Frequently Asked Questions on Kidney Functions Tests

Kidney function tests play a crucial role in assessing the health and functionality of the kidneys. These tests provide valuable information about the kidneys’ ability to filter waste products, maintain electrolyte balance, and produce hormones. In this article, we will delve into the details of kidney function tests, their meaning, normal range, parameters checked, ways to improve results, and the impact of abnormal values. We will also explore the best fruits and foods to support kidney health and maintain optimal kidney function.

Frequently Asked Questions on KFT

Q: What are the common types of kidney function tests?

A: The common types of kidney function tests include serum creatinine, blood urea nitrogen (BUN), glomerular filtration rate (GFR), and urine albumin tests.

Q: What is the purpose of kidney function tests?

A: Kidney function tests help evaluate the health and efficiency of the kidneys in filtering waste products, maintaining electrolyte balance, and producing hormones. They are used to diagnose and monitor kidney diseases and assess overall kidney function.

Q: What is the normal range for serum creatinine?

A: The normal range for serum creatinine is approximately 0.6 to 1.2 milligrams per deciliter (mg/dL) for adult males and 0.5 to 1.1 mg/dL for adult females. However, the range may vary slightly depending on the laboratory.

Q: What is the normal range for blood urea nitrogen (BUN)?

A: The normal range for BUN is typically between 7 to 20 mg/dL for adults. Again, the range may vary slightly depending on the laboratory.

Q: How is the glomerular filtration rate (GFR) measured?

A: GFR is typically estimated using equations that take into account factors such as serum creatinine levels, age, gender, and race. It provides an estimation of how well the kidneys are filtering waste from the blood.

Q: What is the urine albumin test used for?

A: The urine albumin test measures the amount of albumin, a protein, in the urine. It helps identify kidney damage or disease by detecting albuminuria, the presence of albumin in the urine.

Q: How can I improve my kidney function test results?

A: To improve kidney function test results, it is important to adopt a healthy lifestyle.
Stay hydrated, follow a balanced diet low in sodium and saturated fats, control blood pressure and diabetes if applicable, and avoid excessive protein intake. Consult with a healthcare professional for personalized recommendations.

Q: What are some fruits and foods that support kidney health?

A: Fruits and foods that support kidney health include berries, leafy greens, citrus fruits, garlic, onion, whole grains, and fatty fish high in omega-3 fatty acids. These foods provide essential nutrients, antioxidants, and hydration that can contribute to healthy kidneys.

Q: What are the consequences of abnormal kidney function test values?

A: Abnormal kidney function test values can indicate kidney dysfunction or disease.
Elevated levels of serum creatinine, BUN, or urine albumin may suggest impaired kidney function.
Low glomerular filtration rate (GFR) values may indicate decreased kidney function. These abnormalities may be associated with conditions such as kidney disease, urinary tract infections, or other kidney-related disorders.

Q: Is it necessary to fast before kidney function tests?

A: Fasting is typically not required for kidney function tests. However, it is always best to follow the specific instructions provided by your healthcare provider or the laboratory performing the tests.
