Your Monocyte Count

What Causes Abnormal Monocyte Count?

Abnormal monocyte count can have various causes, ranging in severity from 'minor' 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 monocyte 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 monocyte count" as a symptom.  Here are seven possibilities:
  • Measles
  • Infectious Mononucleosis
  • Tuberculosis
  • Leukemia
  • Parasite Infection
  • Mumps
  • Chronic Inflammation

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:
significant history of cysts
history of GI infection/parasite
chronic productive cough
elevated eosinophil count
high sensitivity to bright light
moderate unexplained weight loss
postauricular node problems
severe diffuse bone pain
elevated lymphocyte count
having a moderate fever
current very sore throat
occassional 'chills'
... and more than 30 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 monocyte count:
Cause Probability Status
Infectious Mononucleosis 94% Confirm
Measles 20% Unlikely
Parasite Infection 23% Unlikely
Mumps 4% Ruled out
Chronic Inflammation 3% Ruled out
Leukemia 3% Ruled out
Tuberculosis 1% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

If you indicate having had recent lab tests, The Analyst™ will ask further questions including this one:
White Blood Count - Monocyte Percentage [fraction]
Possible responses:
→ Don't know
→ Under 4% [0.04] (low)
→ 4 to 10% [0.04-0.10] (normal)
→ 11 to 15% [0.11-0.15] (elevated)
→ Over 15% [0.15] (high)
Based on your response to this question, which may indicate low monocyte count, normal monocyte count, elevated monocyte count or highly elevated monocyte count, The Analyst™ will consider possibilities such as:
