Assume in graphing these data that the independent variable is shown on the horizontal axis and the dependent variable on the vertical axis. 123.Refer to the above data sets. The variables are directly related in:
Share. Albumin is a protein present in the blood. Proteins are normally absent in urine because the kidney cells generally prevent large molecules including proteins, from being excreted. Some proteins may appear in the urine in normal individuals also if blood levels are very high.
ACR. Albuminuria. Albuminuria is increased excretion of urinary albumin and a marker of kidney damage. Normal individuals excrete very small amounts of protein in the urine. Albumin is the most common type of protein in the urine. All patients with CKD should be screened for albuminuria. Persistent increased protein in the urine (two positive tests over 3 or more months) is the principal marker of kidney damage, acting as an early and sensitive marker in many types of kidney disease.
