Creatinine levels in the blood can vary depending on age and body size. A creatinine level of greater than 1. As kidney disease progresses, the level of creatinine in the blood rises.
This test is a measure of how well the kidneys are removing wastes and excess fluid from the blood. It is calculated from the serum creatinine level using age and gender.
Normal GFR can vary according to age as you get older it can decrease. The normal value for GFR is 90 or above. A GFR below 60 is a sign that the kidneys are not working properly. Once the GFR decreases below 15, one is at high risk for needing treatment for kidney failure, such as dialysis or a kidney transplant.
Urea nitrogen comes from the breakdown of protein in the foods you eat. A normal BUN level is between 7 and As kidney function decreases, the BUN level rises.

This increased risk is partly caused by factors common to both chronic kidney disease and cardiovascular disease, such as high blood pressure. However, researchers are discovering that chronic kidney disease is, in itself, an important risk factor for the development of cardiovascular disease, and a history of cardiovascular disease is a risk factor for the development of chronic kidney disease.
The kidneys regulate water and salts, remove certain wastes and make various hormones. Kidney disease increases the risk of cardiovascular disease in many ways, including:.

The best measure of kidney function is the glomerular filtration rate GFR , which can be estimated from a blood test that checks the blood for creatinine a waste product made by muscle tissue. A biopsy means that a small piece of tissue is taken for testing in a laboratory. Biopsies used in the investigation of kidney disease may include:.
