The EGFR, or estimated glomerular filtration rate, is calculated the same for all adults and is not determined by the race of an individual. The EGFR is a test that measures the amount of serum creatinine found in the urine. A normal range for adults with normal kidney function is 0.8 to 1.3 milligrams per deciliter for males and 0.6 to 1.1 milligram per deciliter for females.Continue Reading
Several things may influence the EGFR level in adults. Young adults with large muscle mass may have a higher serum creatinine level than elderly adults, as creatinine production is based on total muscle mass. Certain medications also may increase the production of creatinine in the body.
An EGFR is used to detect chronic kidney disease and to track the progress of treatments used. A 24-hour creatinine-clearance test is another test used in the treatment of chronic kidney disease, but the EGFR test produces more reliable results.
Chronic kidney disease is common in individuals with hypertension, diabetes, systemic infections and autoimmune diseases. Individuals who have a family history of chronic kidney disease are also at risk for developing the disease, and regular testing of creatinine levels is essential in prevention and treatment. An EGFR is not a suitable test for women who are pregnant, people who have an acute illness or people who have other serious medical comorbidities, as the test may not be a reliable indicator of chronic kidney disease in these populations.Learn more about Molecular Biology & DNA
There is no way to improve the glomerular filtration rate, but paying attention to kidney health can keep the number from decreasing, according to the National Institute of Diabetes and Digestive and Kidney Diseases. A glomerular filtration rate below 60 may indicate kidney disease, and a rate under 15 may indicate kidney failure.Full Answer >
Stage four kidney failure is an advanced stage of kidney disease where a person has advanced kidney damage and a decreased glomerular filtration rate, states DaVita Kidney Care. A person at this stage of advanced kidney disease likely needs dialysis or a kidney transplant in the near future.Full Answer >
The eGFR test determines the glomerular filtration rate of the kidneys, which indicates how well the kidneys are functioning, states MedlinePlus. A blood sample is needed to determine eGFR, which is calculated using a formula that includes factors such as creatinine level, age, ethnicity, gender, height and weight.Full Answer >
DNA profiling works by mapping the section of an individual's genome that varies from that of other people in the population. Since most human DNA is identical, only a relatively small section of the total genome needs to be sequenced to achieve a positive identification for paternity, forensic or archaeological purposes.Full Answer >
