Your doctor will need to perform a blood test to determine if you have a low white blood cell count. Other side effects can help you determine if this test is necessary, and how severe your condition might be. Mild leukopenia is often temporary and will cease as your other symptoms lessen. If your symptoms are severe then you may need to seek treatment for your leukopenia to prevent a potential life threatening condition from developing.
