What does it mean if your BUN and creatinine are high?

Elevated creatinine level signifies impaired kidney function or kidney disease. As the kidneys become impaired for any reason, the creatinine level in the blood will rise due to poor clearance of creatinine by the kidneys. Abnormally high levels of creatinine thus warn of possible malfunction or failure of the kidneys.

What does elevated BUN and creatinine mean?

The blood urea nitrogen or BUN test is primarily used, along with the creatinine test, to evaluate kidney function in a wide range of circumstances, to help diagnose kidney disease, and to monitor people with acute or chronic kidney dysfunction or failure.

What is GFR in kidney function?
GFR - glomerular filtration rate is the best test to measure your level of kidney function and determine your stage of kidney disease. Your doctor can calculate it from the results of your blood creatinine test, your age, body size and gender.
What should a normal creatinine level be?
Results of the creatinine blood test are measured in milligrams per deciliter or micromoles per liter. The normal range for creatinine in the blood may be 0.84 to 1.21 milligrams per deciliter (74.3 to 107 micromoles per liter), although this can vary from lab to lab, between men and women, and by age.
What is the cause of kidney failure?
Insufficient blood flow to the kidneys can cause acute prerenal kidney failure. The kidneys can't filter toxins from the blood without enough blood flow. This type of kidney failure can usually be cured once you and your doctor determine the cause of the decreased blood flow.

What can you do for high bun?

If your kidneys are not able to remove urea from the blood normally, your BUN level rises. Heart failure, dehydration, or a diet high in protein can also make your BUN level higher. Liver disease or damage can lower your BUN level. A low BUN level can occur normally in the second or third trimester of pregnancy.

What is the reason for high bun?

A high BUN value can mean kidney injury or disease is present. Kidney damage can be caused by diabetes or high blood pressure that directly affects the kidneys. High BUN levels can also be caused by low blood flow to the kidneys caused by dehydration or heart failure. Many medicines may cause a high BUN.

What are bad numbers for kidneys?

If the upper number is over 140 and the lower number is above 90, your blood pressure is too high. Albumin to Creatinine Ratio - Estimates the amount of protein found in your urine in a day. Protein in the urine is one of the earliest signs of kidney disease. Less than 30 is normal, over 30, talk to your doctor.

What is the creatinine level for kidney failure?

Failure (F) - Increase in serum creatinine level X 3.0, decrease in GFR by 75%, or serum creatinine level ≥ 4 mg/dL with acute increase of >0.5 mg/dL; UO < 0.3 mL/kg/h for 24 hours, or anuria for 12 hours. Loss (L) - Persistent ARF, complete loss of kidney function >4 weeks.

What is the normal range for bun?

Results of the blood urea nitrogen test are measured in milligrams per deciliter (mg/dL) in the United States and in millimoles per liter (mmol/L) internationally. In general, around 7 to 20 mg/dL (2.5 to 7.1 mmol/L) is considered normal. But elevated blood urea nitrogen can also be due to: Urinary tract obstruction.

What is normal GFR for age?

Following the classical way, we can assert that normal GFR values are largely over 60 mL/min/1.73 m² in healthy subjects, at least before the age of 70 years. However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m² could be considered normal.

What does it mean to have a high EGFR?

A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.

What is the normal range for EGFR in blood tests?

According to the National Kidney Foundation, normal results range from 90 to 120 mL/min/1.73 m². Older people will have lower than normal GFR levels, because GFR decreases with age. Normal value ranges may vary slightly among different laboratories.

What are the main causes of kidney failure?

In the United States the two leading causes of kidney failure, also called end stage kidney disease or ESRD, are diabetes (also called Type 2, or adult onset diabetes) and high blood pressure. When these two diseases are controlled by treatment, the associated kidney disease can often be prevented or slowed down.

How do you test for kidney disease?

Your doctor can do very simple tests to check for kidney disease:

Measure the level of serum creatinine in your blood to estimate your glomerular filtration rate (GFR)
Measure the level of protein in your urine (increased levels of protein show your kidneys are not working right)
Check your blood pressure.

Why do doctors check creatinine levels?

A creatinine blood test measures the level of creatinine in the blood. Creatinine is a waste product that forms when creatine, which is found in your muscle, breaks down. Creatinine levels in the blood can provide your doctor with information about how well your kidneys are working.

What is a kidney function test?

Your kidney numbers include 2 tests: ACR (Albumin to Creatinine Ratio) and GFR (glomerular filtration rate). GFR is a measure of kidney function and is performed through a blood test. Too much albumin in your urine is an early sign of kidney damage. Urine Test called ACR.
