When to see a doctor

By Mayo Clinic Staff

Neutropenia doesn't cause obvious symptoms. So it alone likely won't prompt you to get a healthcare checkup. Most often, blood tests that are done for other reasons find neutropenia.

Talk with your healthcare professional about what your test results mean. You'll need more than one blood test to confirm that you have neutropenia. You also may need more tests to find out what's causing your neutropenia. A finding of neutropenia combined with the results from other tests might pinpoint the cause.

If you have neutropenia or take medicines that can cause neutropenia, call your healthcare professional right away if you notice symptoms of an infection. Infection symptoms can include:

  • Fever above 100.4 degrees Fahrenheit (38 degrees Celsius).
  • Chills and sweats.
  • A new cough or a cough that becomes worse.
  • Shortness of breath.
  • A stuffy nose.
  • A sore throat or a new mouth sore.

Some other possible symptoms of an infection are:

  • Burning or pain with urination.
  • A stiff neck.
  • Diarrhea or vomiting.
  • A change in skin color or swelling around any area where skin is broken or cut.
  • Unusual vaginal discharge.
  • New pain, including in the stomach area or rectum.

If you have neutropenia, you can take steps to lower your risk of infections. These safety measures include the following:

  • Stay up to date on vaccinations, such as those for the flu and COVID-19.
  • Wash your hands often.
  • Wear a face mask in crowded places or around people who are sick.
  • Try not to have close contact with people who are sick.
  • Cook meat and eggs thoroughly to kill any germs.
  • Wash raw fruits and vegetables well.
  • Don't share food, drink cups, utensils or toothbrushes.
