Testing is not recommended in children less than 1 year old, as reference ranges and clinical interpretation have not been well studied for this age group. Testing of parents may be performed, but is only helpful if positive. A negative test in both parents does not completely exclude hereditary spherocytosis in their children. | ||||||||
