when is a white blood cell count too low?

Answer 1

This can vary slightly from lab to lab, but for the lab in the hospital where I work the normal limits are
N = 4-11 X10^9 white blood cells/ L

Your white cell count would be low if it was <4X10^9/L

However, the significance of this is variable. For example, it would be quite serious if you had just had chemotherapy and had a low blood count and had a fever, or if you were severely unwell with high fevers and being very sick! However, some minor viral illnesses could cause low white blood cell count, but without much significance as you would recover well anyway.

Answer 2

Also known as: WBC count, Leukocyte count, White count. A standard reference range is not available for this test. Because reference values are dependent on many factors, including patient age, gender, sample population, and test method, numeric test results have different meanings in different labs. Your lab report should include the specific reference range for your test. I strongly recommend that you discuss your test results with your doctor.
An elevated number of white blood cells is called leukocytosis. This can result from bacterial infections, inflammation, leukemia, trauma, or stress.
A decreased WBC count is called leukopenia. It can result from many different situations, such as chemotherapy, radiation therapy, or diseases of the immune system.
Eating, physical activity, and stress can cause an increased WBC count.
Pregnancy in the final month and labor may be associated with increased WBC levels.
If you have had your spleen removed, you may have a persistent mild to moderate increased WBC count. The WBC count tends to be lower in the morning and higher in the late afternoon. WBC counts are age-related. On average, normal newborns and infants have higher WBC counts than adults. It is not uncommon for the elderly to fail to develop leukocytosis as a response to infection.
There are many drugs that cause both increased and decreased WBC counts.
