Q:

What is EGFR for a non-African American?

A:

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.

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.

    What is an eGFR test?

    A:

    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.

    What is non-Mendelian genetics?

    A:

    Non-Mendelian genetics describes any pattern of inheritance that does not follow the basic gene segregation seen in Mendelian genetics. Non-Mendelian laws of inheritance describe traits that are only linked to one gene on chromosomes. Conversely, Mendelian genetics refer to traits in which two parents both contribute an allele.

    What is non-Mendelian inheritance?

    A:

    Non-Mendelian inheritance refers to any pattern of genetic inheritance that does not pass traits on according to Mendel's laws. There are several patterns of non-Mendelian inheritance in which genes have incomplete dominance, co-dominance or multiple alleles.
