Isolated leukopenia is relatively common in practice with most common causes being viral infections and recovery or use of over the counter meds, such as NSAID's among many others from benign cyclic changes, autoimmune, liver related or blood disorders. Clinical context and trending serial values are usually used in determining appropriate work up, ideally done by a hematologist.
