Kidney Function Tests (KFT's) Explained| Serum Creatinine, Serum Albumin, BUN, eGFR, and Urinalysis

Summary

This video explains kidney function tests, crucial for evaluating kidney health and diagnosing renal disease. It covers various tests, including blood tests for blood urea nitrogen and serum creatinine, which assess waste levels filtered by the kidneys, and the estimated glomerular filtration rate (eGFR), indicating overall kidney function. Urinalysis is highlighted as a key test for detecting early signs of kidney damage, such as proteinuria. The video aims to educate viewers on the importance of these tests in monitoring kidney health and treatment responses, encouraging them to engage further by subscribing to the channel.

Takeaways

• 😀 Kidney function tests assess how well the kidneys are working and are crucial for identifying renal disease.
• 🩸 Blood tests measure substances filtered by the kidneys, including blood urea nitrogen (BUN) and serum creatinine.
• 🔍 A normal BUN level ranges from 7 to 20 mg/dL; high levels may indicate kidney dysfunction or other health issues.
• 💪 Serum creatinine levels typically range from 0.7 to 1.3 mg/dL for men and 0.6 to 1.1 mg/dL for women, with elevated levels suggesting impaired kidney function.
• 📉 Estimated glomerular filtration rate (eGFR) is a critical test that reflects kidney filtering efficiency, with a normal result usually being 90 mL/min or higher.
• 📊 Low eGFR levels may indicate chronic kidney disease (CKD) or other factors affecting kidney function.
• ⚖️ Serum albumin levels, ranging from 3.5 to 5 g/dL, help assess kidney and liver health; low levels can signal disease.
• 💧 Urinalysis checks for signs of kidney disease, including proteinuria, which indicates potential kidney damage.
• 📅 Regular kidney function tests are essential for monitoring treatment responses and disease progression.

Q & A

What are kidney function tests and why are they important?

Kidney function tests evaluate how well the kidneys are working. They are important for identifying renal disease, monitoring kidney treatment responses, and determining the progression of kidney disease.

What types of tests are included in kidney function tests?

Kidney function tests include blood tests, urine tests, imaging tests, and kidney biopsies.

What does the Blood Urea Nitrogen (BUN) test measure?

The BUN test measures the amount of urea nitrogen in the blood, which provides important information about kidney function.

What are the normal ranges for blood urea nitrogen levels?

The normal range for blood urea nitrogen levels is typically between 7 and 20 milligrams per deciliter (mg/dL) in adults.

What might elevated blood urea nitrogen levels indicate?

Elevated BUN levels may indicate improper kidney function, potentially caused by dehydration, heart failure, liver disease, or kidney disease.

What is the significance of the serum creatinine test?

The serum creatinine test measures the level of creatinine in the blood, indicating how well the kidneys filter waste.

What are the normal serum creatinine levels for men and women?

Normal serum creatinine levels generally range from 0.7 to 1.3 mg/dL for men and 0.6 to 1.1 mg/dL for women.

What does a low estimated glomerular filtration rate (eGFR) indicate?

A low eGFR indicates impaired kidney function and may signal chronic kidney disease (CKD) or other conditions affecting the kidneys.

How is urine analysis useful in assessing kidney health?

Urine analysis, or urinalysis, examines urine samples for signs of kidney disease, including the presence of protein, which can indicate kidney damage.

What is proteinuria, and why is it significant?

Proteinuria is the presence of protein in urine, which is one of the earliest signs of kidney disease and suggests potential kidney damage.
