ESR means that there is some sort of inflammation in the system. The ESR is not a test designed to pinpoint the reason for the inflammation. However a high eoeinophil count could explain the high ESR.
