Calibrating kidney function for cancer patients

Cold Spring Harbor Laboratory (CSHL) scientists have developed a new model for assessing kidney function in cancer patients as part of an international collaboration that involved contributions from the United Kingdom and ...


How blood and wealth can predict future disability

Blood tests for 'biomarkers' such as cholesterol and inflammation could predict whether you will be disabled in five years—according to research from the University of East Anglia.

Renal function

Renal function, in nephrology, is an indication of the state of the kidney and its role in renal physiology. Glomerular filtration rate (GFR) describes the flow rate of filtered fluid through the kidney. Creatinine clearance rate (CCr) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR. Both GFR and CCr may be accurately calculated by comparative measurements of substances in the blood and urine, or estimated by formulas using just a blood test result (eGFR and eCCr).

The results of these tests are important in assessing the excretory function of the kidneys. For example, grading of chronic renal insufficiency and dosage of drugs that are primarily excreted via urine are based on GFR (or creatinine clearance).

It is commonly believed to be the amount of liquid filtered out of the blood that gets processed by the kidneys. Physiologically, these quantities (volumetric blood flow and mass removal) are only related loosely.
