Three high issues (referring to high blood pressure, high


Hello Doctor: I recently had a basic blood test, and here are the results: eGFR: 80 (Is this low?), ALT: 12 (Does this indicate that my liver is healthy?), Uric Acid: 5.1 (Is this high?), TG (Triglycerides): 63 (I previously had high levels; is this number okay now?), Total Cholesterol: 194, LDL (Low-Density Lipoprotein): 122, HDL (High-Density Lipoprotein): 64, Glucose AC (Fasting Blood Sugar): 84, HbA1c: 6.
I read online that an HbA1c over 5.6 is considered prediabetes, while my fasting blood sugar seems normal.
What do these two values mean together? Does it look like I am in the prediabetes range? I am very concerned because my mother has diabetes.
I kindly ask for your explanation and advice.
Thank you very much.

A hemoglobin A1c level of 6 indicates prediabetes, and regular monitoring is necessary.
Currently, dietary control is recommended.
Thank you for your inquiry.

Based on your recent blood test results, let's break down the key components and assess your risk for diabetes.
1. eGFR (Estimated Glomerular Filtration Rate): Your eGFR of 80 mL/min is generally considered to be within the normal range for adults, although it is on the lower end of normal. An eGFR below 60 may indicate some level of kidney dysfunction, but at 80, your kidneys appear to be functioning adequately. It's always good to monitor this, especially if you have risk factors for kidney disease.

2. ALT (Alanine Aminotransferase): An ALT level of 12 U/L is considered low and typically indicates that there is no liver damage or disease. Normal ALT levels vary by laboratory but are generally considered to be between 7 and 56 U/L. Therefore, your result suggests that your liver is functioning well.

3. Uric Acid: A uric acid level of 5.1 mg/dL is within the normal range for most laboratories (typically 3.5 to 7.2 mg/dL for men and 2.6 to 6.0 mg/dL for women). This means you are not at risk for gout or other conditions related to high uric acid levels.

4. Triglycerides (TG): Your triglyceride level of 63 mg/dL is excellent. Normal levels are considered to be below 150 mg/dL, so this indicates that your lipid profile is healthy.

5. Total Cholesterol: A total cholesterol level of 194 mg/dL is borderline high, but it is not alarming. The ideal total cholesterol level is below 200 mg/dL.

6. Low-Density Lipoprotein (LDL): Your LDL level of 122 mg/dL is also borderline high. Ideally, LDL should be less than 100 mg/dL for optimal heart health, especially if you have a family history of diabetes or cardiovascular disease.

7. High-Density Lipoprotein (HDL): Your HDL level of 64 mg/dL is good. Higher levels of HDL are protective against heart disease.

8. Glucose (Fasting Blood Sugar): A fasting blood sugar level of 84 mg/dL is considered normal. Normal fasting glucose levels are typically between 70 and 100 mg/dL.

9. Glycated Hemoglobin (HbA1c): Your HbA1c level of 6% is at the upper limit of normal. According to the American Diabetes Association, an HbA1c of 5.7% to 6.4% indicates prediabetes, while 6.5% or higher indicates diabetes. Therefore, your result is concerning as it is close to the threshold for prediabetes, especially considering your family history.


Conclusion and Recommendations:
Based on your results, you are not currently classified as having diabetes, but your HbA1c is close to the prediabetes range, and you should be vigilant. Here are some recommendations:
- Lifestyle Modifications: Focus on maintaining a balanced diet rich in whole grains, fruits, vegetables, and lean proteins while limiting processed foods and sugars. Regular physical activity is crucial; aim for at least 150 minutes of moderate exercise each week.

- Regular Monitoring: Given your family history of diabetes, it would be wise to monitor your blood glucose levels and HbA1c regularly. Consider retesting your HbA1c in 3-6 months to see if there are any changes.

- Consult Your Healthcare Provider: Discuss your results with your healthcare provider, especially considering your family history. They may recommend further testing or lifestyle interventions tailored to your specific needs.

- Stay Informed: Educate yourself about the signs and symptoms of diabetes, such as increased thirst, frequent urination, fatigue, and blurred vision. If you notice any of these symptoms, seek medical advice promptly.

In summary, while you are not currently diagnosed with diabetes, your HbA1c level suggests that you should take proactive steps to reduce your risk. Regular check-ups and a healthy lifestyle can significantly impact your long-term health.
