Understanding blood test results can be a daunting task, especially when faced with various medical terminologies and reference ranges. Your blood test report provides a wealth of information about your health, and interpreting these results correctly is crucial for understanding your overall well-being. Let's break down the key components of your report and address your specific questions.


Key Components of Your Blood Test Report
1. White Blood Cell Count (WBC): Your WBC count is 5,200 cells/µL, which falls within the normal range of 4,000-11,000 cells/µL. This indicates that your immune system is functioning adequately, as white blood cells are essential for fighting infections.

2. Red Blood Cell Count (RBC): At 5.320 million cells/µL, your RBC count is also within the normal range for males (4.5-6.0 million cells/µL). This suggests that your body is effectively producing red blood cells, which are crucial for transporting oxygen throughout your body.

3. Hemoglobin (HgB): Your hemoglobin level is 16.0 g/dL, which is normal for males (14-18 g/dL). Hemoglobin is the protein in red blood cells that carries oxygen, and a normal level indicates good oxygen-carrying capacity.

4. Hematocrit (Hct): At 46.4%, your hematocrit level is within the normal range for males (36-54%). This percentage reflects the volume of red blood cells in your blood, indicating adequate blood volume and oxygen transport capacity.

5. Differential White Blood Cell Count:
- Neutrophils (Net-s%): 49.8% (normal range: 40-75%)
- Lymphocytes (Lym-L%): 41.0% (normal range: 18-45%)
- Monocytes (Mono%): 7.5% (normal range: 1.2-15%)
- Basophils (Baso%): 0.4% (normal range: 0-1%)
- Eosinophils (Eosin%): 1.3% (normal range: 0-6%)
Your differential count shows that all types of white blood cells are within normal ranges, which indicates a balanced immune response. The slight elevation in lymphocytes and monocytes is not concerning unless accompanied by symptoms or other abnormal findings.

6. Platelet Count (Pla[K]): Your platelet count is 260,000/µL, which is within the normal range (140,000-440,000/µL). Platelets are essential for blood clotting, and a normal count suggests that your clotting ability is intact.

7. Mean Corpuscular Hemoglobin (MCH), Mean Corpuscular Volume (MCV), and Mean Corpuscular Hemoglobin Concentration (MCHC): These values (30.1 pg, 87.2 fL, and 34.5 g/dL, respectively) are all within normal ranges, indicating that your red blood cells are of normal size and hemoglobin concentration.


Addressing Your Specific Questions
1. Variability in Reference Ranges for Monocytes: The reference ranges for monocytes can vary between laboratories due to differences in population samples, testing methods, and statistical analysis. Your monocyte percentage of 7.5% is within the normal range provided in your report (1.2-15%), indicating that your immune system is functioning properly. If another lab lists a different range (e.g., 3-8%), it may reflect a more specific population or methodology. It's important to always refer to the reference ranges provided by the lab that performed your test.

2. Assessment of Immune Function: Based on your blood test results, there is no indication of immune deficiency. Your WBC count and differential are within normal limits, suggesting that your immune system is adequately equipped to respond to infections. However, if you have concerns about your immune health, it may be beneficial to discuss any symptoms or risk factors with your healthcare provider.


Conclusion
In summary, your blood test results appear to be within normal ranges, indicating good overall health and immune function. Variations in reference ranges for specific blood components can occur between laboratories, so it's essential to interpret your results in the context of the specific lab's reference values. If you have any ongoing health concerns or symptoms, it is advisable to consult with your healthcare provider for further evaluation and personalized recommendations. Regular monitoring and maintaining a healthy lifestyle are key to sustaining your well-being.
