When to see a doctor

By Mayo Clinic Staff

A test a health care provider orders to diagnose a condition can reveal a low white blood cell count. A low white blood cell count is rarely found by chance.

Talk to your care provider about what your results mean. A low white blood cell count plus results from other tests might show the cause of your illness. Or you might need other tests for more information about your condition.

A very low white blood cell count over time means you can get infections easily. Ask your care provider about ways to not catch diseases that are passed from one person to the next. Wash your hands regularly and well. Consider wearing a face mask and stay away from anyone with a cold or other illness.
