Test BackgroundAutoimmune neutropenia (AIN) is a rare condition caused by granulocyte autoantibodies. AIN in children between the ages of 6 months and 5 years is known as autoimmune neutropenia of infancy (ANI). In adult patients, AIN presents can be primary or secondary to other disorders, such as RA, SLE or CLL.
