When to see a doctor

By Mayo Clinic Staff

A low white blood cell count is usually found when your doctor orders tests for a condition you're already experiencing. It's rarely an unexpected finding or simply discovered by chance.

Talk to your doctor about what your test results mean. A low white blood cell count, along with results from other tests, might already indicate the cause of your illness. Or your doctor may suggest other tests to further check your condition.

Because a chronic very low white blood cell count makes you vulnerable to infections, ask your doctor about precautions to avoid catching contagious diseases. Always wash your hands regularly and thoroughly. You might also be advised to wear a face mask and avoid anyone with a cold or other illness.
