Your Red Blood Cell Count

What Causes Abnormal Red Blood Cell Count?

In order to deal properly with abnormal red blood cell count we need to understand and — if possible — remove the underlying causes and risk factors.  We need to ask: "What else is going on inside the body that might allow abnormal red blood cell count to develop?"

Diagnose your symptoms now!
  • check your overall health status
  • identify any nutritional deficiencies
  • learn what you should be doing right now

Accurate diagnosis of the factors behind abnormal red blood cell count consists of three steps:

Step 1: List the Possible Causative Factors

Identify all disease conditions, lifestyle choices and environmental risk factors that can lead to abnormal red blood cell count.  Here are six possibilities:
  • Non-Hodgkin's Lymphoma
  • Polycythemia Vera
  • Bone Marrow Suppression
  • Anemia
  • Chronic Renal Insufficiency
  • Leukemia

Step 2: Build a Symptom Checklist

Identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
low hemoglobin levels
elevated eosinophil count
slight diffuse bone pain
pale fingernails
low lymphocyte count
loss of appetite
regular unexplained nausea
microcytic red cells
frequent unexplained vomiting
mild abdominal discomfort
elevated B12 levels
Caucasian ethnicity
... 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 red blood cell count:
Cause Probability Status
Bone Marrow Suppression 95% Confirm
Leukemia 53% Possible
Chronic Renal Insufficiency 30% Unlikely
Non-Hodgkin's Lymphoma 5% Ruled out
Anemia 5% Ruled out
Polycythemia Vera 0% 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:
Red Blood Cell count (RBC). Unit: x10^6/uL or x10^12/L. NOTE: If your results show large numbers, divide by 1000 (i.e. 3900 becomes 3.9).
Possible responses:
→ Don't know
→ Under 3.2 (very low)
→ 3.2 to 4.2 (low)
→ 4.3 to 5.4 (normal)
→ Over 5.4 (high)
Based on your response to this question, which may indicate low red blood cell count, normal red blood cell count or high red blood cell count, The Analyst™ will consider possibilities such as:

Anemia also suggests the following possibilities:


The red blood cell deficiency caused by leukemia leads to anemia and the symptoms of anemia, including severe fatigue, pallor, and breathing difficulty.
