Kidney Health

The eGFR value provides insight into kidney health:

• A value above 90 is considered normal.
• A value below 60 suggests potential kidney dysfunction.
• A value below 15 indicates severe kidney failure,
• requiring immediate medical attention.

Men typically have higher creatinine levels than women due to their greater muscle mass. A serum creatinine test, commonly part of a kidney function test, measures creatinine levels in the blood to assess kidney health. Normal creatinine levels are up to 1.2 mg/dL for women and 1.4 mg/dL for men. Elevated levels may indicate impaired kidney function, suggesting that blood purification is not occurring effectively.

Both high and low sodium levels can contribute to kidney issues and symptoms such as nausea, loss of appetite, and fatigue. Elevated sodium levels may also result from consuming foods rich in sodium. Monitoring sodium levels is crucial for maintaining kidney health and overall well-being.

Why It’s Done:
Your doctor may recommend a kidney blood test if you exhibit symptoms of a kidney problem, including:

• Blood in your urine
• Reduced urine output
• Swelling in the hands, feet, or abdomen
• High blood pressure
• Unexplained fatigue
• Persistent nausea or vomiting
• Chest pain

Purpose of the Test:
The results can help your doctor assess the severity of any kidney issues and decide if treatment is necessary. Additionally, the test may help rule out other potential causes of your symptoms.

How to Prepare:
Fasting: You may need to fast for 12 hours before the test—no eating or drinking during this time.
Medications: Inform your doctor about any medications or supplements you are taking, as some may interfere with test results. You might need to temporarily stop certain medications before the test.
Key Points:
A kidney blood test is a simple, quick procedure that provides essential insights into your kidney health. If you have any questions or concerns about the test, speak with your doctor for guidance.
