A serum creatinine level of 1.4 and a positive leukocyte test in urine may indicate potential kidney dysfunction and the presence of a urinary tract infection (UTI) or inflammation. The elevated creatinine suggests impaired kidney function, while the positive leukocytes in urine typically indicate an inflammatory response, often associated with infection. It is advisable to conduct further diagnostic evaluations to determine the underlying cause and appropriate

Hello Dr.
Yang: Recently, during a group health check, I saw two results in the report: creatinine level at 1.4 and the urine test showing leukocytes as +-(indicating the presence of both positive and negative results).
My height is 175 cm and weight is 68 kg, and everything else is normal.
What do these test results indicate? How can I improve this situation? Thank you.

Hello: In response to your question, the report mentions a mildly positive urine leukocyte count and a creatinine level of 1.4.
Given your height and weight, a creatinine level of 1.4 is slightly elevated compared to normal values.
The creatinine level is related to the amount of muscle tissue in the body, and it may be slightly higher in males than in females.
Therefore, you should visit a nephrology clinic for a repeat blood test to confirm whether it exceeds the standard value.
As for the mildly positive leukocyte count, it may indicate a slight urinary tract or prostate infection.
It is important to monitor your fluid intake and avoid holding in urine.
A repeat urine test should be conducted to check if it remains positive, after which a decision can be made regarding the need for treatment.

Elevated creatinine levels and the presence of leukocytes in urine tests can indicate underlying health issues that warrant further investigation. In your case, a creatinine level of 1.4 mg/dL is above the normal range, which typically falls between 0.6 to 1.2 mg/dL for most adults. Elevated creatinine levels may suggest impaired kidney function, as creatinine is a waste product produced by muscle metabolism and is normally filtered out by the kidneys.
The presence of leukocytes in urine, indicated by a positive result, often suggests an inflammatory response, which could be due to a urinary tract infection (UTI), kidney infection, or other inflammatory conditions affecting the urinary system. The fact that your urine test shows both positive and negative leukocyte results (indicated as + and -) may suggest that the presence of leukocytes is intermittent or that the test may have been borderline.

To interpret these results accurately, it is essential to consider other factors such as your medical history, any symptoms you may be experiencing (like pain during urination, frequent urination, or back pain), and any medications you are currently taking. It is also important to note that dehydration can lead to elevated creatinine levels, so ensuring adequate hydration is crucial.

Here are some steps you can take to address these findings:
1. Consult a Healthcare Provider: It is vital to discuss these results with your healthcare provider. They may recommend further testing, such as a repeat creatinine test, a urinalysis, or imaging studies like an ultrasound to assess kidney structure and function.

2. Hydration: Ensure you are drinking enough fluids, particularly water, to help your kidneys function optimally. Dehydration can lead to elevated creatinine levels.

3. Dietary Considerations: A diet low in protein may help reduce the workload on your kidneys. Foods high in potassium and phosphorus should also be moderated if kidney function is compromised. Consulting with a dietitian who specializes in renal health can provide personalized dietary recommendations.

4. Monitor Blood Pressure and Blood Sugar: High blood pressure and diabetes are significant risk factors for kidney disease. If you have a history of these conditions, managing them effectively is crucial.

5. Follow-Up Testing: Regular monitoring of kidney function through blood tests (like creatinine and blood urea nitrogen) and urine tests can help track any changes over time.

6. Lifestyle Modifications: Engaging in regular physical activity, maintaining a healthy weight, and avoiding smoking can contribute positively to overall kidney health.

In summary, elevated creatinine and the presence of leukocytes in urine tests can indicate potential kidney issues or urinary tract infections. It is essential to follow up with your healthcare provider for a comprehensive evaluation and tailored management plan. Early intervention can help prevent further complications and maintain kidney health.
