Creatinine Levels in Kidney Function
Checking creatinine levels is key to seeing how well your kidneys work and stay healthy. This part will look at what these levels mean, the creatinine test, and why some levels could mean kidney failure.
What Are Creatinine Levels?
Creatinine comes from your muscles and a bit from the meat you eat. Healthy kidneys filter it out and send it in your pee. The creatinine test checks how much creatinine is in your blood. It tells us about your kidney health.
Normal vs. Abnormal Creatinine Levels
Knowing what’s normal for creatinine levels is important. What’s normal changes based on your age, gender, and how much muscle you have.
| Group | Normal Range (mg/dL) | Potential Kidney Failure Indicator |
|---|---|---|
| Adult men | 0.6 to 1.2 | Greater than 1.2 |
| Adult women | 0.5 to 1.1 | Greater than 1.1 |
| Teenagers (13-18 years) | 0.5 to 1.0 | Greater than 1.0 |
Kidney Failure Labs – Key Tests Explained If your creatinine levels go up, it could mean your kidneys are not working right. This might be a sign of chronic kidney disease or kidney injury.
GFR Test: What You Need to Know
Kidney Failure Labs – Key Tests Explained The Glomerular Filtration Rate (GFR) test checks how well your kidneys filter blood. It’s key for checking kidney function and health.
Overview of the GFR Test
Kidney Failure Labs – Key Tests Explained The GFR test measures how fast your kidneys remove waste from blood. By looking at blood levels, doctors can figure out your estimated GFR. This shows how well your kidneys are working.
This test is important for finding early signs of kidney disease. It also helps track how kidney disease is getting worse.
How GFR Test Results Are Used
GFR test results help Diagnose and track chronic kidney disease stages. Doctors use these results to see how serious the disease is. It can range from mild to kidney failure.
Knowing the stage helps doctors make the right treatment plans. This is key for helping patients with kidney disease.
| Chronic Kidney Disease Stage | Estimated GFR (mL/min/1.73 m2) | Description |
|---|---|---|
| Stage 1 | > 90 | Normal or high |
| Stage 2 | 60-89 | Mild decrease |
| Stage 3a | 45-59 | Mild to moderate decrease |
| Stage 3b | 30-44 | Moderate to severe decrease |
| Stage 4 | 15-29 | Severe decrease |
| Stage 5 | Kidney failure |
Doctors use the estimated GFR to manage patient care. They can see the chronic kidney disease stages and adjust treatments. This helps patients get better care and keeps their kidneys healthier.
Blood Urea Nitrogen (BUN) Test
The Blood Urea Nitrogen (BUN) test checks how much urea nitrogen is in your blood. It’s a key test to see how well your kidneys are working. If BUN levels are high, it might mean your kidneys are not working right or there’s another health issue.
Understanding the BUN Test
This test looks at the nitrogen part of urea, a waste made in the liver from proteins. The kidneys then get rid of this urea through urine. By testing BUN, doctors can check if your kidneys are working as they should. Kidney Failure Labs – Key Tests Explained
Significance of BUN Levels
Checking BUN levels can show many health problems, like not having enough water or serious kidney disease. High BUN levels often mean kidney problems.
