Consulting a Doctor: Your Blood Test Results

Consult a doctor regarding examination issues?

Doctor, I would like to ask if this is really not a concern? Although the family medicine doctor told me today that it’s okay and not to worry too much.
These two red numbers are Lymphocyte 54.7% and Neutrophil Seg.
However, the doctor said that a white blood cell count of 5.01 is normal, and when calculating their quantities, he mentioned that since the total must equal 100, mine looks fine.
Additionally, my cholesterol is 240, and low-density lipoprotein (LDL) is 160.
I’m not sure if this is hereditary, as it seems that my father’s side has a tendency for high levels.
I consider myself to have a normal body type, but I wonder if my love for seafood might also have an impact? Thank you for your response.

Hello, regarding the blood cell part, it is indeed as your physician mentioned.
If the white blood cell count is normal, the neutrophils and lymphocytes are just a matter of ratio and usually do not require concern.
As for the cholesterol levels, the elevation is likely due to a combination of your constitution and diet.
It is recommended to start with dietary changes and exercise, and then monitor the levels.
If they remain high, it may be necessary to consider cholesterol-lowering medications.
You can consult a family medicine clinic for further evaluation.
Thank you for your inquiry.

More Info

When interpreting blood test results, it is essential to understand that various factors can influence the readings, and a single abnormal result does not necessarily indicate a serious health issue. In your case, the results show elevated lymphocyte levels (54.7%) and a slightly low neutrophil percentage (26.0%). However, your total white blood cell count (WBC) is within the normal range at 5.01, which suggests that your immune system is functioning adequately overall.

Lymphocytes are a type of white blood cell that plays a crucial role in the immune response, particularly in fighting viral infections. An elevated lymphocyte count can occur due to various reasons, including infections, stress, or even chronic inflammatory conditions. On the other hand, neutrophils are typically the first responders to infections, especially bacterial ones. A lower percentage of neutrophils can sometimes be seen in viral infections or after certain medications.

Your doctor’s reassurance that the overall white blood cell count is normal is significant. The body maintains a balance between different types of white blood cells, and fluctuations in their percentages can occur without indicating a severe problem. It is also worth noting that the body can adapt to various conditions, and the immune response can vary based on recent infections or stressors.

Regarding your cholesterol levels, a total cholesterol of 240 mg/dL and low-density lipoprotein (LDL) cholesterol of 160 mg/dL are indeed higher than the recommended levels. High cholesterol can be influenced by genetic factors, dietary habits, and lifestyle choices. If your family has a history of high cholesterol, it may be a hereditary condition known as familial hypercholesterolemia. Consuming a diet high in saturated fats, trans fats, and cholesterol can also contribute to elevated cholesterol levels. Seafood, while generally healthy, can be high in cholesterol, so moderation is key.

To manage your cholesterol levels, consider adopting a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins. Reducing saturated fat intake and increasing physical activity can also help improve your lipid profile. Regular check-ups with your healthcare provider are essential to monitor your cholesterol levels and overall health.

In summary, while your lymphocyte and neutrophil percentages are slightly outside the typical range, your total white blood cell count is normal, which is reassuring. Your cholesterol levels warrant attention, especially given your family history. It is crucial to follow up with your healthcare provider for further evaluation and management of your cholesterol levels and to discuss any concerns you may have regarding your blood test results. Regular monitoring and a proactive approach to your health can help you maintain optimal well-being.
