Blood Test Results: Key Insights for Your Health

Blood disorders

In March, I experienced recurrent episodes of urticaria every 2 to 3 days.
On April 2, I visited the rheumatology and immunology department for an examination.
The doctor ordered blood tests to check liver and kidney function.
Upon reviewing the report, I noticed some values highlighted in red.
When I asked the doctor about them, he reassured me that the values were not concerning.
I checked the health insurance app and found the following results: serum creatinine (CRE) 0.48, white blood cell count (WBC) 6220, neutrophils (NEUT) 77.8%, lymphocytes (Lym) 17.6%.
Could you please advise what these values indicate regarding my health status and how long I should wait before having another blood test? Thank you.
Since I started taking antihistamines in April, my urticaria has not recurred by the end of the month.
Is it safe to discontinue the medication? Thank you.

Hello, thank you for your inquiry.
Here is my response summarized as follows:
1.
Serum creatinine (CRE) is 0.48, white blood cell count shows NEUT 6220, N.seg 77.8, Lym 17.6.
The CRE indicates kidney function, while the other values reflect white blood cell counts.
Although these results are highlighted in red, it simply means they are slightly outside the reference range set by the testing machine, but they are still considered normal, so there is no need for concern.
I believe there is no need for further blood tests.
2.
You started taking antihistamines in April, and by the end of the month, you have not experienced any hives.
Can you stop the medication? I think you can try stopping the medication.
If the hives reoccur, it indicates that treatment may still be necessary for a while longer.
As for how much longer you should continue the medication, it varies by physician's experience, so I recommend discussing this with your doctor.

Best regards from the Allergy, Immunology, and Rheumatology Department of Changhua Hospital, Ministry of Health and Welfare.

More Info

Understanding blood test results is crucial for monitoring your health and identifying potential issues. Based on the information you provided, let's break down the key components of your blood test results and what they may indicate about your health.

Key Blood Test Indicators
1. Creatinine (CRE): Your creatinine level is 0.48 mg/dL, which is considered low. Normal ranges typically fall between 0.6 to 1.2 mg/dL for adults. Low creatinine levels can sometimes indicate decreased muscle mass or malnutrition, but in the context of your overall health, it may not be a significant concern. It’s essential to consider this value alongside other kidney function tests and your overall health status.

2. White Blood Cell Count (WBC): Your neutrophil count (NEUT) is 6220 cells/uL, which is within the normal range (typically 4,000 to 11,000 cells/uL). Neutrophils are a type of white blood cell that plays a vital role in fighting infections. The percentage of neutrophils (N.seg) at 77.8% is slightly elevated, which could indicate a response to infection or inflammation. However, it’s not alarmingly high.

3. Lymphocytes: Your lymphocyte count is 17.6%, which is within the normal range (20-40% is typical). Lymphocytes are crucial for your immune response, and their levels can fluctuate based on various factors, including stress, infections, and chronic diseases.

Recommendations
- Monitoring: Given your current health status and the absence of significant abnormalities in your blood test results, it may not be necessary to repeat the tests immediately unless you experience new symptoms or your doctor advises otherwise. Regular check-ups, perhaps every 6 to 12 months, can help monitor any changes in your health.

- Medication: You mentioned taking "驱异乐" (likely an antihistamine or similar medication) for your urticaria (hives). If your symptoms have resolved, it’s advisable to consult your healthcare provider before discontinuing the medication. They can provide guidance on whether it’s safe to stop or if a gradual tapering off is recommended.

Conclusion
Your blood test results indicate that your kidney function appears stable, and your white blood cell counts are within normal limits, suggesting no acute infection. However, it’s essential to maintain regular follow-ups with your healthcare provider, especially considering your history of recurrent urticaria. They can guide you on the appropriate duration for medication and any further tests that may be necessary based on your symptoms and overall health.

In summary, understanding your blood test results can empower you to take charge of your health. Always feel free to ask your healthcare provider for clarification on any results or concerns you may have. They are there to help you navigate your health journey effectively.
