Kidney Functions Measurement In Children Been Improved

A study published on Wednesday 21st, in the Journal of the American Society of Nephrology revealed that a formula used to measure kidney functions in children have been improved. This study was led by George Schwartz, M.D.

To know the functional accuracy of the kidneys GFR is estimated. GFR, Glomerular Filtration Rate; the volume of water filtered out of blood through Glomerular capillary walls into Bowman’s capsules. From there the waste material is taken to the urine system. It is the most reliable assessment to check kidney functions.

It is difficult to undergo this assessment procedure each time as it is time consuming and costly. Therefore, different methods have been tested and tried in the study to replace GFR successfully. These methods include Schwartz formula and Scandinavian method.

To undergo the research, both the formulas were compared using a technique of disappearing of the X-ray dye Io from serum. GFR was over estimated in the Schwarz formula, as the Io method can be used once in two years in CKiD; Chronic kidney Disease in Children.Whereas, to evaluate kidney function accurate results can only be taken.

After further tests and trials, it was found that closest results like Iohexol can be derived from Schwartz formula to estimate GFR after slight modifications. It was modified by using serum creatinine, cystain C (a protein found in blood) blood urea nitrogen, gender and weight.

George Schwartz said, “The relationship between estimated GFR and the biochemical markers may be different in this population than in a population with more normal kidney function and without poor skeletal growth”.
