Pah clearance
WebIn HA rats, urea clearance was lower by 73%, inulin clearance by 61%, and PAH clearance by 56%, compared with C rats. The clearance values of these substances returned to the control values in DA rats. The data suggest that the low clearance values reflect both reduced renal blood flow and possible changes in the capacity of the glomeruli for ... WebGeorge Haycock, in Pediatric Urology, 2010. Renal Blood Flow and Filtration Fraction. RBF and renal plasma flow (RPF) are impossible to measure directly in healthy human infants. The renal clearances of para-amino hippurate (PAH) and the radiocontrast material diodrast have been widely used as an estimate of RPF, based on the assumption that these …

WebThe clearance of PAH is constant and high at low plasma [PAH], below the T m PAH. Under these circumstances the blood that perfuses the secreting portions of the nephron is nearly completely cleared of PAH. Under these conditions, the clearance of PAH approximates the effective renal plasma flow, ERPF.

WebAug 1, 1999 · The disparity between PAH clearance and true renal plasma flow was used to compute a value for the E PAH in those subjects studied by both clearance and MRI techniques. The E PAH for the allograft control group (n = 13) averaged 87 ± 10%. As shown in Fig. 2, the true renal plasma flow exceeded the PAH clearance in all but one of the 16

Para-aminohippurate (PAH) clearance is a method used in renal physiology to measure renal plasma flow, which is a measure of renal function. PAH is completely removed from blood that passes through the kidneys (PAH undergoes both glomerular filtration and tubular secretion), and therefore the rate … See more The renal extraction ratio of PAH in a normal individual is approximately 0.92, and thus not exactly 1.0.
