Elevated neutrophils and decreased lymphocytes?


Hello Dr.
Hsiao, my health report shows elevated segmented neutrophils and decreased lymphocytes.
The percentage of segmented neutrophils is H 75.4, while the standard range is 40.0 - 74.0.
The percentage of lymphocytes is L 18.8, with a standard range of 20.0 - 45.0.
Should I consider re-testing or take any specific actions? Thank you.

Dear Mr.
Kuo: 1.
Please pay attention to your health examination report; do you have any recommendations regarding this matter? 2.
The percentage of segmented leukocytes in the total white blood cell count is slightly elevated, which may sometimes be a transient variation and should not be a concern.
3.
If you have any questions, it is advisable to return to the original examination hospital for further clarification.

More Info


When interpreting blood test results, particularly concerning segmented neutrophils (often referred to as "neutrophils") and lymphocytes, it's essential to understand what these components indicate about your immune system and overall health. Your report shows elevated segmented neutrophils at 75.4% (normal range: 40.0 - 74.0%) and decreased lymphocytes at 18.8% (normal range: 20.0 - 45.0%).

Understanding Neutrophils and Lymphocytes
Neutrophils are a type of white blood cell that plays a crucial role in the body's defense against infections, particularly bacterial infections. An elevated neutrophil count, known as neutrophilia, can occur due to various reasons, including:
1. Infections: The most common cause of high neutrophil levels is an acute infection, particularly bacterial infections.

2. Inflammation: Conditions that cause inflammation, such as autoimmune diseases or inflammatory disorders, can lead to increased neutrophil production.

3. Stress Responses: Physical or emotional stress can also elevate neutrophil levels.

4. Medications: Certain medications, such as corticosteroids, can increase neutrophil counts.

5. Smoking: Tobacco use is associated with higher neutrophil levels.

On the other hand, lymphocytes are another type of white blood cell that is vital for the immune response, particularly in fighting viral infections and in the regulation of the immune system. A low lymphocyte count, known as lymphopenia, can be caused by:
1. Viral Infections: Some viral infections can lead to a temporary decrease in lymphocyte levels.

2. Chronic Stress: Prolonged stress can suppress lymphocyte production.

3. Autoimmune Disorders: Conditions like lupus or rheumatoid arthritis can affect lymphocyte levels.

4. Bone Marrow Disorders: Conditions affecting the bone marrow can lead to decreased lymphocyte production.

5. Nutritional Deficiencies: Deficiencies in certain vitamins and minerals, such as vitamin B12 or folate, can impact lymphocyte levels.


Clinical Significance
The combination of high neutrophils and low lymphocytes can indicate an ongoing infection or inflammatory process. It is essential to correlate these findings with any symptoms you may be experiencing. For instance, if you have signs of infection (fever, chills, fatigue, etc.), this could explain the elevated neutrophils. Conversely, if you feel well and have no symptoms, it may be a transient change that could resolve on its own.


Next Steps
Given your results, here are some recommendations:
1. Monitor Symptoms: Pay attention to any signs of infection or other health issues. If you develop symptoms such as fever, persistent fatigue, or unusual bruising, seek medical attention promptly.


2. Follow-Up Testing: It may be beneficial to repeat the blood test in a few weeks, especially if your symptoms persist or worsen. This can help determine if the changes in your blood cell counts are persistent or transient.

3. Consult Your Healthcare Provider: Discuss your results with your healthcare provider. They may recommend further testing or evaluation based on your clinical history and any symptoms you may have.

4. Lifestyle Considerations: Ensure you are maintaining a healthy lifestyle, including a balanced diet, regular exercise, and adequate sleep, which can all support immune function.

5. Avoid Self-Diagnosis: While it's natural to be concerned about abnormal lab results, avoid jumping to conclusions without a thorough evaluation by a healthcare professional.

In summary, while your blood test results show some abnormalities, they need to be interpreted in the context of your overall health and any symptoms you may be experiencing. Regular follow-ups and open communication with your healthcare provider are key to managing your health effectively.
