Iwhiwhu1, Adebowale Adebiyi1 1Department of Physiology, College of Medicine University of Tennessee Health Science Center Glomerular filtration rate (GFR) is the ideal marker for assessing kidney function. However, the standard measurement method using inulin injection with serial blood and urine analysis is impractical. This article delineates a practical method to measure GFR transdermally in piglets.
