What Causes Abnormal White Blood Cell Count?
Abnormal white blood cell count can have various causes, ranging in severity from 'needs attention' to 'critical'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose abnormal white blood cell count, we could:
- Research the topic
- Find a doctor with the time
- Use a diagnostic computer system.
The process is the same, whichever method is used.
Step 1: List all Possible Causes
We begin by identifying the disease conditions which have "abnormal white blood cell count" as a symptom. Here are eight possibilities:
- Chemotherapy Side-Effects
- Lupus (SLE)
- Drug Side-Effects
- Diverticular Disease
- Aplastic Anemia
- Hemolytic Anemia
- Chronic Infection
Step 2: Build a Symptom Checklist
We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
frequent swollen cervical nodes
multiple swollen axillary nodes
having low melatonin levels
minor inflamed cuticles
high serum iron
regularly feeling unusually cold
... and more than 60 others
Step 3: Rule Out or Confirm each Possible Cause
A differential diagnosis of your symptoms and risk factors finds the likely cause of abnormal white blood cell count:

Leukocytes (White Blood Cell count - WBC). Unit: x10^3/uL or x10^9/L. NOTE: If your results show large numbers, divide by 1000 (i.e. 3900 becomes 3.9).

→ Under 3.5

Based on your response to this question, which may indicate very low white blood cell count, low white blood cell count, normal white blood cell count or high white blood cell count, The Analyst™
will consider possibilities such as:
Lupus, SLE (Systemic Lupus Erythromatosis)
|Active lupus and an infection may share many symptoms. Further, infection can induce a lupus flare or be difficult to distinguish from a lupus flare. A low white blood cell count is suggestive of active lupus (although certain viruses can also give a low white count) while a high count suggests infection.|Chemotherapy Side-Effects
|Radiation therapy and chemotherapy destroy fast-growing cells such as white blood cells. Patients receiving a combination of radiation therapy and chemotherapy are at greater risk of a low white count.|
... and also rule out issues such as:
