A major measure of kidney function is the glomerular filtration rate (GFR). The glomerular filtration rate is the flow rate of filtered fluid through the kidney. The creatinine clearance rate (C Cr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR.
The normal range of GFR, adjusted for body surface area, is 100–130 average 125 (mL/min)/(1.73 m 2) in men and 90–120 (mL/min)/(1.73 m 2) in women younger than the age of 40. In children, GFR measured by inulin clearance is 110 (mL/min)/(1.73 m 2) until 2 years of age in both sexes, and then it progressively decreases. After age 40, GFR ...
A glomerular filtration rate (GFR) ≥ 60 mL/min/1.73 m 2 is considered normal without chronic kidney disease if there is no kidney damage present. Kidney damage is defined signs of damage seen in blood, urine, or imaging studies which includes lab albumin/creatinine ratio (ACR) ≥ 30. [ 59 ]
The CMP I just got back makes a distinction between the value of my eGFR based on whether I'm African American or not. The article on eGFR states that is because "It is known that African Americans...have a higher amount of muscle mass than Caucasians; hence, African Americans will have a higher serum creatinine level at any level of creatinine clearance."
The 2010 U.S. Census further specifies the number of Americans who identified with each racial and ethnic group; in 2010, 38.9 million identified as African American, 14.6 million as Asian American, 2.9 million as American Indian or Alaskan Native and 50.4 million as Hispanic or Latino.
By 1490, more than 3,000 slaves a year were transported to Portugal and Spain from Africa [1] African Americans made up almost one-fifth of the United States population in 1790, but their percentage of the total U.S. population declined in almost every U.S. census until 1930. [5]
