White blood cells play a key role in the immune system, explains Healthgrades. They are created in bone marrow and attack harmful foreign bodies, including viruses and bacteria. Consequently, a lower WBC count leaves the organism more vulnerable to infections.

The ramifications of low WBC count depend on a particular individual’s situation, notes Healthgrades. The normal range of WBC is 4,500 to 10,000 in one microliter of blood, and a count lower than 3,500 is usually considered low. However, the exact cut-off point depends on many factors, including the laboratory and the test that is used. Age, gender and the general level of health all influence the potential seriousness of a low WBC count.

In general, an individual with a low WBC count should avoid potential sources of infection and communicable disease, advises Healthgrades. If a low WBC count is accompanied by symptoms that include fever, a sore throat, lesions on the skin and lymph node swelling, it is necessary to seek medical attention right away.
