A high Complete Blood Count (CBC) can indicate several different issues, depending on which specific component is elevated. A CBC measures red blood cells, white blood cells, and platelets. If any of these are higher than the normal range, it could signify an underlying health concern.
Understanding Elevated CBC Components
It is important to look at which specific element of the CBC is high because each component has a different cause and clinical significance.
High Red Blood Cell Count
- A high red blood cell count, also known as erythrocytosis, can be indicated by:
- Elevated red blood cell count
- Elevated hemoglobin levels
- Elevated hematocrit levels
- Potential Causes:
- Medical Conditions: According to the reference, erythrocytosis can sometimes be a sign of serious medical conditions like blood cancer or heart disease.
- Other Factors: Dehydration, low oxygen levels due to lung problems, and smoking can also cause high red blood cell counts.
High White Blood Cell Count
- A high white blood cell count usually indicates that your body is fighting an infection or inflammation.
- Potential Causes:
- Infections: Viral, bacterial, or fungal infections are the most common reasons.
- Inflammatory Conditions: Conditions like rheumatoid arthritis can elevate white blood cell counts.
- Other Factors: Stress, certain medications, and bone marrow disorders can also be contributing factors.
High Platelet Count
- An increased number of platelets is called thrombocytosis.
- Potential Causes:
- Reactions: Sometimes it is just a reaction to infection or inflammation.
- Underlying Conditions: In other cases it may be due to underlying conditions like bone marrow problems.
What To Do if Your CBC is High
If your CBC results are high, it is important to consult a medical professional. They can properly evaluate the results alongside your medical history and other tests to determine the underlying cause and the appropriate course of action.
| Component Elevated | Possible Causes |
|---|---|
| Red Blood Cells | Blood cancer, heart disease, dehydration, low oxygen levels, smoking |
| White Blood Cells | Infection, inflammation, stress, medications, bone marrow disorders |
| Platelets | Infection, inflammation, bone marrow problems |
