The exact effects of a high white blood cell count depend on the condition or factor causing them. After noting any symptoms, a doctor can use a blood test to assess the white blood cell count, and further tests and examinations will often be necessary to pinpoint the exact cause of the problem.
A high white blood cell count may indicate several things, such as the immune system is working to destroy an infection, a sign of physical or emotional stress, or particular types of cancer. Pregnancy also leads to high white blood cell count, as levels tend to rise from the first trimester, into the third.
White blood cell levels will also rise in the hours following labor, due to the severe stress the body undergoes. Meanwhile, a low white blood cell count can signal that an injury or condition is destroying cells faster than the body is making them.
It could also mean that the body is producing too few of them. While symptoms will depend on the cause of the high white blood cell count, fluctuations in white blood cell count may not cause any symptoms. Read the article in Spanish.

These include: Neutrophils are the first responder of immune cells. Basophils release histamine to mount a non-specific immune response. Eosinophils fight bacteria and parasites but also provoke allergy symptoms. Lymphocytes are B and T cells that defend against specific invaders. Monocytes clean up dead cells.
