Urinalysis Results: What Your Doctor Didn't Explain - Internal Medicine

More Info

---

Based on the urinalysis results you've provided, let's break down the findings and address your concerns regarding the UACR (Urine Albumin-to-Creatinine Ratio) and its implications for your kidney health.

1. Understanding the Results:
- Albumin (尿蛋白尿): 10 mg/dl
- Creatinine (尿肌酸酐): 10 mg/dl
- Protein: Negative
- Glucose: Negative
- Specific Gravity: 1.007
- Occult Blood: Negative
- eGFR: 90
2. Calculating UACR:
The UACR is calculated by taking the urine albumin concentration and dividing it by the urine creatinine concentration. In your case:
- UACR = (Albumin in mg/dl) / (Creatinine in mg/dl) = 10 mg/dl / 10 mg/dl = 1.

3. Interpreting UACR:
- A UACR of less than 30 mg/g is considered normal, while a UACR of 30-299 mg/g indicates microalbuminuria, and a UACR of 300 mg/g or more indicates macroalbuminuria.
- With a UACR of 1 mg/g, your results indicate that you are well within the normal range, suggesting that there is no significant albuminuria, which is a positive sign for kidney health.

4. eGFR:
- An eGFR of 90 is also within the normal range, indicating that your kidneys are functioning well. The eGFR is a measure of how well your kidneys filter blood, and a value above 60 is generally considered acceptable.

5. Specific Gravity:
- Your specific gravity of 1.007 is on the lower end of the normal range. This could indicate that your urine is relatively dilute, which can occur with high fluid intake or certain medical conditions. However, it is not necessarily a cause for concern unless accompanied by other symptoms.

6. Conclusion:
- Overall, your urinalysis results appear to be normal, with no signs of significant kidney damage or dysfunction. The absence of protein in the urine and a normal UACR are reassuring indicators of kidney health.

7. Recommendations:
- Continue to monitor your kidney health through regular check-ups, especially if you have risk factors such as diabetes or hypertension.

- Maintain a healthy lifestyle, including a balanced diet, regular exercise, and adequate hydration, to support kidney function.

- If you have any symptoms or concerns in the future, do not hesitate to consult your healthcare provider for further evaluation.

In summary, your urinalysis results do not indicate any abnormalities, and your UACR is well within the normal range. It's always a good practice to stay informed about your health and to follow up with your doctor if you have any further questions or concerns.
